I've recently completed a conversion on my 60 series landcruiser... now running a HSV 185i 5L from a VS.... my question to all out there with any tech knowledge is: Do you know what diff ratio would be best for this conversion? The motor revs to approx 6thou and travelling at 100ks it's at about 3 to 3 1/2 thous in 5th gear. It's a 83 FJ60, I think the current diff is 4.11.
