It is VERY tedious job, take that rear black bracket off (2x12mm) you see in the pics and jack it up under the drain plug, then go from the front and try to guide it in BY lifting it AND pulling it in (rear needs to hang). Also try to bend the dump pipe a bit if you have any abnormal clearance issues. Also make sure to twist the tranny where the top of it goes towards the driver's side wastegate and the starter hole is right on the pass. side one. You will see what I'm talking about once you get there. Good luck and get a helper if you can. I'm sure that would have made a diference in my case.
I have the High Res. version of the pic's. I can email you them if you prefer.
