The ugly / known issues:

Needs a better clutch. I took a gamble with a stage 2 ebay clutch. It slips in 4th and 5th gear after about 4.5k rpms. Holds fine 1-3rd gears.

HLA's noisy when cold (pretty normal for an old NA actually).

Very random misfire when cruising on the highway, seems worse when cold outside. It never did this before I installed the toyota COPS, so I'm guessing one of the coils is acting up.

DIY electronic boost controller is installed but stopped working. I made a DIY manual boost controller and that has been working fine.

Exhaust manifold has a small crack at the back of the collector, doesnt seem to affect boost though.

Overall the car is in good shape for its age. It is my daily driver and has never left me stranded.
