The UR is the evolution of the UZ series. The 3UR is a 5.7l 32 valve VVTi with aluminum block and head. Stock 381 hp and 401 ft lbf. Used primarily in the Tundra, Land Cruiser, and the LX 570. A TRD supercharger is available for 504 hp and 550 ft lbf but that's a bit much for my drive train.
I've searched but I didn't find much on the 3URs. I originally planned a 1UZ swap into a FZJ80 Land Cruiser but I've come across a low mile 3UR. I know David had a couple a few years ago but I never found any dimensions. Anyone done a 3UR conversion or have block dimensions?
Anyone remember the size and thread for the transmission/engine bolts? I picked up a 1uz for a conversion project and I need to get in the engine stand. I thought they were were M12x1.75.
