i bought mine last June and Ive driven it everyday since. Except for one day when i broke my Wastegate.*shrug*

Commonly breaks or malfunctions?

Rust (limited number were produced so alot have rust)
Injectors
injector clips
Dirty gas tanks
Cracked head (around 3rd cylinder)
split intercooler pipes
stock MAS is poor
Power steering gear box is crap(not a rack & pinion setup)
sloppy torque tubes

I swapped my built motor in about 3 weeks ago and it drives beautifully.
