Just done this conversion myself. I put a 1995 td engine into my 1999 van. Didnt go so smooth. for some reason, it wouldn't start on the key. You have to splice into the loom. What i done was fitted a start switch to bypass this problem. Another thing is i have found the intercooler is v close to the underside of the bonnet. i got a vent to go in soon but in the mean time i have lifted the back of the bonnet 30mm to help with cooling. hope thats some help.
