Can someone suggest me a better wastegate than the original unit? Which one bolts on directly without modifications? I had a track day and after a while when everything got hot the wastegate wasn't doing it's job correctly. It didn't let the gases out smoothly - boost gauge needle was moving up and down under boosts.

Orginal is good unit, and only bolt-on unit there is.

I think you have different problem, broken film inside, or more likely wgfv valve is too slow, to avoid this crank ventilation has to be modified.

I don't have a oil catch tank because the tube goes directly to atmosphere. And I haven't noticed any oil comin out after engine rebuilt.
