No clue lol... old engine probably had quite a life. Also these days it would be heavier crank, maybe better pistons.... back then it would have been mostly the same on both except the turbo version likely has jets to flood the bottom of the pistons, a bigger oil pump and larger exhaust system. This can reach full oil pressure at idle while feeding the turbo as well so no issues on oil supply....kinda curious, if it was supposed to have had a turbo (TW..) where did the original one go ?
hmm, would there be 'special/better' internal parts for the turbo version
just curious......
So main thing I need to watch is the EGT
