I have a VW Golf MK4 TDI (90BHP) and just before the X-mass i want to give myself a present by buying a second hand GT TDI engine 150BHP and the engine code is BKD i guess its coming from MARK 5. Just want to know if garages will be able to do a replacement? If any one had any experience in that please let me know because I'm thinking of buying that engine tomorrow so it will arrive before the X-mass. Thanks in advance
