If the crank touches the bearings while running the Oil system isn't doing it's job, "might" make a difference on a Cold start but most modern Oils are quite sticky so "should" provide a film even if let sit for months at a time, first start is the other time it might be useful but that's what assembly lube is for.

I just recieved my Beck/Arnley bearing set from rockauto. com. I got all excited when i opened the thrust washers and they were NDC but the Mains and rods are reboxed ACL bearings. I just wanted to see what kind of bearings were in Beck/Arnley Boxes. I took one for the team just so we can all have more info on the bearings for the 7m. Im still gonna use them for my daily mid 350 rwhp build. Here is a pic of them.

NDC/Clevite are the only bearings proven to hold up in a 7m for over 1k HP
Untrue. I run OEM bearings. ;) Car runs like a champ too. I've always run OEM Toyota bearings, and the engine has been apart several times during which the bearings were always inspected.

My engine is over 1000. ;) (no burn here) Admittedly, only for brief spurts - 9 seconds or 10 seconds at a time on a track, or a bit more on a dyno - you really can't consistently use that much power without getting tossed in jail. So, this isn't proof positive that the OEM bearings will take the load for any significant length of time, however it is a good indicator, and every mile of torture I put the engine through makes them shine a little bit more. Furthermore, while I'm working on proving the OEM units are ok for this level of power, I've not seen anyone put them to the test and have them *fail* at any power level. I'd be happy to see some evidence that they won't hold up - and that the failure was due to the bearing material, not lubrication.

I haven't posted anything about the auto swap, manual swap again or last dyno either. ;)

I will retract my statement when you post a dyno sheet of over 1000 WHP. :)

Titan said that their bearings are ACLs, but they are coated so that they are more comparable to the ACL Race bearings. I called them and that's what they said.

ACL (Real Street Performance)
Enginetech (Rockauto)
ITM (Rockauto)
Sealedpower (Rockauto)
Toyota
Clevite Mahle (limited stock, Jegs)

Anyone have part numbers for the NDC bearings? Seems Clevite are made by Taiho now.
I just tried to get it for you by Googl'ing

"NDC Engine Bearing for Japanese Vehicles Catalogue"

You have to sign up for a "scribd" account to get the file... and I didn't care to do so.


Amazon searches for "ndc rod bearings" with a filter for the car, changes the brand name in the results... so that was no help.

I googled as well and only found rod bearings on ebay in AUS. Was hoping one of the guys over there would post them up to make googling easier. lol

I get you. It's a logical place to ask and someone will probably reply. On the other hand, there's a catalog with the numbers in it at the link provided :)

Are Taiho good? It seemed like people on the Facebook groups were under that impression.

I haven't taken my block to the machine shop yet, so I'm not sure on what sizes I'll need yet.

I am not sure. I have a crank that "should" just need polished at std. At least when I stored it away over a decade ago it was. Im expecting to need 0.25mm undersized though just in case. I will not order them until the crank has been checked though. I want to have the bearings in hand so I can tell the machine shop what the ID is for each bearing and what clearance I want to run etc...
