stock injectors?

[jesse0880]

how much power to the wheels can i expect using the stock fuel system at about 14 psi? I'm trying to talk myself out of dumping more money into my car, but i want supra 550's

What gen and model do you have? . I'm guessing 2nd gen since you're talkin' Supra 550's. Just adding the injectors and uping the boost will only make you run pig rich without any gains. The stock turbo will never out run the stock fuel system. Even @16psi.
Alot depends on the condition of your engine. if you up the boost to 15psi and your engine is in good condition-maybe 200rwhp. and thats only a guess..
But if you do up the boost, you will feel the difference!

If you get 550s, you'll need a way to tune them. It costs a fair amount of money to get 550s running properly.

The stock 440s are good for up to about 250-275rwhp.
