Just want to know which would be faster in a flat out 0-60, and a 0-100mph. I know the VR6 is more BHP, but those heavy mk3s ain't built for speed are they? 
0-60 you'd find yourself entering the realms of despair (if you're the 16v driver that is), as the VR6 would have a few feet on you.
somewhere between 60-80 despair becomes frustration, and between 80-100 tears well up as you realise there is nothing you can whatsoever and you just got trampled big time.
so there you have it. dont race a VR6. if you do, pray they miss a gear change. or two.
UPDATE: in fact - pray they have a totally buggered gearbox.
UPDATE2: and engine.
as for going round corners - there wont be much in it. they both feel like crates, and you'd be had by anything that is mid engined.
