I now have my turbo project motor all torn down and am awaiting the lower cr pistons, so in the mean time what should i do? What are some of the standard replacements and upgrades that i should do while i have the engine torn apart. I know about the bearings, but im sure there are more things as well. I have the obdI m42 from a 1994 bmw 318is. This also might be a good sticky for people in the future with their engines torn down. It would be a good place to go to find everthing in one spot.
