Hi mates I want to get some bearings for my turbo. The size I need is 26x10x8. Does anyone know where I can get them? My local bearing shop only had one the said was rated to 12000 rpm but when I googled it it was actually 36000 rpm in oil.

What speed do they need to be good for?

When you get shaft play is it from the bearings?

Bearings are the least of your dramas. How are you re balancing your turbo? 1/4 of a gram gets VERY heavy when you spin it quickly! What turbo is it for? Most modern garretts are non rebuildable. Most are only available as a core (bearing, housings turbines etc, pre build, pre balanced)

If you need bush bearings, then I can get them easily through a local turbo supplier.

Shaft play which way? in out or up down?

You can't. Garrett make it very hard and or expensive to get replacements. That's one of the reasons the GCG rebuilds are so expensive. Try Hypergear - he will know if they can be got.

I wouldn't try rebuild it. Balancing is the main issue. As for the speed. 150k to 200k more than that is over spinning your turbo. Danger will Robinson danger. Lol

During the VNT CBB development the shaft speed of the SS2 Alpha have maxed out the gauge of 180,000RPMs around 5000RPMs, so by the end of the run of 7200RPMs it would be over 200,000RPMs.

The 12,000RPMs bearings don't work, they could be easily obtained, those were the first ones I've tried and Very nosy.

Apart from balancing, and shaft speed there are many other critical areas to be considered. It took me close to a year to workout all aspects and having it working reliably.

Yeah I've only ever rebuilt turbos for large diesel engines which only rev to about 2100rpm, and they were pretty heavy duty bush bearing turbos. Fair bit of screwing around getting everything right on the shaft then balancing the thing. This is why I gave my original comment. If he can't source bearings, I dont know if I could trust the final build of the turbo

Talk to Stao ^ ^ ^ ^ ^ ^ ^ ^

He definently knows his stuff, plenty of happy customers on here, myself included

      Possible swap on R34 RB20DE NEO?

      By Kapr · Posted

      Hi. A little bit of an update. It maybe(hope not) looks like i would need a new tranny(it would be "maybe" a cheaper or better option anyway) So i need some info. I know i need a different propshaft(i can make custom one) LSD is not a problem cuz the engine will be still(for now) N/A RB20. So if i buy RB25DET NEO tranny...is there something else i need? I read something about push/pull type but i do not know if i need to "change" something or i can just plug n play onto my engine a go? Thanks for the advice

      Turn signal wiring question

      By OakvilleGTR · Posted

      Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance

      Mistakes were made, my R34 Story

      My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..

      Lower A arm Skyline v35

      The bushing has failed, not all that uncommon for a car of this age.  Any mechanic should be able to push in a new bushing for you, or you can probably buy the entire lower control arm, complete with bushes.

      Could you not use "thermal" spacers to give the clearance, like the ones I used between the blower and head? That raised the manifold height by around 10-15mm Albeit the ones I used were for cathedral ports, but I assume they have similar for rectangular ports????
