If you're familiar with the 4G63 then it's probably a fine option with sky is the limit power like the Audi 1.8t 20v it earlier VW 16v with a turbo. All have been over 1000whp.

I also have some background with DSMs, and as much as I love the 4G63, I don't see it doing well in this application.
1.) I dont' think the cam gears would fit under the hood without a severe lean to the engine
1a) I'm not an engine designer, but would there need to be special considerations beyond a custom oil pickup/pan?
2.) The waterneck is on the wrong side of the head; it would need a LONG water pipe. Doable? Yes. Preferable? no.
