In the UK, it'll be a 1.8T gas, 2.0T gas, 3.2 gas, 2.0 Diesel, or 3.2 Diesel.

I'd only worry about the 1.8 gas and 2.0 Diesel. Everything else should feel fairly gusty. One may yeild faster acceleration times, but they are all tuned from good mid-range punch (around town power). You'll likely be very satisfied with the 2.0 4cly turbo.
