Need turbo help

[dieselboy740]

im running a .48/.60 on the bII turbo it spools quick but i have creep problems. Its got a rangers revenge header though. Ill hit 20psi in 3rd. You can hardly drive the thing.

The other turbo he has is .48 on the exhiast side. Should I have picked that one up instead since I'm building this motor to put in an offroad ranger

Also, where is the best place to get forged pistons?
