How many pounds of boost can the F2T engine support. What is the most recomendable. Thanks a lot for your help.

About 12-14 without a fuel system upgrade.

And with a fuel system upgraded, How many pounds of boost can the engine support?

I've heard that the max is 17psi on stock internals. I've been running 15psi for over 30K miles, and I have 171K on the car now with an upgraded turbo. I had it at 17psi, but without race gas there is too much detonation and the knock senser retards the timing and it only boosts 15psi anyway.

I see that you have throttle body in your signature. What kind?
