on an unopened factory stock engine and trans running on pump gas (with a TurboTweak chip), the factory stock turbo is where you want to be. the factory Garrett TB0348 for 86-87 is fine for up to 20-22 psi - no reason to run anything else on a bone stock engine. TA49 (TE44) does not come into its power range until 24-26 psi boost and would give about 20 hp over stock at 16-18 psi. TA49 would work fine with stock converter.
maybe you can work out something with Timinator for a stock turbo.
Limit had a lifetime supply of (good, used) factory stock compressor wheels, covers, etc from the cores they took in for decades. I expect all that stuff went to Mike at Work Turbochargers. Bison too has also done a lot of work for folks making something from good, used parts that he's stockpiled from cores and trade-ins.
So, I'd get more info from Timinator re: what he has and I'd talk with both Mike at Work and Bison about building a stock turbo from your damaged unit as well.
I have a few spare units for my own car, should I ever need them. Suggest you have a spare as well.
