You'll SMOK him.
I used to sell VW's. Although, the 94's were a bit lighter than later year jetta's and stuff, If his Vr6 is all stock, you should quickly and easily school him at like half throttle.
Jetta's were a bit heavier than the Hatch back GTI's with the same engine. If you were racing one of those, It'd probably run even with the SC.
One thing that I like about the VR6, it's a smartly designed engine and revs very smotthly and has a good amount of mid-range torque and high end pull. PLus, it sounds nice.
