Mods-Drivetrain
The only thing not stock here is the clutch; not sure of the brand but it is a ceramic disc clutch (so I’m told). It’s a bit heavy but clamps like a champ.
Mods-Handling
Poly bushings all around except motor mounts.
Parts Wishlist
I wouldn’t mind getting a set of reputable coilovers for the car, such as Feal Suspension. Maybe some stiffer anti-roll bars too. I have a Jay Racing alternator relocation kit I’d like to implement but my damn alternator bolt is seized in. Also have an Apexi boost controller that isn’t hooked up but I think I may wire in the solenoid directly to the ECU. The software should be able to run it through the factory BCS wiring.
Background
Bought the car not running in 2013. The car was undergoing too many mods at the same time and I believe it overwhelmed the previous owner. Got it all figured out, brought it to a tuning shop where they ironed out a few issues and got it tuned (not great but good enough). Like to make 300-400whp with it some day, I believe most if not all of the supporting mods are capable of it.
