Hey Im wondering what size of injectors I can get away with with my new setup, I have an s4 tII in the corolla, with a hybrid s5 turbo t04b cold side, free flowing exhaust, FMIC, and running microtech.

If I run around 12-14psi of boost can I get a way with 750cc secondarys? something bigger? whats too big?

Im clueless.

 

Might as well go with 1000cc

 

I'm running a to4b and I've got 680 pri and 1000 sec with a RTEK 2.1. It's probably a little overkill, but it leaves some headroom for upgrading and at 12-13psi seeing duty cycles around 60-70%.

yea I seemed to think 1000cc would be the general consensus, I guess ill keep my eyes out for a pair

 

^^^^I have a new pair of rc 1000s. Never been used I don't think.

What compressor wheel is going to be in it? V-trim? H-trim? 60-1? It'll make a big difference.

 

is it a bnr stage 2
