Ok Out of interest. who on here has actually used a Chinese turbo on their car or another car. what was your experience?
I know a lot of people on here are against them but is it based on real experience with them or just typical internet forum speculation?
This chaps pleased with his:
A friend had a huge Chinese turbo on his 200SX. Besides ridiculous levels of lag it lasted a few thousand miles before the compressor wheel acted
like a fragmentation grenade. Can't rule out something passed through it though.

Never used one, butI would expect that most are very good, but depending on the engine, it could be an expensive mistake if yours wasnt, although
obviously anything can fail.

They seem to have a reputation for failing really quickly and taking half the engine with them, but when you try and trace the story back they tend to
get very vague.
Out of the few that can be traced, they end up very similar to that youtube video. It's 'oh, it has actually lasted. That's a
surprise'...
My view is, if they cost a third of the price of a name brand, but last a third of the time, then you've broken even.
Depends on the nature of the company.. I work for a certain manufacturer, and we see copies of our turbos all the time.. They look the part, and have
the detail (even down to the brand ID of the genuine foundries), but not necessarily the Engineering behind the product.
Point in note, when containment tested (burst test), the turbine housing was proven to be made of the ferrous equivalent of toffee!
Not pretty when your turbine blades are whizzing round at 120k RPM...
Cant comment on Chinese OEM though...
How well would a "quality" housing stand up to a turbine blade failure? Genuinely interested.

They contain! It's one of the fundamental safety checks conducted during the product design / approval process. Key criteria is when a wheel
failur is induced that the housing holds (compressor or turbine end). Its qchieved through controlling the wall thickness and the ductility of the
material.
If one was to go, it ensures you don't have turbine blades coming thru your bonnet (or up your backside if the engine is below you - think
HGV!)
Seriously fun test to watch
I've seen more than one turbo-based-turbine shatter taking the compressor housings with it. Clearly non-standard use of course.
China = crap
That's really quite unfair to be honest - we outsourced a bunch of CNC work to china and they were cheaper, higher tolerance and faster than any of the UK based manufacturers we could find, including shipping time.
EVERTHING i put on my MGB that was made in China is in the bin. Some critical parts like the servo, leaf springs, the list goes on.
They were all badly made or fell apart. i fitted a waterpump and the pulley bolts hit the casting !!
Maybe you mean cheap then?

''I boycott Chinese products (and some others) wherever I can.''
Me too though it's often quite difficult to find an alternative.
Beware of the rice eaters for they shall inherit the Earth..
I dont mind chinese products in some cases, but i am sick of seeing some of the junk they make and ship. Like crap toys and ornaments, nasty cheap junk which i object to both for the waste of resources, and the fact that the trade deficit is going to cause us some serious trouble in future.
back to the topic i wouldnt touch one with a bargepole and i dont know anyone who has got more than a few 1000 miles from one and even less once you start going above 1 bar of boost
Not on topic really, but the VW plant here in Uitenhage South Africa. has just been awarded a large contract to manufacture engines for export to
China! Makes me feel quite proud.

Ever asked yourself why it's cheaper / faster? The fact of the matter is that the Chinese can undercut everyone because they pay their workers a pittance to work ridiculous hours in terrible conditions whilst causing incredible levels of pollution without any systems of control.
I'm delighted you know of 2 companies in China that treat their workers well. Hopefully the hundreds of thousands of others that treat theirs
like sh*t will follow suit!
As for generalising... there are 1.3 billion people in the country... of course I have to generalise!
You also make mention that the cost of 'living' in China is cheap. I'd perhaps change the word 'living' to
'surviving'. They are very different!
Don't get me wrong. I have little sympathy for them. I'm a great believer that you reap what you sow and that the entire human race (in
general terms!) will get what's coming to it. It's just a shame that the whole planet has to suffer as a consequence of our over-breeding
and locust-like behaviour.
All together now... I'M H-A-P-P-Y!!!
I just doubt the logic of buying a cheap part (regardless of where it is made) that could if it failed wreck your engine and end up costing you much more in the future than your original saving

I've no doubt whatsoever that the cost of living there is cheap... for someone coming from the west!
But that's not really relevant. In this instance, the only thing that matters is the cost of living (perfectly well) for the Chinese citizen.
Let's face it. A 66% pay-cut in your UK wage would not put you anywhere near the pittance paid to the average factory worker in China (about 60p
per hour).
