the turbo block also has piston oil squirters to cool them.

the head has neat stuff like sodium filled exh valves.

the 83 5kt uses exactly the same fuel management system as your coupe

I would say the real question you should ask is, how far up can that 130
hp be bumped?

and if you decide to wait for an MC, you could always just snag the cam
from the turbo and put it in your engine...
