Rebuilding, Need Help/

[maka]

Hi guys,

been posting stuff on WA forum, but just thought I'd ask everyone.

Still rebuilding my engine, but now I have come to a point where I am stuck.. I got my Pistons all cleaned crack tested etc.. and same with crank and the rods.. But I am now tring to find bearings and rings.. They are all standard size, according to the machinist.. I have called up Veale's and they have ACL race bearings for standard size. and piston rings to suit.. But then I called Xspeed, and the guy told me that the RB25det has 3 standards, and the bearings etc need to be matched etc etc.. Has anyone heard of this, or is anyone aware of something like this.. Where would you get your bearings and rings from??

Its just an RB25det, with all stock pisons etc.. was complete, but I honed the bore, and decided to get some new parts..

Cheers guys.

Maka.

I'd trust your machinist mate, I'm sure he's seen a bearing before.

ACL sell 3 sizes of bearing, standard, ten thou over and twenty thou over. might have been what the xspeed people meant? http://www.aclperformance.com.au/NissanRB25DET.htm

Only nissan AFAIK have the different size standard bearings. If you look on the bottom of the block there are some numbers stamped where the sump attaches, there will be a series of 6 numberes and a series of 7 numbers. These relate to the big ends and mains. However if you get a set of aftermarket standard bearings, its a case of one size fits all, and just have to check the clearances

yep aftermarket sizes (std, 20, 30 etc) are one size fits all.... i used to keep about 4 or five sets (most rbs and sr's) and trial fit a few from differrent batches to get the best result, but bearings are getting better though.... more importantly so are the machinists
