OTHER: I’ve got world’s first turbo Kit (HKS C100 Skyline L20 Street Turbo)

If you’re familiar with japanese cars and Turbocharging, HKS is THE brand to know. What many people don’t know ist that Mr. Hasegawa (The “H” in HKS) was the very first one in the world to develop and sell an Aftermarket Turbo kit in July 1974 for the JDM-market Single-careburated C100 “Kenmeri” Skyline. And this is what i just got in my mail today 🙂

Appereantly it’s the second version with the HKS brand, since the first version came non-branded as seen in the picture from the HKS website history part below. You can clearly see the later design of the better known L20 Surge-tank kit in the lower left pecture and the very first version with only “turbo” on the top.

A bit of Japanese googling revealed some more pictures of the very first HKS demo car 🙂

Unfortunately a request at HKS revealed that all of the old drawings, partlists and marketing information has been scrapped and they were not able to provide useful information. However i will try again. This is how the kit looks from the Top, saying “Street, HKS and Turbo”. The housing is Cast aluminum and surprisingly light for that age:

The black Can on the back is an overpressure-valve and the white thing on the left most probably a pressure-sensor (You can see the tip of it in the center-hole).

I guess the lower hole was connected to the turbo, while the hole on the side was connected to a Turbo manifold:

It once was clearly painted in black wrinkle-paint whilte it appears the letters have been unpainted. It seems obvious that this is the original paint. at least what is leftover from it.

This is how it looks disassembled:

Here’s some information roughly translated from this japanese website: http://yamada25tm.exblog.jp/5910080/

There was a Kenmeri turbo that FET and HKS jointly developed and produced. This is an introduction of the actual test article!:
This Kenmeri Turbo is based on the Regular Gas Model of the JDM 2000 GT (Single Carb, L20 engine), the compression ratio has been changed to a low pressure of 8.0:1 by the original gasket.

Power specifications are 160PS / 6000rpm, 23kgm / 4500rpm! . Performance is 0 – 400 m at 16.9 seconds and the maximum speed is recorded at 180.90 km / h … (both measured values). This spec value lightly surpasses the Japan turbo appearing 6 years later, and it exceeds the Kenmeri 2000 GT – R equipped with S20 unit.

First of all I’m asking anybody who has more information on this to contact me. I’m interrested in anything from Pictures to ads to more information on this. This is the only i’ve ever seen.
Depending on what information i find i will have it professionally rebuilt and try to source or recreate the other parts, Or i will just paint it back to original glory and use it as a decorative wall art and piece of automotive and JDM history goodness.
Of course im also willing to sell if the price is right and i know it will end up in good hands…
