I have NEVER started this engine, I dont know what it is like. I havent used the gearbox so again no idea on condition. It came from a TA63 halfcut that was minus the dash cluster. It looks clean inside the filler, no sludge build up at all. It does not smell like it has been over-heated. It came from a car that was sourced in the snow regions of japan and with that snow/salt it has external corrosion which makes it look not so pretty however that is merely the external appearance. For all intents and purposes I feel confident it will prove to be a reliable engine but I have nothing but my experience with basic inspections on engines to lead me to that conclusion. It could ultimately prove to be incorrect but thats just the way it is with import engines no matter where you go. Because of this I am willing to let it go cheap.
