I got my timing kit and water pump done at Nissco in bayswater(along with all the other work on my cars). Randy is a good honest bloke, call him for a quote, say Ryan referred you, and see how you go. Cant remember what it cost off of the top of my head, but Randy has over 30years experience, and he has worked on my Stagea, Datsun 1600, my gf's Supra. 9761 4743
If i didn't go there, i would try and get into RacePace.
