All right. now i has been driving the 19J setup on the 200tdi for a few month now. It seems a lot better now. I've been turning the turbo a bit up by two turns, shortening the link. It runs werry well, same speed compared to other normal 200tdi's. There has not been any problems, so far the last 4000 miles so i think this is at any stage the easyest way to convert a LHD defender. The turbo sounds as it is supposed to, and it dosnt sound like its overloadet.
I strongly recomet this steup as an alternative to the modified exhaust pipe.
Thanks for the nice replys. Claus
