not much...
If your plan on modding up a stock 2.0 block your in for some heart break buddy. Mine blew a rod bearing at 81k and with bolt ons. Best bet with an 02-03 bugeye is to do a 2.5 swap. Then after you do that and mod the shit outta that motor, prepare to be fixing the glass box transmission thats on there. I donno ive gotten pretttty lucky with my cars tranny.
