I have a PT74. It has a .96 or .98 A/R....funny that when I was building it people were commenting about having a turbo that is too small....The boost could be a little more responsive if I tweaked on the boost controller....I will say that the power comes on really smooth and as a result I don't have any traction problems. Even when I turn the boost up to 15 psi I stay hooked up in 2nd gear....Oh about how I picked the turbo. I didn't. I bought everything (engine, ECU,clutch,ignition, turbo,exhaust..etc.) as a package from a guy that had been collecting the parts to build his car. It was a deal I couldn't pass up and I ended up with what he picked out. I've been pretty happy with it to be honest...not sure I would do too much different. Thanks for the comments.
