I thought the last year for the W56 was '88 ?
The W56 was used on U.S. Toyotas through 1995. But is still used on current model 2003 Hiluxs. Toyota puts it behind the 3RZ 2.7 motor. In fact, they also still make the R151F. They use that in the Land Cruiser and in the Hilux behind their turbo diesel. The things we Americans miss out on!
