yo I had a b18c1 turbo motor built years ago and it spun a bearing, I took the crank out and it is labeled B2. I think the machine shop put an ls crank and rods in the first time now I was gonna put a gsr C3 in but I dont think the rods will work? does anyone know what the stamps mean?

thanks

 

Those numbers and letters are used in conjunction with the letters on the block to identify bearing colors.

 

well in that case do you know how to distinguish the gsr from the ls and the bearings I bought are standard acl will that make a difference with the cranks being numbered differently?

thanks

 

look at your rods, that will tell you what crank you have since rods match the crank.
