Need new injectors with my SBRt67... HELP!!!

[quik4g63]

Currently, i have 650 cc injectors and I am running 90% duty cycle under 20 PSI boost to maintain an 11:1 a/f ratio with no knock on my g4cs 2.4L.

I am not certain how much further I am going to be able to push this turbo on Sunoil 94 octane fuel and still have no knock.. My question to you is which injectors should i buy that i won't have to worry about upgrading again on 94street fuel? i know i could just buy the biggest injectors available but if its not necessary... i dont see the point of spending the extra money. Once i've achieved the highest boost i can on 94, i will then consider meth injection, but never race fuel...

Engine is a 2.4L g4cs, wiseco pistons Manley rods, T67SBR, 650FIC, Tial 44mm external, 3" turbo back gutted cat, dsmlink 2.5, 43.5 base fuel pressure, wally 255, GM 3" MAF with translator, ACT2900 6puck sprung. broken trans.

PLEASE HELP this money is burning a hole in my pocket

well, to be honest just think about it if all you are worring about is lowering injector duty cycle, then you dont have to move up much from where you are, so i would assume that 850 cc injectors would bring the duty cycle down

It all depends on what your using for a computer. You can get big 1000cc FIC's and just adjust the duty cycle wit your computer. Just as long as you tune it when u put in the bigger injectors.

950 Blue max, Should do the trick.
