? for STS guys I'm new here, but have been reading up on this site for a few weeks. I am doing my first f-body build and have a simple ?, I hate asking the "what mods for what hp ?'s" but this isn't exactly one of those.
I have a Callies 383 9.0:1, fast 90mm intake, a custom Bauer turbo cam (getting ground now, no specs on it, but lifts should be upwards of .600, 114lsa), Dart 225 heads, Pacestter lt's, and FMIC. I had been considering just the base STS kit, but I want to make sure it can put down the numbers I want. Should I look to upgrade the turbo to help make ~650whp, or will it be capable of it on it's own?
TIA,
Adam

With that "low" of compression and the bigger engine, I say go for a larger turbo. I'd hit up the 70 in case you wanted to upgrade down the road. According to EPP (I believe), the t-67 maxed out around 13.5 psi and they made 700rwhp with 9.0:1 compression...plus all the interal goodies that go with a nice engine rebuild/overhaul...

I have a 67 and hate to lose all the money in doing an upgrade. Ill probably stick with 600-650 hp for now. I may spray a little nitrous on top of the turbo tho.
At the 600-650hp levels what times are the sts's running? It seems they run a little slower than most 600hp cars..

Don't play around with the small turbos on that size motor. Go straight to a .81 T76 GTS, ditch the long tubes and put stock manifolds back on it and the car should run good.
Why such an extreme cam? Even with a T76 your shift point will be about 6000 rpms on that size motor. Stock cam or a z06 cam would be much nicer to drive.

What I have listed in my first post is my guesstimate of where I think it might be at based on what I wanted from the Bauer guys. I asked for decent manners but to take advantage of the heads, so it'll probably be a little smoother than that. I should have the exact specs on the cam very soon and I'll post them.
BTW I appreciate the input guys.

thats a smaller turbo in your sig.. is it a multidisc? If so I would assume you have a trans brake?
Your running stock ported and coated manifolds?
Has anyone tried shorty's or mids? Just rather have them if they will work well?
