Just have to gather all the parts but you can for sure convert it back to turbo. Hopefully the other engine is the turbo engine. You may have some of the parts to convert it back if you got parts with it. The exhaust manifolds, fluid tank, air cleaner, valve covers, and turbo system can be located if you don’t have them. I have not got a quote yet for the intake. I do have a turbo exhaust manifold if you find you need one.
