GT60 and GT67 STS turbos I was wondering what were the a/r on these two turbos (normal 60-1 / GT67 ) and how much hp each can produce. (Turbo Spec HP)
I am not 100 percent that is the turbo for the regular STS setup.
For example I know the t-70 supports 700 hp but that is what I read about...but I am still looking

Here is a link to a car we did a 383 stroker on, the sts kit had the 67mm variant. Spool is great with the converter. At 7psi this car is a rocket, i have not felt 13.5psi which is 708 on our mustang dyno. The midrange torque compared to a procharger is amazing on this setup. A 72mm or a 76mm turbo would make for great top end power on this combo.

I started with the 60-1 and It spooled real quick but seemed not to take the car to redline. And it sounded like a small turbo real high pitched wine. I changed out to the T-70 and it takes a little longer to boost, even with the same size A/R. But man it pulls so hard. It also sounds like a damn jet engine
The base 60-1 taps out around 475 rwhp, that was at 8 psi, with a .81 a/r. I skipped straight to the T76, so I don't know the answer to the question on the 67. My 76 is a .96 a/r, and it has hit 10 psi by around 3500 rpm.
