finally got some time to look at the parts needed for the 4k, We are going to need a clutch setup and flywheel from a 5k turbo ( 200) or simular car, Also need timing belt and waterpump for a 91 200 ( mc2 engine) as well as both motormounts for a 85 4k. Once I have these I can stuff the motor. I plan to put the engine in the mid Nov. After I am done with the Dunebuggy and Bugjam.
The stock clutch and flywheel will work on 5-8psi boost but not much more, So if we can't find a flywheel a stock 85 4 k setup will work
P.s stock is a 228 mm and turbo 240 mm

Rudich knows where to get the best deals on old school parts.
