Injector Swap! 89 300zx.

[Daboss]

Hey forum what's up? If I didn't say it before Happy New Year to all! Now down to business, I need to know if the injectors out of an 89 300zx will swap directly into an rb25det. Someone wants to sell me a set but, I am not sure if they will drop right in. I am thinking no but, I just need confirmation as I am unsure. Thanks for your help in advance.

Im pretty sure its only the later 300zx that has the same injectors as rb25... 95-96 from memory

Ok thanks mate. Wow that was a super fast reply too. Great stuff.

89 was the first year Z32's came out so it's still possible that they are out of a Z32.. VG30DETT engine.. there may be some overlap though and they may be out of an 89 Z31 with the VG30ET engine.

Yep, the S3 Z32 sidefeed injectors should fit fine in a R33 RB25. They are 370CC stock for the TT ones. A lot of aftermarket injectors for the Z are the later model ones though, so if you are looking at a set of 740CC Nismo's then they should fit in fine.

Z31 are top feed.
