It looks hard, but it's fairly straight forward. Take your radiator out, disconnect all your wiring loom. There's a couple of hard ones to get to, particularly the starter motor wiring and the knock sensor, the best way to get to these is through the driver side front wheel well. take your intercooler piping out, take your exhaust off, take the rear drive shaft out, pull your front drive shafts out. Take your clutch slave cylinder off aswell. There are a few other hoses and things to take off on the inlet manifold, oh and your air con compresor needs to be taken off... put a crate or a trolley under the car and lower it down until the engine is sitting on it, undo all your engine mounts and lift the car off of the engine...
Bit short, but if you have any questions I can go into further detail.
