a239947 Posted 11April, 2019 Report Share Posted 11April, 2019 So I sent my turbo in for a rebuild as part of my engine refresh. Turns out it has a few issues. It has a cracked turbine housing which has been welded and cracked again. Pretty much all these housings crack. but i need one that hasn't been repaired and cracked again. Also my bearing housing seems to have a piece thats broken off it. Which means that need to be replaced also. To top all that the turbine to housing clearances are too big and needs a re-sleeve. but they cant machine the rear housing without guaranteeing it wont come apart because of the cracks. So my question is. Does anybody out there have a Turbo for a series 2 924 lying around that they are willing to part with. It seems any of the wreckers here that have them want me to mortgage my house for them with no guarantee of condition. Any help or leads to helpful people would be appreciated.

Uncle Posted 12April, 2019 Report Share Posted 12April, 2019 For the love of god why would you put a factory turbo back on it? Link to comment Share on other sites More sharing options...
Coastr Posted 12April, 2019 Report Share Posted 12April, 2019 ^ This does seem like a reasonable question. A new turbo would be better performing, have parts availability and most people would never know the difference. Maybe it's hard to match the housing / manifold for new turbos? I get the originality bug but nobody thinks twice about upgrading a clutch or muffler - how important is it? Link to comment Share on other sites More sharing options...
bear924 Posted 13April, 2019 Report Share Posted 13April, 2019 The challenge with the 924 turbo is that the exhaust manifold is a three bolt pattern, where most turbos are four. A different turbo isn't impossible, however will require some thinking. Link to comment Share on other sites More sharing options...
brian in buddina Posted 14April, 2019 Report Share Posted 14April, 2019 Did anyone do a custom 4 bolt turbo manifold 40 years ago? Link to comment Share on other sites More sharing options...
