RB25 Bearing Questions

[B33st]

Ok i know this has been talked about a lot already and had been established that ACL sr20 rods bearings were the ones to use with RB30 mains.

I have just looked at the race series product listing from acl.com.au

and it now shows a listing for the rb25. Rod bearing have the same part number as the sr20 ones but with the mains bearings they list different part numbers for the RB30 and RB25. Any Idea's

Also both sets for the rb25 are the same as what they list for the rb26, just larger oil clearance?

RB30 mains are different from rb25 items.

I ran King bi-metal race bearings in mine. Its done 16,000km's and still running strong.

Their Download section has lists for interchangeability.

i.e Clevite, acl etc..

RB30 bearings will fit and work but are fractionally narrower.....use the rb25 ones if they have them now
