I am in the very early stages of a prerunner build, planning and financing stage really. But anyway I'm looking on ways to squeez out as many horses as i can from the 1kz in the Surf as I wanted a surf because of this engine and dont plan on changing it. Open to any suggestions

Hello friends,

Just pulled the head from a 3.0 1kz as it was smoking grey/white and pumping water out of the expansion tank, the car is a Regius. I bought it like this after previous owner overheated on the motorway and found blown radiator, they had a new radiator imported from Japan...
