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

      R33 GTR running -9 with no tune

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.

      Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.

      Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it

      Coolant leak?

      By Duncan · Posted

      Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground

      I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.
