It depends on how much power you are making. It has nothing to do with injectors.

ok i wasnt sure about that.. but it will probably be around 400 to the wheels.. LE2 h/c forged bottom end...

if you tune the car and the tune is compesating for some pressure lose a new pump will change the tune

Just pick up a racetronix kit. They are cheap and seem to work well.

maybe not needed.....but i'd change the pump for peace of mind. why risk leaning out your motor over a $150 pump. then you know you're good to go and won't chance being held up later on.

there is a shop by my house called Engineered Victorys Inc(EVI) that does dyno tunning so i think i might take it to them.. i hear they do good work.

stan seems pretty good. I would take the car there then put the injectors in.

they are gonna dump WAY to much fuel. and will wash the rings on a new engine. the pcm won't compensate during warm up or WOT and even then its really only about 2% that it can anyway

so tow it over there or could i get away with the ones that are in it just to get it there?

the stock ones would work. but I don't recommend starting it with bigger injectors. I gave my pcm to the tuner and he set the injector scale so I could start the car and do break-in before the real tune

ask brian about using bigger injectors untuned.


I just don't want anyone to hurt an engine becuase if bigger injectors.
