NTN makes some of the stock bearings for Nissan as I recall, so that one should be good quality. Not sure about the British bearing, but I can say that it probably has bad teeth.

That's not very nice...funny though!

The RHP bearing will be ok.They've been around for years.They are high quality.I've used them in electric spindle motors that run at 20,000+ rpm and haven't had any problems.

That's great. Fortunately bearings don't need teeth! The Black Dragon kit is probably the way to go.
