Happy Thanksgiving !!

I have a high mileage, non turbo B230 engine in an otherwise good running 91 745 wagon. The rear main seal is leaking. The engine runs OK but I have heard quieter.
I also have a sweet running B230FT engine that I am about to pull out of a 92 wagon with a bad tranny. I have other plans for this wagon which do not use the original engine or tranny.
Logically speaking I should drop the tranny and replace the seal and I understand this is a bear to do. It might be less work to swap the engine seeing as I have one. The turbo engine has no leaks and sounds nice with minimal piston slap.

My question is: Can I put the turbo engine into the non-turbo car if I swap over the exhaust manifolds to remove the turbo? The engines look the same otherwise.

I suppose I could swap all the rest of the turbo engine stuff over also but I think this would be quite a project. The non turbo car is Regina and the turbo car is Bosch. I actually intend to sell the car but I am thinking this would be tough with the rear seal leaking.

Thanks for any opinions, feasibility etc.
