Turbo sizing

Run a 67/66 turbo. Listen to the guys at stage 6. More 1000+ horsepower turbo cars come out of there than anywhere in the gen3 world. Get some mild work done on the heads. Especially the exhaust side. I can spec a cam for you. Should be easy enough to make 450 - 550 wheel on a stock bottom end at 7-8 PSI. A 6.1 would do better than a 5.7. They heads are the big difference. A little more compression.....we run 7.5 PSI on the 6.1 and make about 600 wheel.
