main gearbox needs to be replaced obviously engine aswell.
looms will need changing and then theres the issue of fuel pump.
personally with both of my 90's i modified the origional underslung tank.
i love the td5's and wouldnt go back to tdi's again.
my winch challenge motor was transformed when it was fitted
and my road 90 that tow's it about was also transformed, no more mauling the guts off it, it just gets on with it no hassle.
give me a ring between 6-10 at night if you want and detailed info
