Yep you could buy a complete 2.0 16v abf mk3 for less than 500, and there's everything you need for the conversion, including better gearbox and hydro clutch etc. Labour costs are the most expensive thing on a golf, so if you can do stuff yourself you can make an awesome car for a good price.. If you have to pay 600/1200 for a 110bhp 8v engine to be cleaned up then its bad times I'm afraid!!
