Re: m20b20 reassembly...
Maybe you could solid-mount the engine/box, but bear in mind you would probably end up frequently breaking propshaft/driveshaft joints, since the rubber mountings help reduce the torque stress on these parts when setting off, or changing gear, seeing as the engine/box has a bit of 'give' and twisti...

I have another one for you :) The engine that I want to transform from l jet to motronic is m20b20 from 1985. The pistons on this engine have profile that goes deeper in the head and I assume that is why the compression ratio is 9.8:1 against 8.8:1 on later m20b20 engine with almost flat piston top....
