what I know: Turbo timer is pooched - happened to the guy who bought the car from me (I tried to help him trouble shoot, but the unit itself was hooped)
Rim size is wrong - the hub size on rims are a hair too small - they've been ground wider to fit
Cross over in fuel tank MAY not be functioning.
Idler pulley brace for accessory belt (as far as I'm aware) is broken.
Intake pipe leading to the turbos (under the intake manifold has been cut and re-glued back together - I'd look at replacing this)
Powersteering pump MAY have been replaced - it was on its way out while I owned the car
Fuel lines at the injectors and injectors MAY (should) need replacement.
I know the kid who bought the car from me - and as much as I wanted to help him with the repairs and "mods" he wanted to do... there was a LOT of hack and slash crap that was done. He unloaded the car to someone else and it may have changed hands a few times.... But this is just what I know about it.
Aside from the aforementioned challenges - it was a nice little car - just wasn't my flavor.
(and before anyone flames me - any of the issues I had with the car - were discussed with disclosure with all interested buyers)
