OK, i have been doing some research, and I am ready for an injector controller. I am wondering what yall reccomend. I have a 1991 n/a and I am running the stock injectors, and fuel system. The reason I need a fuel controller is because I will be running n20 in the very near future. Apex, Greddy, HKS, what? Thanks guys!!

 

Apexi super AFC

 

That's what I thought. Thanks!!

 

Yep- get 550cc secondaries and an S-AFC.

I may be corrected here, but I beleive that NOS on an already modded rx7 would definately need 550cc secondaries...
Don't want to lock the 460's.

 

I see. I was under the impression the stock fuel system and a S-AFC would handle a 50-70 shot just fine. Any other ideas?

 

^^^^^^

 

with a wet NOS system you don't add more fuel. it does it itself.
