I've searched and only found partial answers. Im looking to get a set of ITR pistons for my b18c1, and I also have a set of ITB's off of a GSXR 750 that im gonna have installed, basicly what im trying to find out is, given those two mods alone, would I need or benifit by getting larger injectors? I do understand that I will need tuning, I do have a vafcII but I also understand that it isn't gonna do. In which case what would you recomend I use to properly tune it with... chipped ecu? hondata? ...and what not... And what kind of gains (roughtly) should I expect?


Thanks...

 

yes you will want larger injectors. i would say 310cc should be suffice for that setup. i would highly recommend looking into some more aggressive cams as well to help the motor work better with the ITBs

 

bump

 

so putting itr pistons in a gsr block u need bigger injectors??

 

pistons alone, no. I am pretty sure itr and gsr injectors are the same. But with itb's i would say yes.

 

have personally done something like that gsr block with ls crank and jdm itr pistions... it sucked waste of time and money. just my .02

 

well considering that it would bump ur compression like around 11.4 or something .. would make some power if u really want to get some raw power u could add a set of nice cams

Might help answer some injector questions.
