Default Chinese turbo manufacturers must not think too much of their products...

Taken from the FAQ for one of those companies that supplies eBay turbos - they'd spammed us wondering if we were interested in selling their turbos.

Quote:
Q:Product life?
A:By properly installation, GKM turbo can last for at least 1 year.
Funny thing is, they were just bragging that they had some of the highest quality ChinaChargers, too:

Quote:
Q:Why choose GKM as your turbo provider?
A:GKM is corporation based on high technology. New design in manufacture and new invention in material extremely reduce the production cost and ensure the product quality. So GKM turbo represent the top level quality standard in China mainland area, and price is the lowest.

Boy, I wish my company could get away with bragging on a 1 year lifespan. MTBF on our stuff (broadcast audio consoles) is expected to be more like 10-15 years of 24/7 operation. (excluding mechanical bits like switches and faders)

These guys (the Chinese in general) are learning fast and hard. If they can rip off and build 7 or 8 brands of turbos, which are traditionally considered to be very high-precision machinery, with even a marginal amount of accuracy, then they can figure out how to hold tolerances and ensure consistency. Amen to low-cost performance parts which work well, atleast in the near future.

Ask them for samples and let us know how they perform. I am sure they will send you some freebies for consideration. You have nothing to lose.

or they could grenade in your engine bay... either way it would be good knowledge.

OMG, Have you even seen a chinese turbo? They are seriously not bad for the $$$ spent. I was actually surprised. I will grant you that some are better than others, but so far I've gotten some decent ones.

There is no way that a compressor wheel made of even the cheapest materials known to man will explode at those peripheral velocities and temperatures. A turbine wheel, maybe.....

40 years ago, you could have bought a turbo Corvair that had a 3 year warranty.

if the chinese can build millions of turbodiesel engines for their own consumption, they can handle a few dinky T2 turbos.

it ain't no thang. we can build / copy ALL. have you seen the $9 DVD players?

A few of the Chinese companies selling turbos have tie-ups with major turbo manufacturers like Holset (Cummins) & Garrett. What these companies typically do is build them OE for a while. Then they open another manufacturing unit 10 miles away from the joint venture unit, and start building copies. How bad can these rip-off turbos be? I'm not saying all Chinachargers are good, just that some of them arent that bad.

Heres an interesting (and shady) idea:

Their FAQ states:
Q: Warrant?
A:We provide 6 month warrant starting from the date shown on your selling invoice to your customer.

Soooo if I bought one from you with a sales invoice stating a future date.. I could technically get an extended warranty with the turbo

I don't doubt that they could build a good quality turbo if their main goal was building one that's durable at any cost. However, many of them look like their main goal is trying to make the cheapest turbo that will last long enough for the seller to get good feedback on eBay. Right now it's hard to tell which Chinachargers are which.
