Hi guys, thanks for your replies. I actually ordered from that sipracingmailorder website over a week ago, but it hasn't been processed until today and I don't even know if they are alive, so I'm about to cancel that order.
I asked the guys at 240sxmotoring if they could get them for me, since they list KA and SR bearings, and they say they can custom order them from me, which would be my next option I guess.
Since I am not in the US there isn't much available locally. Just hope I don't have to get anything else than STD. My mechanic isn't too confident on going with oversized bearings and cut crank, due to the local machine shop tech.
Heck, I was even going to call the nissan dealer to see if they would carry OEM bearings.
