do you mean bearings or rods and pistons

[Chris Wilson]

Yes, just like Nissan, grades are on crank and block.

 

I think http://www.coordsport.com will have the ARP bolts.

The bearings in particular. There is so little difference between OEM and aftermarket that I would personally go aftermarket with a known decent brand. Gives headroom for any future mods too. Changing the bearings and the rod bolts are taking out the well known weak areas of the stock block

 

Piston rings would be next on the list for me.

With the OE bearings, if you have access to proper measuring gear, you can get the clearances to your liking or Toyota' recommendations, with aftermarket most are one size fits all. With a good used crank a quick polish and sizing means you can spec a slightly O/size bearing from Toyota to get clearances tighter than an aftermarket bearing may be able to achieve. There's a lot to be said to sticking OE with sized bearings if you want clearances spot on.

 

The best piston rings in the world are considered those from Japan, most US ones are dire, in sizing, tolerances and sometimes material. They certainly need hand gapping, and that's something which is definitely a bit of an art form without a ring grinder.

I was looking into this a couple of weeks ago. The PE bearings are 6 sizes and are said to be the best available.

 

I would just go with stock rings, but I would still replace them if I was in there

again thanks chris i'll give paul a shout

 

same as acl on rb26 made with a one size to fit all which is why you see so many rb26 with bearing failure after rebuilds

 

i'll stick with the oem stuff i think

[Chris Wilson]

If it were my own engine I would. My RB26DETT is on stock bearings, as is my Toyota 4A-GE turbo engine.
