bnr#@ Posted November 3, 2006 Share Posted November 3, 2006 I’m about to start putting back my engine (RB26) and was wondering what bearings I should be using. The other parts in the bottom end rebuild are as follows TOMEI 86.5mm pistons Standard rods shot peened resized and polished TOMEI reinforced rod bolts Standard crank with extended collar N1 oil and water pumps Trust sump extension ARP main and head stud kits NISMO 1.2mm head gasket Final power output I’m chasing will be 300awkw if that matters Any experienced feedback would be appreciated Link to comment https://www.sau.com.au/forums/topic/141655-main-and-big-end-bearings/ Share on other sites More sharing options...

DVS JEZ Posted November 3, 2006 Share Posted November 3, 2006 im goin acl race series.... hey buddy, i just put some new bearings in my rb26 today. im running 416awkw but had to do crank collar and sump baffle etc. ACL black metal race series bearings. they dont look as nice as normal bearings because they dont get the final stage of treatment where they flash coat them. this improves the bearing to housing contact giving greater heat dissapation, also to prevent any flash plate migration or movement, and improve surface characteristics... cheers Jeremy Link to comment https://www.sau.com.au/forums/topic/141655-main-and-big-end-bearings/#findComment-2640076 Share on other sites More sharing options...

I thought that the ACL race bearings were tri metal bearings which I was told were not good for performance application?

nemini90 Posted November 3, 2006 Share Posted November 3, 2006 If you want to do things right get nismo bearings you buy them to suit the crank and block so it will remain factory iv got them in my motor and would not ues anything else if there good for a gt500 car then there good for me...

Denver Posted November 3, 2006 Share Posted November 3, 2006 all bearings have sizings, ACL is the same as nismo, well pretty much the same, might find a few microns in difference in sizing.. i ran ACL mains, and nismo big ends on my car tho, had no hassles, will probably do the same when i need to..

bnr#@ Posted November 3, 2006 Author Share Posted November 3, 2006 Once the rods have been resized the grading numbers become fairly irrelevant though don’t they? My understanding was that you get a standard size bearing and then have the crank ground to get the desired oil clearances. I have no problem forking out for the nismo stuff but the differences in bearing grades on them are measured to the thousands of a mil and I don’t think there is mush that can measure you’re crank and rods that accurately is there?

T04GTR Posted November 3, 2006 Share Posted November 3, 2006 anything. acl 780's, race series, king, all meet the stock grade. regardles of power oil suply problems kill bearings not the bearings themselves. and for referance its sr20 bigendds and vl mains.

Faid Posted November 4, 2006 Share Posted November 4, 2006 Well i used ACL and no problemo so far, they seem to handle the abuse, but a bearing will function only if you treat it good ie systematic oil changes, dont overheat you engine etc. but the ACL's are good.
