The big question is WHAT ARE UR GOALS...
Hmmm well bit off handling and power..
1) Aftermarket
ecu- 3.5gs tuned
2) FMIC- 1.5gs
3) Turbo- 2g
4) Injectors- 0.5gs
5) coilovers 2.5 gs
Theres ur 10 grand spent in seconds.. Ud prolly need a new g/box with that setup hahaha. You could get all these cheaper if u source second hand products. Which u could use to getting a 6-speed (7gs) or dogbox (pita to drive every day)..
powerwise 200-230kw atw with a fairly steetable turbo like a 20g...
