o boy this will cost u a lot of money. i knew a guy doing a n/a build and it cost him a lot of money and still wasnt very fast. with high comp head work ect it will still make less than a stock turbo will make. heres a link that will show u what a ecu, intake, exhaust, clutch/fly wheel will get u..... not even 200hp.
NA Z pack its a cool idea and i say go for it, but if your not willing to spend some big money i say run away.
