Hi everyone, i know I must be the 10,000th person whom has asked for advise on this topic but I want do it once and I want to do it right. I have a 1998 mk3 cabrio 2.0ltr 8 valve advantage it's in fabulous condition but needs more omph, so I've bou a scraper A3 1.8 20valve turbo, the engine has an AGU code and I have everything I think for the project, keys, Ecu, loom, key transponder, pipes etc. So as mk3 golf has a cable clutch and the 8 valve gearbox it not equipped to take the power of the 20vt, I've been informed that the best conversion to a seat cable to hydraulic gearbox. I know the code of the box is 02j but which model seat would it be from and what year? Also the gear linkage what car would that be from. If anyone has completed this conversation I would appreciate a step by step guide perhaps with photos and list of what parts I would need for the full conversation. Thanks fellow dubbers. Any advise how ever little would help.
