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

To finish off the story i have recieved word back from the supplier who has confirmed that the bearings are std bearings 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)

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.

He is sponsored by ACL by looks of pics i have seen of his car lol

added final post to first post as asked i just hope it helps make more people awhere of what they will get when buying the product as i know i would not have bought the product knowing what i know now.

    • You are selling this? I have never bought something from marketplace...i dont know if i trust that enough. And the price is little bit "too" good...

    • It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.
    • By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.
    • There is a guy who said he can weld me piping without having to cut chassis, maybe I do that ? Or do I just go reverse flow but isn’t reverse flow very limited once again?
