When thinking of the S30 chassis Nissan Fairlady Z & Datsun 240Z “sportier” model versions, most will probably point to the Japanese domestic Market PS30 (Z432) and PS30-SB (Z432-R). Some might also think about the Japan-only 240ZG (HS30-H) homologation special with the longer “G-Nose” front. While they are fine and sought-after collectors cars these days and indeed impressive performance cars for their time, there is one model often overlooked: The European “Final Spec” Datsun 240Z. In this story, I like to shed some light on the Euro-Spec cars, which are also known by the designation codes H(L)S30Q. How they came to life, who was responsible, the development process, the specifications,…

Today we’re going to have another deep-dive into a nerdy tech Topic: The original Nissan electric fuel pump on the S30 chassis 240Z and fairlady Z cars. DisclaimerAs with all my knowledge articles, i tried my best to get all information from trustworthy and official sources. However, i cannot guarantee that all information is 100% correct.

Many 240Z which are from USA come with an air conditioning system installed. After reading a few times in the local Z-chats that imported cars from USA came equipped with “factory air conditioning”, i thought it’s about time to share some deeper insights on this topic, and get some things straight. Disclaimer As with all my knowledge articles, i tried my best to get all information from trustworthy and official sources. However, i cannot guarantee that all information is 100% correct. If you have any correction, input or additional information, i appreciate if you let me know. I’ll update this post whenever i find something to add or change. I…

Recently a friend asked me if this suspension which he found for sale in Japan could be the real deal? But let’s start at the beginning.  Those who know my Suspension knowledge post (i have a bigger update on that planned soon), might know that Nissan / Datsun sold a set of adjustable “Competition” / “racing” / “Sports option” suspension kit: I don’t think they ever sold many of those and so they are extremely rare to see these days. so when the set from the first picture showed up, we had to investigate. The sales ad says it’s for the S30Z but the seller is not even sure. He…

Some of you more geeky readers might know that Nissan used to experiment with some electric fuel injection system in some of their works rallye cars. I’m no expert by any means, but i recently stumbled on this article of some guy who found an original set, and thought it might be interesting for some of the readers. Click to enlarge the pictures for full size view Here’s a photo from the very control box in the Datsun 240Z at the 1973 monte carlo rallye with the Drivers Tony Fall and Paul ester (Picture Jos van der Aart). Note the tape on the knobs to protect the drivers from changing…

Time for another geeky deep-dive into a not-so-common Datsun 240Z / Nissan Fairlady Z (S30) technical topic: The original steering system. Disclaimer: As usual with my knowledge posts, i put this together over the course of years, spent countless hours on this, bought rare factory documents and literature for reference and tried my very best to get all information from trustworthy and official sources. But still i cannot guarantee that all information is 100% correct. Sometimes not even the official factory documentation is really clear. Let me know if you found a fault. Also please ask before you use any of this! As with all my knowledge posts, i update…
