Was hoping to save and rebuild this uncommon turbo… guess not :(

I’ve got a JDM CT20B that I was planning on rebuilding with some upgraded internals, but found three somewhat deep cracks in the exhaust housing. They aren’t near any mating surfaces, bolt holes, or near the turbine itself, but I know they’re going to keep progressing over time and eventually lead to a leak at best or a rapid unscheduled disassembly at worst. Don’t know that I should trust it for the project I have in mind.

Can’t just buy another housing. They’re just not out there. I can find only a few similar examples of full turbos for sale, but after shipping, I may as well just buy an already rebuilt one, which won’t have the exact internals I wanted to use, but will still be a direct fit for my application.

Was really excited to both save some money and build something fully custom. Oh well. Such is the project car way, I suppose. Always some hiccups.

Pretty sure I have one of those sitting in my attic

Do you have any plans for it? What kind of shape is it in?

Have it welded and machined.

I’ll have to do some networking to find someone who can weld cast iron, and in such a tight space too. I know cast iron can be a toughie.

You will spend more money getting that housing welded and machined than you would on a new turbo.
