Hi, I've recently been looking into the TD04 conversion. Seen all the manifolds, downpipes etc from WEPR (any good?) and the turbos aren't too hard to get hold of. Now before I even think about buying any of this stuff, what should I do engine wise to ensure everything is running right. At the moment its all standard. I'm after a basic list list of things that will need to be changed/uprated for the conversion. Ta
