So here's the update on the AMG engine transplant so you guys & gals don't have to go thru the hell I did. First off, manual transmission with the AMG engine is a major problem. The bolt pattern on the crankshaft flange between the two engines is different and a new flywheel / pressure plate from a 2006 C230 Sport Coupe must be used, this is the only flywheel I have found to have the 4+4 bolt pattern that is used on the SRT6 crank. But the flywheel must be modified slightly because there are three dowels that align the pressure plate to the clutch cover and these are different from the OEM. You could use a clutch from the C230 though and this would solve your problem, but I had a SPEC clutch that needed to be fitted...

More gruesome details later...
