Was donated a spare engine mount and treefingers kindly pointed me in the right direction of how to modify the mount to fit to the 20v engine. Ended up with this...

Modified the alternator bracket to get rid of air con compressor and power steering pump mounts. Got a smaller belt to run just an alternator. And a manual cam belt tensioner.

Stripped every cable, wire, hose etc from the old engine and removed all the excess from the old engine loom.

Still halfway through here. But you get the idea.
Once the engine was out. Removed the gearbox and flywheel to fit to the 20v engine. Bolted it all up along with my newly butchered engine mount. And dropped it in.

Fitted a slightly larger than expected Mercedes sprinter intercooler. I probably should have measured one of these before I got this one. But it was cheap. And it does fit. Just.

The radiator will go between this and the engine, but am going to need a slim fan.
I have a fuel filter and bosch 044 fuel pump that is going to be fitted to the inner wing on the drivers side of the car.
Have still got to plug the loom into the fuse box and ecu, connect clutch cable and speedo drive, figure out where my boost hoses will go, bolt up driveshafts and get the downpipe to meet up with my exhaust. Probably a few other jobs I've forgotten to mention, but have made a decent amount of progress at last.
Ben.
