It will definitely be good to run... these engines are so robust! I have been known to swap internals from junk yard engines to another and stll manage to hold great compression and power. NICE WORK RED!
thank you for making these videos. I bought an 85 z31 with a yucky engine and seeing you break this one down gives me confidence to do it myself! (just subbed, too)
you are correct not the way to rebuild this engine, Nissan made this engine without a balancer shaft, the components when assembled at the factory where balanced at the time of assembly, the only way to have this motor vibration free is to duplicate how they balanced this motor during assembly at the Nissan plant, and figure out how they do this, otherwise your motor wont be balanced correctly for all the diyers out there, if you do this it will be out of balanced and fail before its time
I have rebuilt lots of motors from little 2 strokes to car engines to big cat diesel engines. I have not had any problems of motors "failing" because they are out of balance after replacing pistons. In fact non of them have failed at all.
