to make 300 hp on a 1.8t it takes a 3500 dollar upgrade kit, for 2500 you can having a turbo kit for VR6 that makes the same or more. Plus a VR will not blow the number 3 rod out off the block at that power level. With a GT28R kit you could probably pull an evo, but that is no cheap kit. Get an MK3 VR, if you haven't driven like an ass, and your record is clean, your insurance might be cheaper because the MK3 is a little less valuable than the newer car.
