my 2.0 is quite fast really, i havent done anything to the engine tho it just got an exhaust (lack of cash) they are not as tuneable as a 1.8T but the engine sounds much more grunty thats for sure 
That's the first thing I noticed about the 1.8T, the engine is very quiet & doesn't sound very sporty..... My BMC soon sorted that out , though!
