i bought a kit off ebay. came with a 150 psi pump. basically a sprayer pump that can be bought at princess auto. sureflo i believe its called.
still haven't installed it, but the best way is to pull off the top piece of the 1.6TD manifold, and then drill & tap for the fitting. which is already done on mine. when i get it running i'll let you know how she goes. i'm hoping for at least 10 hp gain or more depending on fueling :twisted:
some people advise against injecting pre-turbo, but hillfolk'r has been doing it for a while and hasn't reported any damage thus far. just remember that if you inject post turbo, to have more pressure than boost pressure. not sure if a washer pump can put out enough? maybe with a misting nozzle or something...
