HS30-H first, thanks for all knowledge which You shared with us. Now only way to describe what I'm trying to achieve now, is an attempt to get whole picture of this car. U see, 240Z is my dream car and I have to confess that it is extremely rare in Poland - so I can not just buy it. And U know, we have here some possibilities to buy, but some wrecks, or parts mostly. It's okay for me, I like the idea of saving one of these beautiful machines from certain death. Because I was able to put aside some money, I'm starting to consider an acquisition now. And I have ability to buy some dying 280, but first I would like to determine what will be the best choice. I started from gearboxes because this 280 has automatic, and this will need to change. I'd like to race later, so Im trying to follow the FIA approval too. Therefore I will have to buying parts around the world, that's why I want to be able to choose and describe them precisely. And I have to be very precise because my budget does not overthrow. (conversion rate is usually very negative for me) In other words Im trying to gather knowledge, that for example, will allow me to determine if there is any possibility co convert simplest S30 in to Z432, etc, etc. I wonder if anyone here tried collect all variants/pages of this 3023 homologation in to one complete document ? Im trying to search entire forum but it will take time. And now John, could U please share this automatic variant ?
