the motor is in way better shape than i first thought. were i to keep this motor for myself i would pull the rotating assembly, polish the cylinder walls, replace the bearings, replace the oil pump (its within spec,according to the fsm, but id replace it anyway), and the timing set (the timing set looks ok but its a nissan and that shit is made of plastic). according to the fsm all the rod bearings are within tolerance and as far as i am able to tell without taking the thing completely down so are the main bearings.

you could rebuild this thing yourself, or if you have giant brass balls use you could throw it together and see what happens (personally i want to keep it, throw everything together, put it in a car and see what happens, but thats me). if you want more pics let me know. if your even remotely interested you should come by and have a look, i cant take pics that do it justice.
