Default Car on the road for 2 days and the turbo is ruined :(

Hey everyone,

Pretty gutted right now. I had the car out the second time since last November with my new built motor and GT3071R turbo. Mapping it has gone well but something happened today and I lose all boost pressure.

I had originally assumed I'd blown an intercooler pipe loose until I heard a horrible metallic noise from the turbo. So it seems the turbo is ruined and I'll need a new one?

I understand you can't rebuild a Garrett ball bearing unit. See what you think - I took a video.

If your housings are still good, Garrett has a CHRA exchange program. It will cost you somewhat less than a new turbo.

This is why I always stayed away from Garrett DBB turbos. Some last forever, some don't. And when they do die, it's going to cost a lot.

OP, take the turbo apart and check the housings for scratches and marks. You'll likely get away with just a CHRA replacement, which is not cheap.

How much are you looking at for a new CHRA? It's a .86 gt3071r. What about the Borg efr range? I'd seriously consider getting one if they'd mate up to my FM2 hotside.

CHRA exchange is apparently done in a case-by-case kind of deal, from what I've read. The numbers that get thrown around are anywhere from 400 to 600+ bucks and you will most likely be sent a refurbished CHRA from Garrett, not a new one.

ERF T2 footprint turbos will bolt up to your FM manifold, but not your FM downpipe. You would need to fabricate your own, which will most likely be a supremely tight fit considering the length of the EFR units. I did the measurements when I bought a FM manifold and I was sure I was going to have to cut the rear shelf.

Good luck.

Check for obstructions in your oil feed line. New CHRA from Garrett is ~$466 for the 2871R, so it should be right around there for the 3071R as well.

No it's not. I've had several friends use it and there are no questions asked in my experience.

I asked my ATP rep once about the requirements, and he said it's this simple:
  • The turbo must have never been disassembled or altered in any way
  • It must be a genuine Garrett CHRA

He says they've had people deliver CHRAs in plastic baggies to contain all the parts, and Garrett ships out a new one with no issues.

That's really promising. The turbo has never been dicked around with so should be ok. I've sent off a load of emails to turbo companies here in the uk so I'll see what they come back with. I thought i'd be close to new turbo money, but if it really will be around $466 it'll make it a lot easier to swallow.

Best I can figure, $466 is basically what distributor cost on a new CHRA is. Even if you add retail cost of both housings to that number, you end up several hundred short of retail on a new turbo.

You should contact Owens Developments and see what they can do...if you can contact them. They do fancy bearings for reasonable prices.
