situatation

can't find much about the turbo and orginally assumed that it creates 320 rwhp @15psi was it limits, Thats about all i could find about it, so the rtek 1.7 should handle 5-8 psi ...one of my freinds was looking through some old sport compact car magazine and came across a artical of a guy dynoing 380 rwhp @15 psi with my same modifications just a pfc controled it. so now i need to get more fuel to the engine so it doesn't blow agian(just blew last week end) I don't want a engine to blow for somthing stupid like running lean, I really like the 1.7 but i'm gonna need the 2.0, or somthing more capable.

I went to rx7.com and used a fuel calculator
550X720 @75% will only support 274 flywheel hp
720x720 @75% will only support 311 flywheel hp

I do have a aic available with 2 injector support.

I understand that you can dial in bigger injectors but how big? Need some information one how i can do basically 400rwhp

Its getting late so i might have missed something..If you need more information about my car or what I'm trying to do ask me

i would upgrade to the 2.0 (or wait a few weeks for the 2.1), timing control can make a big difference in detonation prevention

As for injector sizing, im running 750&1000cc injectors with no problems. I think you may be able to go with 1600cc secondaries with the 2.1 (37% fuel correction)

you also have to remember when sizing injectors is that most manufactures rate them at 45 psi fuel pressure. a stock FC runs at 38psi, so they will not flow as much as you would think when you are still using the stock FPR
