Need help with rx7 injectors in r33

[danieltangtc]

Hi guys

Is it possible to fit top feed high impedence 550cc rx7 injectors to the r33 gtst?

I was thinking of putting an r32 fuel rail in my r33 and fitting rx7 injectors to it.

Will the r32 fuel rails fit my r33?

Also, what do r33 boys usually do to fit rx7 injectors?

Dont know? But I heard somewhere that SR20 injectors are high impedence and will fit in the r33 injector rail. Dont quote me on this though it may be wrong.

Problem with the SR injectors is they are the same size, unless you manage to pick up a set of s15 injectors.

As for rx7 injectors, the rb20 rail doesn't fit. You would need a custom rail. Other than that no real issue with using them.

I was in the same position a few months ago when doing and rb20-25 swap. It was easier for me to sell the 550 top feeds that were fitted to the rb20 and get a set of 550 side feeds.

Ok so do the s15 injectors flow much more I guess they would be hard to find too.

Series 6 rx7 or 20B cosmo injectors are 550cc side feed and high impedence. These can be made to fit in the R33 rail with very little effort.
