Wondering if this would be a good swap to a '93 12v with some minor tweaks:

Cummins ST-50 turbocharger. Both blade wheels fine, rotates freely, no noticeable play- seems very good cond. . Bought for project that was cancelled!

They want $250 for it...

 

I don't know for sure but I think that is going to be way to big for your application. It might work well as the bottom turbo for twins.

 

That's what I needed to know, thanks. Still learning....
