I have gotten my stroker crank and am working on the oil seal to make the 3.0L stroker.
I was wondering which bearings I need and the differences between yellow and blue bearings. My e30 manual shows the clearances and standard sizes of the m20 crank and my (limited) measurements show approximately the same values.
Main bearings ~59.99 mm
Rod Bearings ~25.0 mm
I have read about the early and late bearings having/not having the oil groove in them, respectively. Apparently the m54 crank I am using had the same oil groove used on its application.
So should I use early or late style bearings?
Thanks!
