where is the best place online that i can get oem or almost as good engine stuff.

Like Connecting rod bearings, Main bearings, seals. and piston rings.

I have to rebuild my bottom end and i want stuff that fits and works well.
I have a friend that is rebuilding his B18C , with B16B head. he ordered in connecting rod bearing and main bearings and he got them installed and the guy that was doin the building told him that the crankshaft is not turning with those bearings. so before i go and order bearings for my B18C and then my crank shaft doesnt turn then i wanted to kno where is the best place i can order them online.

 

Go OEM

Oh i am also looking for D15B VTEC connecting rod bearings. does that same place have them?

 

Nope, those sites are for USDM parts.

I think you can use D16Z6 bearings.

 

you have to have your block apart to order the bearings. there are certain ones you buy for each cap, its marked on the block
