final and best upgrade you can do to any vw 1.8 engine (rabbits, cabriolets etc) is upgrade to an 2.0 oil pump (just ask for an 95 vw jetta or golf 2.0 oil pump) it bolts right on is about $60 from any autoparts increases oil pumping volume dramatically and will keep your engine alive for years to come.
Pros: increases volume dramatically, bolts right on
Vehicle:
Volkswagen
