I have a mk1 golf gti campaign1.8 and access to a 1.8 turbo engine with ko4 turbo at a reasonable price the thing is i need to know what needs to be changed/modified to get the engine running in the mk1 (i dont think getting the engine in should be too much worry as the blocks are near identical) any help would be much appeciated its just i dont want to get the engine and not be able to get it going without great expense.
