im currently building a gsr bottom end with eagle h beam rods, wiseco pistons and a ITR crank. which would be the correct OEM bearings to get? because honda has all sort of different colors for each different clearence. can anyone direct me in the correct way??

Also looking to build a bottom end, would like this info as well.

 

You engine builder can tell you which ones. Since you are using a different a crank, you need to have everything measure to make sure they are in spec.

 

Yeah, you need to have each journal mic'd. A machine shop can let you know.

 

Ok this must not b common knowledge so.. the ITR and GSR cranks, rods, and blocks r exactly the same. So u can use ACL GSR bearings or decode the block/crank bearing code and use OEM honda bearings or u could use Clevites for a GSR or Type R or whatever u preffer. I like the ACL race and OEM honda myself.

 

ye never mind i got it..im using OEM bearings. i got the chart that determines witch is witch.
