this should save some people massive headaches.

if you want to use OEM nissan bearings you need to have the 2 numbers off the crank and the number off the block as shown in that link.

when you have those 3 numbers you can give them to someone who knows what to do with them and they can tell you what grades of bearings you need to use.

takes out alot of guess work.

however, this is not a replacement for plasti-guaging… its just due diligence.

Good post Bingeroo, however most engine builders worth their salt should know this. That being said, if they do not, then I wouldn’t trust them with my engine.

For anyone wanting to build up their KA, SR, RB, VQ, whatever, take it to these guys. Absolutely top notch work. Just ask people about my SR and how strong it was. www.ajaxengines.com
