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 :)

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.

      Yes they do. For some maybe. But for those used the most by abusers, ie Skylines, the numbers are known. The stock eyebrow height for R32/3 Skylines is about 365/375mm or thereabouts. The minimum such heights are recorded in adjacent columns in the database.

      Hmmm, interesting. Makes me wonder whether there is bias as well. It's the cheapest fuel, so it is used for all kinds of ill-maintained shitboxes which are bound to have issues regardless. Nicer cars tend to require higher octane rated fuel and can't use it anyway. FWIW, the official NSW E10 facts page is decent.
