Buy a 4agze. Disassemble, true everything up, replace consumables, buy a twin screw charger from c4ag (I think), add a turbo, throw some cams at the motor and pump 35 psi at it. You'll want a T-101/GF4a and a explorer 8.8 or something to hold the power. That'd be what I'd throw together if I had the time and money. : )
