Diesel diffs will help slightly. Petrol ratio is 3.9:1 and diesel is 4.1:1. So not a lot of difference. Safari spirit II 2.8 diesels have 4.6:1 but are hard to come by. Every one is looking out for a set. Or you could go after market ring and pinion, just a bit $$$.

Not all petrols are 3.9. I think only efi auto's are and the rest are 4.1.
Check transaxle code and it will be either HG 39 (3.9) or HG41 (you guessed it 4.1)
