What size tyres? What motor? Auto manual? I got a turbo 2.8 and was running 4.56 with 33s and use to get 100kph at about 2500-2750rpm

there is a few different ones that came out. i don't know what ozzie got as standard. eg some diesels came out with 29" tires and 4.3 diffs while others where 31" tires and 4.56 diff.
if you think the diffs are stock then find the diff code on the plate on the firewall. there is several lists around on the net that will tell you what ratio it is. just be aware i found one list to be incorrect on some of them.
