its a smallport. stick with the supercharger setup. its not really a question of 'just going turbo', theres a bit more into that then there sounds, and its a fairly pricey exercise (if u want to do it properly). you will break gearboxes running 14psi through a SC, i have fucked 2 on 11psi. hence why im doing the Wbox conversion. but it will run fine with a t50 if u treat it nice.
