OK Guys after looking through everyones sites and asking the same question I have come to the conclusion. Nobody knows anything about intake castings! So with that said I would like everyone to go out and look at your car(s) and respond back with year(ZorZX), Trans type(auto or stick), regular or 2+2, block casting, head casting, and intake casting. Where do I find the Intake casting number You may ask? It is about 3 inches back from the TB on top of the Intake. It will be a letter and two numbers ie(N47). My hopes are to find all of the differn't casting numbers and link them with years and models. If your engine is not original i will definatly need Block and head casting numbers. This only applys to 75-83 280Z and ZX fuel injected cars. Thank you for your support, lets make this happen so we can all learn from it.Thanks Josh
