If you want an R32, just get an R32, most likely less expensive than buying a car and then swapping the 3.2 VR6 in. Even better, just buy a Bora/GTI VR6, it's the same exact engine, just minus about 40hp, again, it'd probably be less expensive to go forced induction on a 2.8L VR6 than buy an R32, you don't get the AWD though.
The R32 looks cool, but it's insanely heavy, my car is only .1 second slower to 100km/h, simply because the R32 weighs 600 lbs more.
