John: The stock STS kit comes with a 60-1, which makes almost 500HP on their dyno. I would really like a T-66 as I am using a T-64 now. The T-64 pulls strong to about 5000rpm, but it runs out of breath much above 5000 rpm.
Turbo is still available
The A/R for the second housing is = 0.68, which should make this turbo spool at 3000rpm (maybe a little more or less). This would be a killer street/strip setup! What to go racing with high boost and rpm? Then just swap exhaust housing for maximum performance. Thanks.
This is still available, and I also have an extra turbine housing. The extra housing is a 4 bolt with provisions for a Delta Gate. Revised price is $850 shipped for the turbo with both turbine housings. Thanks.
