My ST165 I bought with a Supra CT26 on the gen 1 motor is pretty worn, even though it was boosting fine the wastegate flapper might have fell out of the exhaust before I took off the turbo and found the housing was cracked along with a lot of shaft play. Would it be better to go a custom wastegate flap and rebuild the current CT26 or get a CT20B or a different CT? I don't want to do a ton of custom work got a aftermarket turbo I can't really afford, so I'm looking at either rebuilding my current turbo or getting a different CT turbo that just bolts up.
