I have a Precision turbo 74 aka SP74 .81 AR
It's a 74mm compressor.
Larger than the known 67mm greddy t-78
Larger than the known 71mm greddy t-88d. However the t-88d has a much larger exhaust housing. Both make around the same HP. But the sp74's have better spoolup characteristics for the dinky 3.0 liter.
Since your in the market I can give you a spin in it this weekend if ya wanna feel it. Most likely I'll be dumpin some rice fuel in it too.
There is going to be a black supra there that has the same turbo & transmission as mine. I guess he put down 900rwhp through the auto unlocked. But he's using nitrous also.
