I discovered that one of the blades on my turbo is chipped, and now its making a whining sound like its scraping the housing when its spinning, so my car has been sitting for a couple of days now.

I don't have the cash for a new turbo right away but i do have my old header/intake. Is it possible to have the car tuned on my current 750cc injectors without a turbo? or would it be too much? (yes noob question.)

info:
B16A motor
750cc fuel injectors
garrett t3/t4 turbo
running stock bottom end
GSR cams and titanium retainers in the head

 

Just buy some stock 240 injectors and call it a day. Run a p72 gsr map, what tuning software are you running>?

 

But you have money for a tune? I ask because if you could do it yourself you would have.

 

Wait, its already tuned to use 750cc injectors boosted, so unless your tuner was a total dip, the vacuum map would have also been tuned accordingly. They should still be ok even without boost, or am I wrong?

 

I don't think you are. With no turbo, it'll never go into boost. That's all. Unhook the charge piping to make sure.

 

Sorry for the late reply things been busy exams and all.

Well it costs around $200 to tune the NA engine and around $700 for a decent turbo with shipping international it gets expensive and its a daily driver so i need it as fast as possible. (still a student I don't make that much money).

And yes I completely missed that its already using the big injectors without boost (its not building boost).

One last question, would I be able to run stock injectors on the current tune for 750 injectors?(just to get to the tuner) or would this damage the motor?

 

Just leave it the way it is. Don't make it complicated. No boost. No harm. No foul.
