No number yet for me... still putting everything back together. But im going with 408, GT91 T6 turbo, 4L80e from Jakes, most likely a 3.25 rear gear, and fuel is going to be E-85. Still need to talk to some of the sponsors on an adequate fuel system for E85 (most likely FIC 2000cc's and a large pump), but i wanna run 15-18lbs on the street and 20+ at the track.

Boost is restriction, your looking for a certain CFM. Use that to match the Turbo you need.

GT91 Turbo from Jose at Forced Inductions, 1.08 A/R.

You will DEFIANTLY want to run Methanol, since you're not running E85.

The GT91 is $1600.. It will meet your power goals. And you can always change the exhaust housing. You don't have to change the turbo.

Look into Bell Intercoolers or one of Shearer Fabs Intercoolers. Any good core 4"+ Thick would be nice.

Also 20-22 lbs on 317's will be close to lifting point. Be careful either way. I've been researching and the consensus is 16-17 lbs safely on stock heads
