Rightio guys...silly question perhaps, but I'm very curious. I have a '97 HZJ80 with a 1HZ and a five speed box. It's a povo pack so no tacho. I'd like to know the revs of the gear change points I use....eg....1st-2nd at 20kph.....2nd-3rd at 40kph...3rd-4th at 60kph and 4th-5th at 80kph and finally...what are the revs at 100kph in top? It's my first diesel and I don't really have an ear on whether I'm over-reving it or not. I think I'm erring on the safe side, but want to make sure. Any help would be greatly appreciated.
