Well, personally I would go with the PT6766CEA's, however those would not be my first choice. Both are very close in power capabilities, but the Turbonetics unit just doesn't suit my fancy with the 68mm Turbine, I realize the Precision units is small but the fact that the 78mm Compressor has to be driven by a 68mm Turbine, its just not fun.

PT7675CEA would be too big IMHO for a street car.

And that is perfectly fine. I just think that 76's are too big for a street car. Also, why mention the AC? lol

a good tuner should be able to tell you how high the RPMs is gonna be and tell you why. The tuning is very important so make sure you get a good one
