Does any one know a good DIY on removing an M20. I have been looking everywhere and have yet to find a good descriptive DIY. It would also be nice if there were pictures. Thank you for the help

Removing an M20?

The Bentley has pretty good coverage of it. Basically, you pull the ECU wiring harness out of the glove box through the firewall. Then disconnect everything that connects to both the frame and the engine. The wiring harness can come out with the engine so you don't have to completely disconnect it while the engine is still in the car. Either drop the driveshaft and disconnect the shift linkage and clutch slave cylinder and then pull the engine and transmission out together or drop the transmission separately. It is up to you.
Make sure you drain the coolant out of the block or you will be drooling coolant all over the place when you pull the engine.
But anyway, the Bentley is a good bet.1987 E30 325is

it's really very straightforward, and much simpler if you remove the transmission along with the motor. i even left the fan on mine when i pulled it all. disconnect all of the obvious big components, disconnect the DME from behind the glovebox and pull it through the firewall, o2 sensor, shifter components, fuel lines etc etc.

This sounds lame. But swapping engine(m20) is like riding a bike. once you learn its easy as pie.
You create a checklist in your brain after a few swaps....guibo,shifter,motormounts,wiring,exhaust, radiator,etc.........sigpic
