I've just recently been getting bits and pieces together for my next engine build and when it came to needle bearings, I got prices on the competition bearing and the stock bearing, part numbers are:

NF01-11-D54 Stock Needle Bearing
0822-78-184 Competition Needle Bearing (Heavy Duty as the catalog states)

The next thing is, the competition is less than half the price of a stock bearing!

My prices for these are:

$15 NZD for the competition
$49 NZD for the stock

My main question is, what are the major differences between the 2 bearings and is there any reason why NOT to use the competition bearings?

the NF01 bearings are the larger Cosmo/FD size, the competition bearings are for the older engines, which run a smaller bearing

Im thinking about having my buddy machine my front counterweight to fit the fd bearings. I need to get a fd front counterweight to copy on my s4 counterweight

That will throw your balance off unless you have FD rotors and rear counterweight

how would machining the thrust bearing larger throw off the balance?

I will be using a s4 counterweight, but thinking about having it machined for the bigger bearing. I don't think the amount of material taken off will be a huge deal

He said he had a s4, but want to use a s6 front counterweight, and machine the s6 counterweight....least thats the way i understood it
