I'm still trying to decide on what diff ratio to use in my soon to be 1UZ and stock Crown auto Zephyr ute. Maybe I should look at it backwards. Has anyone settled on what is the best crusing revs (100 kph) for the 1UZ. My car will mainly be doing highway klms, but at the same time I don't want it to be a slug around town. I read an article that said at cruising speed, having your motor revving too low is not good for the drive train. Based on the calculations so far, my ute with 9 inch and 3.0 :1 ratio will be doing about 1800 revs at 100 kph. Wouldn't the motor be labouring at these revs? Acceleration would be poor as well, and hopeless around town. I read on another thread that low revs doesn't mean good economy either. Each motor has its ideal rev range for power and economy. Any suggestions? Kevin
