Hi Guys,

I am just passing on a warning to anyone interested in buying tomei bigend bearings, Dont as you will get std nissan bearing wrapped in bubble wrap with a small stricker and at three times the cost of the std bearing. I am not kidding i recently order a set of nismo mains and ask for a quote on tomei or nismo bigends figuring(when quote came through with the tomei units i figured why not same price as nismo) everything else i have bought from tomei had been of good performance grand but the std bearing i removed from this motor had started to fail under the load of 530rwhp plus and the bearing they supplied were stamped nissan with the nissan part number the works even in the nissan vacuum wrapping. So to say i feel like and idiot paying nearly $300 deliveried for std bearing i can buy from the local nissan dealer for $11 a journal is an unstatement i have contacted the supplier of the product to see if i can work something out but i will have to wait and see what happens.

As for using other type bearing i tried sourcing King and had no luck and tried getting acl racing but the local dealers are hopeless and also couldn't source me the bearing either so i when will buy nismo/tomei from japan out of last option.

pete

ps if anyone is chancing std bearings spec 1 from $280 let me know lol hehehe DAMN IT

edit: i was asked to add the final result to the first entry

To finish off the story i have recieved word back from the supplier who has confirmed that the bearings are std bearings which have a coated in the tomei finish(micro finished) then sold as tomei bearing ,so my orginial concern was wrong that there just resold but i was right the the base is a std bearing unit resurfaced. But i have already accessibled the bottom end with nismo big end bearings from x-speed.

so if anyone want some tomei spec 1 bigends for a rb26/25 $200(cost me over $300 to land)

There seems to be alot of the manufactures that use other manufactures products. HKS use Garrett Turbo's - but at least these are modified versions.

I hate to see the same item sold by another company for a higher price. Thats just crap!

I had alot of confidence in Tomei - so far always made a great product. Now have to be a bit careful not to get screwed!

I If I want a Nissan product, I would of bought it from Nissan (unless I knew it was Nissan and it was cheaper buying else where)

Hey Pete,

I thought I told you that? Or was it someone else? They are not quite the standard Nissan NDC bearings. They are treated. (That's what the micro finish buisiness is about).

ACL reace big ends are damn cheap, that's what I am using. Why don't you give them a go? I'm not too keen on their mains though.

hi mick,

like i said in thread i tried to get acl race bearing but the local supplier havent got a clue and the part number list on sau didnt work the mains show up but the bigend number listed on sau didnt. I dont unstand how a simple thing like get engine bearing has come such a pain in the arse. the tomei bearing are still in the std nissan vacuum wrap.

The ACL big ends are 2960's...same as sr20.

Interesting about the bearings being in the nissan wrap. I'm just going off what my supplier in Japan told me...he said they are the same bearings with a special surface finish.

If you get really stuck with the big ends, I can send a set over.

One possibility is that Nissan (or the company they contract) do the extra surface finishing of the Tomeii bearings as a final step in the manufacture of the OEM items. That way they would still end up in the OEM wrapping.

It might not make economic sense for Tomeii to buy, maintain and operate millions of dollars of manufacturing gear for a relatively low volume component.

I probably should have added "seems to be" to that.. their z32 airflow meter is nissan.. their fuel pumps look awefully like the GTR one.. so wouldn't surprise me if something like the bearings are the same. They just stick their badge on it and stick a massive markup on it <_<

somebody might have some more solid info..

The AFM they 'sell' is a nissan one., and they don't try to hide that. It is also prices the same as the genuine nissan part.

The fuel pumps and fprs are the same as nismo ones, and I'm pretty sure a tomei fuel pump is cheaper then an OEM nissan one.

They do share some parts with nismo (cranks as well), but nothing with OEM nissan that I know of (actually, I suspect that their type A valve springs are OEM nissan)

The bearings are definately different. Whether they are any better or not, I don't know.

Clevite SR20 big end bearings are also identical to nissan (NDC) but have a different coating. This could be where the tomei ones are sourced from.

most of the tomei gear is simply rebadged nissan oem..

rofl dude you have to be joking right?

i got a tomei fuel pump and its sure as hell not a stock nissan pump.

as Mik said the afm is a stock nissan item but im pretty sure its just the plugs that are different

In that case - you might want to edit your thread and say you were wrong.

Otherwise people that just read the first few posts get the wrong impression.

So many people on here come and abuse a brand before contacting their supplier and seeing whats up.

i use acl race series bearings now as nismo are the best but bloody dear...

the acls are holding in my rb26 with 900 plus hp so far... no probs...and cheap as...

anyone after some acl race series send me a pm...

This doesn't speak very highly of the Tomei product if a HiOctane sponsored racer wont/doesn't use the Tomei product. Thanks for your honesty Mark.

      RB20DE NEO smallbox clutch.

      By Kapr · Posted

      For once a good news  It needed to be adjusted by that one nut and it is ok  At least something was easy But thank you very much for help. But a small issue is now(gearbox) that when the car is stationary you can hear "clinking" from gearbox so some of the bearing is 100% not that happy... It goes away once you push clutch so it is 100% gearbox. Just if you know...what that bearing could be? It sounding like "spun bearing" but it is louder.

      By GTSBoy · Posted

      Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve.

      I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.

      By GTSBoy · Posted

      No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.

      By Kinkstaah · Posted

      God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
