Hello fellow Mini enthusiasts,

I have some questions regarding repairing an OEM JCW Borg Warner turbo.

I have damaged the outer clamping ring that couples to the Hot side of the turbo, on the centre cartridge.
Also my hot side of the turbine wheel is damaged, from when the two halves separated, and it was rattling around in the casting until it stopped turning.
The cold side is completely fine.
( Wild life collision)

Is it possible to reuse turbo parts (hot side, centre cartridge) from a Cooper S turbo?

I can find them used very easily, but having a hard time finding a legit JCW turbo.
Yes new ones are around, but they fetch a premium price.

Or Does anyone know where to source oem BW turbo parts?

Had anyone felt with G pop ?

Are their parts knock offs?

Thanks in advance.

 

We've tried different rebuilders and not had good results so we only use new turbos in the shop for repair. Worse thing is most the time you don't know if the rebuild is any good until you spend all the time installing it. After we do it the 2nd time for free that is the end of that.

Conrad,

Like Way says, the rebuilds are hit and miss. We've had customers who've had rebuilt turbos from even reputable services last less than 30k miles, and we've had the same results from some of the cheaper rebuilders out there. Like body shops, it's a tough go to find someone who can do quality work and keep it linear, many times it's ups and downs.

We had a local guy doing rebuilds for us and were having good luck, but there were of course a couple in the beginning that were of less quality than we would've liked.

We've since found a local distributor of new Borg Warner chargers and began pushing them moreso than the rebuild just for the reason of the warranty they carry and the quality of a manufacturer vs a rebuilder.

The tolerances, torques, balance, and end play all comes into play when you're rebuilding a turbo and it's not something I'd recommend someone do in their garage, for the time you'll have invested into removing your turbo and reinstalling it I would recommend just going with a new unit that you know is going to work first time and not have any learning curve errors during its assembly.
