There are two gentlemen out there who have hung turbos off of C-14's: one is Spasonaconcours (I think his real name is Dustin) and I cannot remember the other one's name or handle. Dustin ended up munching an engine due to the fuel pressurization diaphragm giving out but I do not remember either one of them having any trouble with the clutches, or making any huge mods.
You could do a search of this forum as well as Google of course.

I love it. The good news is that complete motors are about $800 on eBay.
