Cliff,
Sounds like a good combo, I have a customer we built almost identical, cept for the rear suspension being all Wolfe racecraft parts. I used the GT42, non BB, he's been a best of 9.10@148 on 26lbs of boost. He's also been a best of 1.28 60ft. and weighs in around 3200lbs. We expect somewhere around 8.80-8.90 at around 29-31lbs of boost. I believe you have the compressor wheel size mixed up though. The inducer side is 74mm, making it a 74 turbo, not a 91. Thats the largest available wheel of the 2 they offer.
