ok im building up my 12a turbo project right now and im trying to order all the parts i need so i can put everything togerther at once, my question is pretty obvious from the title,

goals,
250-350 hp,

mods, im building up the motor right now with a high pressure ropr, polished e-shaft, mild street port (very mild, basically smoothening the ports and taking of sharp edges) megasquirt and 2x50mm throttle body setup,(i can iether do 2 or for injectors)

im breaking in w/o turbo installed for obvious reasons.

plans for turbo, -aftermarket 2nd gen ballbearing turbo nothing huge, pretty big for 12a though, and custom turbo maningold

so should i get stock turbo2 injectors, or some aftermarket 1600cc ones, or what,

thanks
paul

 

I'd stage the injectors because at idle, you'll have a hard time tuning the pulsewidths. (The pulse to open the injector may have to be VERY short for a huge injector as any longer would dump too much fuel... There is such a thing as too short of a pulse though.)

Use something like TurboII injectors primary and GSL-SE injectors secondary.

 

i agree with the staging. run 550's primary and atleast 1000cc in secondaries. because if you are thinking about over 300rwhp you will need the fuel. and hell, 1600cc injectors are so cheap now you might as well step it up to that for the secondaries. that way you have room to go farther when you see fit. and that wont take long
