ATENZA / FRIENDS: Emblems / Stickers / Wheel parts delivery

I always thought the Japanese “Atenza” name is way cooler than the european “Mazda 6”design_2nd-row_img3.ts.1503040225174530 - Kopie

So when making the big datsun order in Japan a few weeks ago i decided to throw in the JDM badge as well 🙂
P1170741 - Kopie

And since i plan to update the car with some simple mazdaspeed parts whenever funds allow me i decided to throw in a bunch of mazdaspeed stickers as well, since they are not available here: P1170739 - Kopie

and then i helped a buddy of mine who bought a set of RAYS wheels from japan for his project (more on that soon i guess) with some brand new Volk racing parts to refurbish his old wheels. From left to right: European air valves, Center caps, Wheel refurbishing stickers and some duraluminum Lug nuts at the bottom. Nice stuff and i’m sure the wheels will look awesome and like-new when done.  P1170750 - Kopie

240Z: Books, Diff adapters, Seat rails, wheel parts delivery

So before i went to vacation i ordered a lot of stuff from japan and elsewere and when i returned two days ago i had a load of boxes and envelopes waiting for me. that’s how returning from vacation makes fun 😀 So what was inside these boxes and envelopes?
A lot of reading material:

1) Brian Long’s Fairlady Roadster to 280ZX book. Probably the most complete Z-book i’ve come along so far.P1170728 - Kopie

2) Original JDM HS30 sports option parts catalogueP1170729 - Kopie

3) Original JDM sports option parts catalogue 1979P1170730 - Kopie

4) Japanese S30 Fairlady Z Complete book, by “Nostalgic  hero” Magazine.  Basically a small Mook that includes scans of all original japanese catalogues and so on. can be quite handy sometimes.P1170732 - Kopie

5) Original JDM Fairlady Z Sales brochureP1170734 - Kopie

cool thing is if you unfold it completely and turn it around it’s a Poster of a Fairlady Z 🙂P1170735 - Kopie

6) JDM Service manual for HS30, PS30, and S30P1170736 - Kopie

7) Only Z Book (Japanese). Probably similar to 1) but in Japanese, tons of informations about Z’s with many spec-tables and so on!P1170737 - Kopie

8) then got the JDM Parts list for the S30 on a CD. already have an other one as PDF file but this one is searchable so probably more handy…
P1170744 - Kopie

9) Now to the non-readable parts 😀 Since i decided to go the Subaru-R180 route differential was wondering what adapters i should use. Wolf creek, Beta motorsports or some others. until i figured out that Kameari makes them for the same price with import and the somehow look a bit more appealing and more OEM to me with the darker material used and so on. and then it’s Japanese too which i always prefer for personal reasons 🙂P1170742 - Kopie

10) and since i have a passenger seat now for the Z i also neaded a seatrail, and here it is 🙂  P1170751 - Kopie

Got more parts in the same deliveries for my other projects and friends. will probably post about it tomorrow 🙂

OTHER: The Cars of Sweden & My first Mantorp Park experience

Since i have a lot of family, friends and relatives in sweden it’s kind of a tradition for me to go there at least every second year to visit all of them. It’s also tradition to go there by car. While it’s not the most confortable way it’s definetely the most fun way to get there. On the way to my final destination around Västerås in Västmanland, i like to stop once or twice at a camping place (usually at a place i haven’t been before) to explore new places. Well and since we made 4500km’s in two weeks i thought the mazda would be the best choice of car and it defintely was. what a great, comfortable, smooth and spacey car!
P1170695 - Kopie

Since my girl isn’t too much into cars i thought i don’t want to plan the whole vacation around car events. We had planned the date of vacation early due to our work schedules and when i asked around if there are any cool events going on i only got one answer. The power big meet (see later). However nothing JDM related. I figured out i was twoo weeks to early for the annual Gatebil event at Mantorp park and nothing else to see, so i thought i just skip everything car related and if it fits into our tight schedule of visiting relatives and enjoying ourselves we might have a short sneak in at the power big meet. Well…
And then we followed my mazda’s navigation to my parent’s new place in sweden which led me a bit of a strange (but probably the fastest) route to that area, and suddenly i saw a sign at the road: Mantorp. Our brave mazda led us there, hehe 🙂DSC_0392 - Kopie

I have never been there before because i usually go to different areas in sweden but since the gate in the back was open i just HAD to have a look. It was already late in the evening and just a regular saturday or so, so there was no action going on but at least on the parking area a few guys were packing up their race cars:
P1170294 - Kopie

You might know that scandinavians have incredible backyard-engineering skills and build world-class racecars on a budget…P1170295 - Kopie

We sneaked around a bit but decided proceed to our destination.P1170296 - Kopie P1170297 - Kopie P1170298 - Kopie P1170301 - Kopie

At my parents place i checked the mantorp website to figure out that every first monday of the month there is a public trackday. I din’t have any helmet or fire-proof suit with me so i wouldn’t be allowed to race but i thought yeah – maybe more to see then, right? As it was only a 1hour detour to our next destination i thought why not drive by on monday and have a look? that’s what we did:P1170302 - Kopie

unfortunately again there was not too much going on. a small group of porsche and corvette owners were racing around on the track.P1170411 - KopieP1170400 - Kopie

P1170402 - Kopie

and then there was this little guy too 🙂
P1170409 - Kopie

after a few minutes of wandering around we decided to have a look at the paddock area:
P1170410 - Kopie

it was less spectacular than expected. but hence beeing a monday morning i guess most of the cool cars would probably come in the afternoon…anyhow. after a while we saw these guys unloading a pretty serious time attack corvette:P1170407 - Kopie

P1170398 - KopieP1170399 - Kopie

It was surprisingly quiet on the track but seriously fast 🙂P1170401 - Kopie

these  guys also had this cool motor-powered mini-car to drive around the paddock 🙂P1170408 - Kopie

otherwise there wasn’t too much to see. at least one fairlady in the paddocks    P1170412 - Kopie

and later on the track.P1170422 - Kopie

accompanied by this Scirrocco R:
P1170417 - Kopie

After a while we decided to move on with our roud trip and on our way out of the area i pointed my camera into the two workshops which had open garage doors in the pit-area. one seemed to be a serious race-shop.P1170423 - Kopie

The other one was a radical dealer and Formula car trackday rental / racing school shop:P1170424 - Kopie

on our way out i couldn’t refuse to force my girl to make a picture of myself driving out the driveway (it’s not the track unfortunately) of Mantorp park. I swear next time i’m in sweden i will try my best to get to the gatebil at Mantorp!P1170427 - Kopie

However in västeras there is this thing called “Power big meet”. It’s worlds biggest US-car / Rockabilly Meeting. Seriously it is! people come there from all over the world and sweden has a crazy amount of american sleds and muscles. So during the two weeks in sweden we saw at least 30 (really!) or so american classics on the road every day. some of them seemed to follow us the entire two weeks 🙂P1170513 - Kopie


I thought it wouldn’t be too interressting to me, but as closer as the event came (and we even passed the city of Västeras one of these days) i regretted to not have planned to go there as there were so many cool people and cars driving around on the street and i would have loved just to have a look at a different car culture for fun. Well that was it. on our way back we saw a bunch of mazda MX-5 roadsters in The city of Roskilde, some of them seemed to be quite a bit modified 🙂P1170726 - Kopie

Well. that was it. next time i definitly will organise my things around some car events 🙂

OTHER: Honda S600 “Barn Find”

A While ago my Buddy Stefan, Manuel and I and went to a special place with a lot of cars and carparts. Unfortunately they didn’t have any Z-Parts so i left a bit earlier since i had the longest drive back home. A few weeks later Stefan calls me and tells me the owner of this place told him about a Honda S600 or S800 which is somewhere in the huge area.

In total one complete car and two in parts. Since one of my friend is one of europe’s biggest Classic Honda S-Chassis specialist and another one is currently restoring two of them i thought this might be interresting. I asked Stefan to send me some pictures when he goes there next time and that’s what he did – Thanks a lot 🙂

After all it looks like only one Car, and with the ornamet in the hood, i guess it’s an S600 car and not an S800. Also i talked to the guys mentionend above and it seems like there are quite some Stocks with parts so it seems like the interrest in this parts was not as big as i thought.

Nevermind. If somebody is interrested, get in contact with me, i may be able to arrange something. But note that it’s not my car, i live two hours from tha place and cannot just drive by and pick something up and also i’m pretty sure the owner knows the value of these parts. so don’t expect lowballer prices but also the prices are not horrendous or something.

Available parts are (See pictures):
-1 chassis
-2 hoods
-2 Trunks
– 1 Windscreen
– 1 Folding roof
– 1 Front End metal piece
– 4 Wheels
– 2 Seats
– Lots of small bits and pieces (See pictures) and probably a lot more

It looks like some rats lived in the chassis for some time, but overall i guess most of the parts are still useable and restoreable.image10

And, the rest of the pictures. thanks for your support Stefan.image12 image13 image14 image21 image22 image23 image24 image25

ATENZA: OEM Accessory Tray

I know it’s nothing big (Some small bits from Japan are on the way and some bigger plans for the future are there), but since we’re making a big roadtrip in our trusty and spacey Mazda 6 soon, i thought i’d upgrade my Mazda a little bit with an accessory Tray, which is a Mazda dealer accessory:

240Z: JDM L6 Aftermarket Intake Manifolds & Turbo Surge tanks

Ok, i started this post about intake Manifolds a while ago when i was looking for one. Meanwhile i got a nice, oldschool FET intake sitting in my shelve and waiting to be refurbished and installed. Well however since then i found more and more other options and thought i make Post about all classic and Modern Intake manifold Options from the Land of the rising sun. Im a JDMjunky after all 🙂 I know there are plenty of other (mainly US) options but this is about the japanese only.

Sanyo Kiki / SK / S-
Japanese brand which still exists, but has been splitted into different groups and doesn’t produce intakes under that brand name anymore (See below). I so far found three different designs:
The Very first one was marked with “S-三” only:
s-l16005 - Kopie

The second version is marked with “SK” and “SANYO”, while the overall functional design seems to remain the same.
SK old - Kopie

SK Sports kit
Was a complete Kit sold with a later Sanyo Kiki intake cast-design but also came with the carbs and everything. Quite a popular choice and i like it:
SK sport - Kopie

OER Corporation
In 1983 Sanyo-Kiki was splitted into different branches and their Carb-business got renamed to OER Corporation. Since then the old SK-kits have ben redesigned and sold under their new brandname either as Intake only or complete OER Sports injection kit (Still available new through OER Japan):


Tomei powered
Was available new until around late 2014, not anymore sadly. If you compare the pictures it seems like this is an almost 1:1 copy of the datsun Competition Intake (See below)tomeimkl - Kopie

Datsun Competition
Datsun USA / Nissan Japan sold this intake Manifold as an optional “sports” Intake for the Mikuni / Solex PHH44 Intakes (Picture from the 1978 Competition catalogue): 1978 datsun comp - Kopie

FET / Far east trading / Kyoku-To
Here we have an early Kyoku-To Design Intake manifold (Kyoku-To = Far east)FET old - Kopie

Later versions came branded as F.E.T. and had the additional Balancer tube on top. This is what i got for my car. I heard the balancer tube makes idling adjustment a bit tricky but i got it mainly because of the finned design will fit my Kakimoto valve cover excellently.
Compared to some other brands this one has very short funnels which is great if you don’t have much space.
P1150443 - Kopie P1150449 - Kopie

EXCEL / Solexcel
A reader of the European DPAN Facebook group emailed me a picture of his “Excel” Intake manifold kit:
13516264_298911203775351_5811818961973100799_n - Kopie

I first wasn’t sure if it was a japanese brand at all, but a bit of googling and i found some adverts and pictures of similar Kits for the A14 Engine (Pictures courtesy of Unfortunately wasn’t able to find more Information or Pictures from an L-series Setup or Kit.Excel - Power kit - JDM - Kopie

It seems like they were among the first companies to use dyno’s to tune their stuff. Their kits are sometimes also dubbed “Solexcel” Kit which is a complete kit with Solex Carbs and Excel manifolds, etc…Excel Power Kit 2- JDM - Kopie

Mikuni is mainly known for their Famous Carbs (actually they built Solex carbs in licence) But they also had their own intake manifolds for the L6 Engines (picture shows a repainted one)
Mikuni - Kopie

Like most others Mikuni sold a complete Kit Including carbs and all the bits for the  L6 Motor:
Mikuni 2 - Kopie

Harada Shokai
Looks pretty similar to many other designs but is still available and probably the technically most advanced, modern and best engineered design. aside from all the annodize bits i think it looks very oldschool 😉Harada_M1002 - Kopie

Kameari Racing
Intake Manifolds are still availabe new from kameari Japan for various carb sizes and applications. UPDATE: I got noticed that Kameari just re-sells Harada Shokai intakes. and comparing the pictures this might be very true. Unfortunately i cannot understand the japanese text in the kameari catalogue to confirm this. but most probably this is true as the Pictures, partnumbers and kits look very similar and still both are available 😉 Unfortunately often referred to as “Kameari Intake” which is wrong since it’s a Harada 😉
Kameari Manifolds - Kopie

Here’s a closer look at one of them:Kameari 44mm Intake manifold - Kopie

Hayashi racing
So far only got this single picture showing a Hayshi racing L28 Intake manifold and i’m not sure if it will fit the other L6 heads but it looks beautiful:Hayashi L28 - Kopie

UPDATE: Found another picture on ebay:
Hayashi 5

HKS Surge Tank version 1
Now to the Turbo side of Things. The rare (and sold expensively nowadays) HKS Surge tank Version 1 was an early design. Not sure what L6 Engine (L20, L24, L26, etc) it was built for. most probably the L24. I first thought it was just some kind of an airbox to put on the carbs and then add a Turbo on the front. But my buddy Krisztian explained that these have a pretty smart design so that the venturi principle also works under turbo-pressure and it has an almost perfect airflow to the carbs. pretty crazy for that age. These kind of setups are also known as “Blow-through-Turbo-Setup”:

HKS Surge Tank version two
Used a more modern Cast design and was made for the L28 Engine according to the Catalogue picture below.Unbenannt - KopieUnbenannt2 - Kopie

SANY1288 - Kopie

HKS Twin Turbo Setup
If you compare the pictures above and below, the little “Add-on” part on the surge tank looks different. but the one in the catalogue below is stated as a Twin Turbo kit in an official HKS Ad, and i guess it was used mainly for the popular drag-racing back in the days then 🙂

Ad in old Carboy Magazine, Provided by Jeremy Wilbur – Thanks a lot!13179415_1080843995306602_764442320290251650_n - Kopie

HKS St. Turbo Kit
Aside from the mainly Z-based kits shown above and below, HKS Also offered a Turbo “Upgrade” kit for the C210 Skyline “Japan” which already came with a low-pressure L20ET turbo-Engine from the  Factory. This Upgrade kit with a bigger turbo and the Piping would improve power. I guess this one will also fit other L-series engines but not sure about that (and probably needs extra parts from a factory-turbo L-series to fit the non-turbo engines)

Tomita Auto “Hayate” Turbo Kit:
A Company called Tomita Auto (By Race Driver Yoshikazu Tomita, later part of famous Tommy Kaira) made a very similar Turbo Kit for the Fuel Injected L-Series Motors called the “Hayate” (Storm / Gale) Turbo Kit (See also here)

Here is an old ad for the kit:
bdcf036680 - Kopie

SK Compo Turbo Kit:
Since Big power-figures was all the rage back then, not only HKS came up with a turbo / Twinturbo kit but also Sanyo Kiki. There was the SK Compo Turbo Kit which was more or less an Blowthrough-Airbox for their SK Sports kit mentioned at the beginning of this post, similar to the HKS System.
Unbenannt3 - KopieUnbenannt4 - Kopie

The picture below shows a similar SK Compo kit used with the SK Sports kit for a twin-turbo setup (See turbo manifold at the bottom), but i’m not sure if Sanyo-Kiki ever officially sold this kit or if it was just custom-made out of the normal Compo Turbo Kit:blogger-image-1509684505

Here’s an ad showing what i guess is the full kit including the piping to the left and on the right side the “Standard” SK sports kit with Solex carbs and SK Filters 😉

Well there are/were other Japanese Manufacturers like Ohtsuka and so on but sadly wasn’t able to find any pictures of these. if you have some Pictures, Data or Ads, i would be very interrested!! Get in contact if you have some pics or information or know anything about another Japanese manufacturer i missed here. i’m pretty sure there are more out there 🙂

I’m sorry to say that some of These Pictures are not mine. I Collected them over many years from the Internet and unfortunately i was often not able to track down the the original source anymore.
The sources i know are
– Kameari engineworks Catalogue
– Harada Shokai Website
– Various Ebay sales
– Datsun Competition Website lots of old SK ads!

If any of These Pictures are yours i will happily add your credits or remove them upon request. I tought it’s ok to post it here since it’s about General interrest to every Z-owner to get some knowledge and history and sadly too much of this Information already disappeared in some bookshelves or the depths of the Internet.

240Z: Factory Transmissions knowledge, overview, Options and Specs

Ok guys, now it may get a bit techy in this post 🙂 I collected A LOT of information about transmissions over the past months and i’d like to put them all together into one single post. A lot of information is floating around the internet but it’s tricky to puzzle it all together, keep the overview and sort out the wrong information.
This post is focusing on the 1970-1974 240Z and will not include a lot of information about later transmissions nor any Information about the Transmissions in the L20 / S20 equipped JDM only models (thus JDM L24 model is included).
Trust me, it’s complicated enough.
And just sayin – some Data may be incorrect but i tried my best to get it right 🙂
P1160981 - Kopie

1. Transmission type code key / identification
Before we start, first a Key to understand the transmission type code.
I already listed this in the past, but decided to make a better graphic for easy overview.
Note that this chart is only about Manual transmissions:
240Z factory transmission code key

2. Factory transmissions:
2.1. Overview:

Depending on the country and year, there were different Factory Transmission options. But there are two main groups used in the 240Z:

Early “A-type”  (1970 to late 1971, varying a bit depending on country and Type)
Later “B-Type” (1972 to 1974, Also used in later Generation Z’s and other cars)

The “Type-Letter” is refering to the last Letter in the transmission model code.
Early type for example is FS5C71A, later type FS5C71B, and so on, see code chart below.

Within each of these two main Groups, there are similar three subgroups:
Nissan 4-Speed Manual, Nissan 5-speed Manual and JATCO 3-speed Auto. 

I made an overview Including the Type-code for easier understanding (click for full size):
Factory transmission overview
2.2. Transmissions according to Markets:
Which transmission was available in your cars market? Well – you can find this information in your FSM (Service Manual) but here’s an overview:

USA & Canada (LHD): 4-speed Manual and 3-speed Auto*
Europe (LHD): 5-Speed Manual
UK (Europe RHD): 5-Speed Manual
Australia (RHD): 5-Speed Manual, 3-speed Auto
Japan (RHD): 5-Speed Manual, 3-speed Auto
*Optional and competition transmissions are not included in this chart

Here is an Example of the 1972-1974 Service manual listing all B-type transmissions according to the dedicated market-model (first row).
For earlier model years, just replace all “B” with “A” in the transmission type code 🙂
B-type transmissions

3. Optional transmissions and Gearing
In Europe and Japan there were optional competition and racing Gearsets and complete gearboxes available for the Z’s. Here for E.g. JDM “Nissan Sports options”:

In USA however it was a bit different since they never got the 5-speed Manual Box:
– They offered Retrofit-Kits to install the Roadster 2000 (SR311) FS5C71A Transmission to the 240Z
– From 1977-1983 the 280Z FS5C71B Gearbox got available with optional competition Gearsets (and probably as a complete gearbox) which was also used as competition or racing part in the 240Z’s (with optional shifter-kit if used in an 1970-1971 car!)
– Anyhow a few sources mention that at least at some point the Euro / JDM A- and B-Box was also sold officially as an optional part.
Here’s a Pic of the 1978 USA Datsun 240Z Sports Option catalogue for example:
option tranny parts usa
See complete list of Factory and optional transmissions / gearsets below.

4. Differences between A-, A- and B-type(s)
First a bit of history. The early 5-Speed “A-Type” Transmission was not developed for the 240Z, but carried over from the Datsun roadster 2000 (SLR311) and probably also used in other older Datsun models.
To fit the L-series motor and the 240Z Specs, the 240Z-Transmission was fitted with a different clutch bell housing, longer mainshaft, tail Extension casing and one of the shift rods is different too.
That’s why the Roadster Gearbox is often refered to as “short tail” and the Z-Gearbox as “Long tail” Fs5C71A Transmission.
The US market got 4-speed non-overdrive gearing, but im not sure if there was an A-type 4-speed maybe used previously in other datsun’s as well..
Here’s a picture of a FS5C71A “short tail” from a Datsun Roadster (From the Roadster FSM)
FS5C71A (roadster2000)

While here is a view of the FS5C71A “Long tail” from the Datsun 240Z (Picture from the Nissan Motorsports schematic Catalogue). Also see the first Pic at the top of this post, which is the FS5C71A Factory European Spec 5-speed that came with my two early 1972 240Z’s.


Then there is the B-Type from the 1972+ 240Z which is a complete redesign of the “A-type” transmissions.
– The biggest difference is the two-piece Bellhousing of the A, while later B-type has a single piece bellhousing.
– Another visual difference are the Cast-fins on the outside of the housings as seen in the pictures above and here:
FS5C71B transmission

Here is a comparison between the A- and B-type from the S30 from the japanese G-works Fairlady Z S30 Magazine vol. 2:

– The A-type got the infamous so-called “Monkey Motion” rubber mounted shifter-stick while the B-type shifters have a solid cross pin. Later Model C-types are retained in a top cover plate by a circlip (Called “Top Loader” in american trannies):
– The gear ratios were different on both A- and B-types (both in 4- and 5-speeds)
– Due to the redesign the Shifter stick position is moved stlightly to the front in the “B-type” (See below).
– There were also other changes so be careful when swapping transmissions!
– Note that the B-type Transmission was used over a Long time and in several cars after the 240Z, so it got various design-changes in later models which will or will not fit the 240Z 1:1.

Here’s a Comparison between the 240Z transmissions, Left to right:
FS5C71A “Long tail” 5speed from the 1970-1971 240Z (non-US)
FS5C71B 5speed from the 1972+ 240Z (non-US)
FS5W71C from Later Datsun / Nissan model cars
3N71B Spline Type 3-speed Automatic (1972+ non-Euro 240Z)

4.1. Transmission interchangeability
4.1.1 Datsun Roadster 2000 FS5C71A into 240Z:
In America People used to install the Roadster 2000 FS5C71A transmission to get a 5-speed into their Z. This Retrofit was officially sold by Nissan / NISMO USA.
I was able to find a receipt of someone who bought this swap at a nissan dealer including all the part numbers needed:
FS5C71A Conversion kit reciet1

4.4.2 A-type with A-type
Swapping an Manual A-type 4-speed to a 5-speed should be a simple thing without any modifications needed since both have similar length and shifter positions.
A 4 vs 4 speed

4.4.3 A-type to B-type
Here you can see a A-type US-spec 4-speed Transmission (front) and a B-type US-spec 4- or 5-speed in the rear. According to the source, both transmissions are within a small fraction of an Inch of each other in total length. The 510 Transmission identification Manual (See Documents below), Says that all 4- and 5-speed both A- and B-types of the 240Z have a total length of 31.5In / 775mm, so this might just be within the tolerances.
Trans Change Shifter dif Type A Type BTrany 001

You can see the Centerline of the “A”-Shifter in the foreground (line #3) sits about 2.25 inchehs behind the Center line of the B-type Transmission (rear, line #1).
Line #2 is the rear end of both transmissions.
Trans Change Shifter dif 001
To install a Later B-type five Speed, which was sold as Competition Part in US at one Point in a car that was initially equipped with an A-type (four Speed) Transmission, Nissan sold the “Shifter Kit” (Part number 99996-E3030) as seen on the B-type Transmission in the back. It’s basically a bent stick where the original one is straight. The Shifter kit is not available anymore (Courtesy Nissan Information to my request in 2016) but i guess you can just bend the original stick. Also a different propeller shaft is needed.

The shifter sticks are not interchangeable between A and B-type and 4- and 5-speeds. Center Consoles A- and B-Type?
There are two different types of Center consoles. One with the Ashtray in front of the stick (1970-1971) and one behind (1972 and later). Some sources say that’s because of the difference in shifter stick Position in A- and B-transmissions (See above).  I Made a picture for comparison:
Consoles comparison

I cannot confirm above information, since both of my cars came with the Early A-type 5-speed and the later Center console with the ashtray behind the stick (See picture below). This would be a wrong combination according to the sources but i’m pretty sure this was the factory equipment in both of my cars:P1170175

4.4.4 Later Datsun / Nissan transmission swaps:
There are possibilities to swap to a huge array of different Datsun / Nissan Transmissions, but to not make it more complicated for the Moment, i will make a separate post about this Topic later.

5. Transmission / gearing overview:
I made an overview based on existing overviews and doublechecked everything with FSM’s, schematics, competition catalogues, E-Fast database, Original Micro-fiches and so on for hours. however sometimes some data was not 100% clear. anyhow i think this is the most complete overview about 240z Transmissions and (later) Options.
Note that this list is not 100% complete since there were also optional single gears to choose and 4-speed optional gears which i didn’t include in the list.
Also note that the part number for the same part may be different in different markets or may have changed over the time.

If text is coloured in a certain colour this means the “source” with the same text-colour mentioned this data, while all the other sources mentioned the black text. Sometimes it’s obviously a typographic Error but in some cases im not sure.

Also note that there are several other Datsun / Nissan 71A/B Transmissions and Gear kits wich will fit the original transmission and / or L-Series motor but not listed above since they were used in different cars. The list above only contains transmissinos wich were used by factory or sold as option through nissan for the 240Z / Fairlady S30 in different markets.

6. Brass “Warner” vs Servo “Porsche” style steel Synchros.
There are both Porsche style steel servo synchros and Warner style Brass synchros. What’s the difference? I  have no own experiences but i found following information online:
– The porsche type reacts slower than the warner type
– Porsche type shifts smoother than Warner type
– Porsche type snycros dislike being “speed shifted” (probably due to lower reaction times)
– Warner type is great for drag racing (Fast shifting possible due to fast reaction times)
Since all “competition” transmissions came with porsche synchros despite having slower reaction times, i guess they can handle slightly more power and / or last longer under heavy usage compared to brass synchros. Otherwise it would not make a lot of sense to have these in “competition” (or non-US standard) gearboxes.

7. Spareparts
Spareparts – especially for the early manual 5-speed are hard to find these dase, but below you find some adresses that still sell some parts:…

240Z: Transmission disassembly part 1

I’m working on a huge post about Z Factory transmissions and options but i decided myself i’d rather get some physical work done on my transmission while the weather is nice. The goal is to check the state of my original FS5C71A factory five-speed (non-US-spec) and then decide if i’ll stick with the stock transmission or switch to the FS5W71C transmission from the S14 which i bought a while ago.
So this is how i started on saturday:
P1170164 - Kopie

Decided to give the transmission a little cleanup with some engine cleaner before i get my hands on it:P1170165 - Kopie

Then drain the transmission oil before proceeding to avoid a huge mess in front of my garage:
P1170168 - Kopie

The magnetic Oil drain plug has surely collected a bit of metal debris showing some wear to the transmission. Doesn’t look too dramatic to mee but i’ll have to ask the pro’s 😉
P1170169 - Kopie

Then the infamous “monkey motion” sthifter stick pin had to be removed from the gear-selector rod. This pin-assembly usually tend’s to wear out and feel loose but i have to say it felt pretty solid and direct in my car. so probably doesn’t need too much rework in t his area.P1170167 - Kopie

Next was to get the flange-connector off the output shaft. Was quite tricky without air-tools / rattle gun but a trusty hammer, a big ratchet and some elbow-grease later i was able to remove it without any damage to anything or anyone 🙂P1170170 - Kopie

Next i removed all the bolts on the rear extension cover. Note the smaller bolts on top and bottom and the larger ones on each side.P1170171 - Kopie

Before proceeding further i thought it might be a smart idea to remove the reverse switch as well:P1170172 - Kopie

Then i carefully hammered the rear extension housing off using a wood piece to prevent damage to the housing:P1170173 - Kopie

So far it looks promising. wasn’t able to find any damage on the gears but as soon as i have the clutch bell housing and the front cover removed and all gears are visible i will have a collegue of mine check through all the gearing, synchro rings and so on. Will get the covers repainted and all the seals replaced. You can clearly see the Porsche type Steel servo synchros in this picture. Kind of weird how they sold this as a “Competition” option in USA while it was factory equipment in the rest of the world 🙂 Part two coming soon…P1170174 - Kopie

RACE: GP Diessenhofen 2016

The title says “race” but honestly i didn’t really get what the event was about yet. The homepage lacks a lot of information and there were some showlaps in the morning and some “race” laps in the afternoon but i have no clue if it really was a race or more timed showlaps. Nevertheless we had a few fun hours at the GP Diessenhofen today.

I heard the first time about the event last year and since it’s only 40minutes drive from my place we decided to have a look. It’s a very small track through the historic city Center of Diessenhofen directly at the river Rhein and then surrounding the city bit.

At the show laps in the morning you had possibilities to get taxi-rides in the cars for 20 bucks only so this sounded like fun. We ended up checking out the exotic machinery before the showlaps, then looking at the showlaps and then heading home during lunch-time before the rain came in. The cars were divded in four groups, the first one beeing supercars of modern and older generations:

Between all the barking and noisy ferrarris and their owners who liked to rev the engines it was kind of fun to see this BMW i8 silently passing by with nothing but a “swissssh” 🙂

This AC Cobra definitly had the nicest sound of all the supercars:





Then there were the Open wheelers and formula race cars which i personally liked most:

Particulary liked this one with the “John player Special” Livery 🙂





Then there were several racecars based on street-cars of all kinds and colours:


Some of them beeing very exotic and expensive i guess 🙂

While some were from the cheaper end of the scale but none less interresting. Not sure if i’ve ever seen an Autobianchi A112 Abarth before 🙂

Classic race mini allways makes me smile. P1170199


And then there was an array of cars which reminded me very much about the hillclim cars i see every year. Allthough i have to say i wasn’t really sure where the cars were usually used because some of them i was very unfamiliar with. Which didn’t mean they were less spectacular 🙂P1170224


The last group was about british Sportscars with some more or less exotic brands Like TVR:


Or the AC 3000ME With Ford Engine:


Classic Lotus Elan  P1170195

Or how about a Marcos? 🙂P1170196

All kind of cars were on stage 🙂P1170226

In between the local cart-racing club put some showlaps in their racekarts. Must be fun to drive on public streets in these things 🙂      P1170222

After all it was a fun few hours to spend a sunday morning. Still i’m not really sure what the event was about but it was interresting to see some exotic and rare cars and there really was a cool mix of cars and brands 🙂        P1170192
