Converting Touring to M3 spec?

The end aim of this is to chuck an M3EVO engine and associated gear into an E36 touring.

Based on:
www.fabdirect.com/index3.htm

There's a choice of a complete kit which includes suspension, or one without suspension and diff, or just the engine. My questions are:

1: Does the touring handle like a big bag of frogs compared to the other models?

2: Is the M3 suspension interchangeable with that of a touring? I assume the front is the same but is the rear different? Bearing in mind that springs/dampers etc will probably be replaced with non OEM stuff.

3: I would assume the engine and box etc are a farily straight swap? Someone tell me i'm wrong...go on....

4: Would the engine run with the standard gearbox and diff without ripping it to bits (or at all)?

As a final thing, anyone know of a garage in the UK mad enough to do the work for me as i find using a dipstick a challenging experience?
