gIt is a great turbo for a street car because it spools up quick and provides adequate power. It also didn't seem overly touchy to throttle input nor run out of steam too badly, but i only have experience with a wrx to compare to ... which by the way is a super small turbo that gets the **** spun out of it and runs out of power so much that there is no point in even going up to redline.

Thanks. Excellent input.
I am working with Mazda Motorsport to develop a Spec Miata Turbo racing series package. So far Greddy has pushed their product, and now Rotrex, through Oscar Jackson is pushing their SC unit.
I am now going to be dealing with Garrett, so just doing some research.
Here is a dyno pull with the Greddy.
Remember this is going to be a spec series, with several endurance races, so we are limiting HP, but want maximum early torque to "get out of the corners".
Fuel system will be limited to stock Pump, FPR and injectors, 1.6 motor only.

I have a 2554 that was sopposedly rebuilt with a T28 wheel. I have my doubts though considering the person I bought it from. Either way Im running it at 13 psi and Im bored.

I want a 2560.
