You should just pull the 22RE back out and go get a rebuilt turbo engine and put it in. If all the turbo EFI system is still there, the 22RE is not going to run right with it. That's a good price so you should be able to get the right motor and put it back in. Is there any turbo at all with the truck? Getting a rebuilt CT20 turbo will be expensive and if you don't have a core that will add to the cost. Get the turbo if he still has it. I ported out the exhaust manifold and turbo housing on my old 87 4Runner and that thing ran great with a new turbo on it! They're a fun engine, but they get pricey real quick.
