Need some help
I'm looking for a turbo that will fit my power goals. I have a t3 manifold and were prefer to run a external waste gate. I'm looking to make 350-400 at the wheels. I called top speed and they recommended a Garrett gt3076r with a .63 A/R. Then I called jay racing and he recommended a precision 5857 with a .63 A/R. Then I called precision and the tech there said to go with a 5558 with a .82 A/R. So now I'm all kinds of lost. Anyone have any input at all.
