what are they can anyone tell me what the size for the 90 turbo ones are and the 87 or 88 gxl?? i was told that u can run more fuel with the 88 gxl ones. anyone know

 

N/a injectors are 460cc and TII injectors are 550cc injectors. Your sources are WRONG.

 

wow that was fast...thats what i thought, thank you...would you happen to know, see i'm tryin to do a rebuilt with a street port and i wanna get about 400 out of it but i know i need to change the ecu and the injectors, what kind should i go with ?

 

Injector sizes for all RX-7s are in the FAQ.

If you're wanting to make 400HP, you will certainly need larger injectors and a standalone. 720 primary, 1600 secondary (lots of breathing room). Turbo upgrade, intercooler upgrade, fuel pump, basically everything.

 

For an engine computer you want something like Haltech, Microtech, or Wolf.

For injectors you probably want some 720 primaries and some 1600 secondaries along with a good fuel regulator and a serious fuel pump.

Good luck with it!

Dang Aaron you beat me
