So..........

Had to drive the Balt today, since my company vehicle was in for service this morning, and we got issues. I noticed on my way to work this morning it seemed sluggish spooling, even just 3psi with normal driving seemed slow. After leaving the office, I stepped into the throttle a bit just to see what it wanted to do, and it only hit 19psi, the tune is set for 25.

Once I got home I pulled the upper charge pipe coupler at the turbo, and found a nice metal impregnated sludge lining it.


Needless to say I think we have a bearing issue. Not bad, I managed to destroy a new product in less than 1 year with just over 10k on the turbo, of which 6-7k was spent just cruising at 80 on the highway before I got the company vehicle.

Already contacted ZZP, awaiting an answer.

Damn man that sucks! Hopefully you don't encounter any issues with zzp

Tdubbs

I think I got it up now.


I hope not. I'm easy going and don't attack people when **** goes wrong, and it usually leads to better service lol

Ew, yeah, that looks like some high-speed grinding going on. Good luck.

I wonder if you are the first to roast one

Tdubbs

I know I'm not the first with a 6758 that blew, but this is the first for the z54 I've seen. At least I'm under their 2 year warranty time wise, just have to see what they say.

There is someone on Facebook that also had issues with his impeller hitting the housing.

Tdubbs

Welp, got my answer, no warranty. Ryan emailed Matt since he handles them and I was told 25psi is too much for that turbo, they usually run 22-23 max.

So now the dilema, **** a few hundo to rebuild it, and then some to get the same power I was just at, or throw it in the trash and buy a WR-3. Decisions decisions........

does it specifically say on their site that exceeding 23psi voids the warranty? seems kinda silly...

"Since the release of our ZFR bolt on turbo for the Ecotec platform, it has been a very popular product. Our ZFR turbos offer an amazing combination of high horsepower potential with minimal turbo lag. However, the dual ball bearing system and titanium-aluminum alloy exhaust wheels add a considerable amount to the price of these turbos. For the last two years, we have been in development of a more affordable version of our ZFR 6758 turbo. So far the results have been very impressive. Our new journal bearing Z54 turbo has been tested to extreme power levels and it performs even better than most were expecting. With a full list of ZZP parts on our ’08 Cobalt SS, we achieved 480 wheel horsepower on E85.

Our Z54 turbo is designed to bolt in place of the factory K04 turbo on the LNF motor. It allows you to reuse your existing intake and exhaust parts without any adapters. While boost will still be controlled by your ECM, you will still need to have your tune set up for this turbo. The wastegate duty cycle chart is the main area that needs to be modified. Since this turbo is fully manufactured and marketed as a ZZP product, it also carries our standard 2 year warranty. "


says they made over 480whp, also says 23psi voids warranty.... right...

Tdubbs

It does not, all it says is since it's branded as a ZZP product it gets a two year warranty.

That's bs they should honor the warranty

Tdubbs

My point exactly. I mean don't get me wrong I didn't expect it to live forever, but if running 25psi was considered too much there should have been a disclaimer on the page to avoid said boost levels. I sent an email back asking why info like that wasn't on the page if that was the case. I even said I wasn't knocking them, just wanted to know. But I haven't heard back, and probably won't tonight. I'll keep this updated as I go along and decide/see what to do.

It's one thing if you push it 25 and it's stated to not run over 23. But if they don't specify that, then they should back the warranty.

This is when you start attacking people.

anyone know whos center section these turbos are? ive been trying to figure it out, the compressor and turbine wheels are the exact same sizes as the efr 6758, but i cant seem to find anyone who makes a journal bearing turbo with those specs.

Tdubbs

UPDATE:

Still communicating with ZZP, so it's not a definitive no yet.


I'm under the impression they are assembling the center sections in house, as I don't know anyone else who has a non ball bearing EFR series turbo available.

KMO43

Wow this is surprising. How can you say this turbo makes 480hp as a selling feature then not warranty it when people try to do so?

KMO43

Come to think of it how can a 54mm turbo not supply a 2L engine with 25psi when our stock k04 can run 24 to 25 for years? The shaft speed on the Z54 would be way lower than the K04 but it can't last at that boost?

oh, come on.

This is COMPLETE horse ****.

There is no way they can claim that it supports 480hp, and then suggest that when something goes sideways that they are not meant for more than "22-23psi" - I'd wager the 480hp pull was with more than 23psi.

I have been contemplating one of these, but I guess I have my answer right here...

Tell them you want a zfr replacement, not their shitty z54.
