If anyone has done a TDI conversion on a gas engined car? What kind of cost and electronic headaches? What rpms is the TDI happiest? I've found a vanagon specialist in Canada that does conversion harnesses. It wouldn't be hard to equal the 130 hp that my 10v 90q has and should get 40+ mpg plus 170+ lbs/ft. Feel free to contact me off list. Dave.
