Hi,
I am sure this has been asked before but searching on the forum is not real good (even the advanced search) and it just brings up loads of completely irrelevant stuff.
My son recently went to work os and gave me his precious 80 series. We have decided to do it up and keep it. However one issue is that it revs its head off at 100km/h and after we put a turbo on it I wanted to know if we can slow the engine down a little at highway cruising speed.
1: We have to get the gearbox synchro done so while we have box apart can we get the 5th gear upgraded?
2: Alternatively do we need to get new diff centres with lower ratios. If so what is the likely ratio we have now and what ratio can we/should we change to (it is stock natural 1998 1HZ diesel 80 series but we are going to put a light turbo on it)
thanks for any advice
