I've got an old CarTech turbo, manifold, and carb kit including rising rate fuel pressure regulator that I'd part with. You'd most likely want to rebuild the turbo and rework the carb as it hasn't been on a running vehicle for 15 years but it is complete. PM me if you're interested.

In a word? Custom build.

Some of your questions/issues will be:
1. exhaust manifold - to mount the turbo + downpipe
2. blow-through vs. draw-through if staying carb'd (Nikki, Weber, Holley, etc.) OR injected + appropriate fuel supply
3. locked distributor vs. timing-only computer (if not going full fuel injection)
4. intercooler (custom setup)
5. clutch

Not locked distributor but limited advance instead. From 0 to 10 degrees max.

Thanks, I actually made this thread before the swap thread lol. But im guessing this would be easier than a swap. But I'm not quite sure how to do any of this. Could I buy an exhaust manifold or do I have to have one custom made

No worries. I honestly didn't look at the two dates.

12A Turbo threads

If my memory serves, Coldy13 had a fairly NICE build, so I would imagine his build will be on one of those pages.
