I've always wondered this, but could never find an answer. Early model 1UZ's have 250hp/260tq, then in 1997 it got bumped to 260hp/270hp, and then again in 1998 to 290hp/290tq. I've always wondered, what it is that they changed to increase the power on the 1UZ.
95 was the introducing of the semi-refreshed design of the 1uz...they tinkered with the heads so it could make a little more power hence the first year it was a interference motor. 98+ i believe had introduced VVT-i which bumped it up to 290hp.

Wait, you're telling me the 96 is an interference motor? Damn I thought that took place when they put VVT-i.
