hi guys! im new to this! i want do to something a bidifferent so ive picked up a mk3 1.9 tdi, as its a everyday car i want to keep actual running costs down so I have had the idea of popping the 170bhp diesel lump from the new golf in!

i know this seems pointess and a waste of money but its a bit different! is this do-able at all? any help is appreciated!
cheers
