Just found the forum today. Have a 91 golf 1.6n/a idi and a couple spare engines . Also have a have a couple mk4 Jetta tdi's with ALH engines that I am pulling the engines out of for future projects. Trying to find some info on the 2.8 tdi engine as they are not available in Canada. From the bit of info I can find, you can modify the pumps from the 2.8 to work on the 1.9 tdi's to turn them in to a m-tdi. Any thoughts.
