I know that not everyone wants to get their hands dirty here but maybe someone has done this?

The turbos on my RS6 engine have a bit of play... not enough for me to throw them away (they work!) but enough for me to consider rebuilding them...

So after a quick Google... I've found these...

Anyone here played with replacing the cores?

If not, who does a good rebuild service that is reliable?

I have. Well I'm currently rebuilding a TD05HR to a 20g spec. It's not that hard. You just gotta make sure you get them balanced which is only around £50 so it's silly not too. Just check for excessive wear on parts and make sure you put your oil seals on correctly.

I do plan to build hybrid k04's for my car in the future.

Excellent thanks for the reply.

Did you buy the same cores?

I used to the oem CHRA as it was fine to use. Plus you have to be careful as there's a lot of cheap replicas around. So you're better off sticking with oem and updating bearings etc. The hardest part is if you wanna put on bigger wheels as it'll mean machine the turbine/compressor housing.

Ok thanks. Do you have a link to the supplier please?

That company you linked above actually sells genuine Borg warner rebuild kits. I've not used them yet as I haven't had the chance to build a k03/04 yet. Only done the TD04/05 which are made by MHI and used mainly on Japanese cars.

Oh and I've seen the previous post on the gearbox rebuild. A turbo rebuild should be a walk in the park for you!

Perfect thanks. I've had Turbos apart before inc building hybrids but never RS6 versions. It's always good to research first

Yeah I've always looked at RS6 parts almost at a 'mythical' state because of the car, but as far as I'm aware they're just k04 turbos. It's the inlets that link them to the car. But if you go hybrid you'll have to lose them and machine new inlets.

Danny at turbo rebuild is a stand up guy and knows his stuff . He rebuilt and machined my turbos last year new cores bigger compressors , 360 bearing housing machined to match ect ECT ECT.

Can you remember how much mate? Just I'm going to pull my engine at the next of the year and might get mine rebuilt while I'm at it thanks

I can't remember exactly, but I think It was around the 1k mark for both of them . That was new cores , machine work , oversized wheels 360 bearings ect.

Deep breath...

Ok here goes nothing (well, £318.22 actually!)... I've gone for the Turbo Rebuild Ltd cartridges and will swap everything over myself.

I pulled the gearbox off last night so one of the turbos is already off. i have one seized stud that I really don't want to have to drill out but I think I need oxy/ac to get it undone.

I ended up drilling and heli-coiling mine.
Use lots of nickel grease when you put back together!

Actually, that's not quite true. I did manage to drill them out successfully and save all the threads - but truth is they were a little sloppier than I was happy with, so I then re-did and heli-coiled them.
