Any further progress with this?

I'm really struggling with engine choice atm

1.8t - easy to source/fit but don't sound fantastic
2.2 20vt - not much harder to fit but getting hard to find bits for. Sound better though
v8 turbo - easy to source engines here but I don't know much about them. Conversion kits available.
volvo 20vt 5 cylinder - hard to fit but cheap to buy
audi v8 - lots of work
audi 07k engine - engines stupidly cheap but fitting is hard. Take stupid amounts of power though even as stock.
zetec 2litre - not seen that done but if one sounds like a old rs turbo then i'm interested.

So far I have both a 2.2 20v engine and a v6 s4 engine. I'm waiting for a friend to come give me a hand collecting a 07k engine but that might go in a different car. I'm leaning a bit towards the v8 or 1.8t.
