Hi guys im new to this forum, thinking about putting a VR6 lump in my mk3 TDI and need some advice. i have a mechanic friend willing to do the job, but he needs to know how much customising will need to be done regarding the swap from petrol to diesel. i want to buy an engine and all ancillaries, so i need to know exactly what i'de need to buy and how easy or difficult it would be for my friend to fit. some of you are probably asking 'why not just buy a regular VR6', its because ive been given the car, and then i wrote it off in the snow, then i managed to fix it, and now i want to put a bit of money into it to turn it into a sleeper as i have it looking just how i want it. hope this message kinda makes sense and i thank you all in advance for any pointers or advice!
