Turbo kit was around $4000nzd, which is alot cheaper than other places are selling them for (i have seen gt-rs kits sell for over 4g), then add atleast 6g nzd for all the supporting mods, thats exhaust, cooler, fuel system, ignition, clutch, etc etc, i could have done it alot cheaper by using cheaper parts, like custom steel exhaust, cheap chinese cooler, cheap fuel pump, etc etc, but i chose to spend a bit extra and get things that fit perfect and have been proven plenty of times to work, it could be done alot cheaper if you wanted though.
