Chinabay Turbo

[johnloves850's]

HY series turbos are smaller and spool quicker, you can pick up an HY35 for a couple hundred dollars, and would probably be your best option for power/usability

Didn't I just say this 6 posts ago? :lol:

Spool with Holsets are related to their hotside housings. Almost all the used ones come off of diesels and have huge hotside housings which takes a lot of air volume to spool (hence why they're on 7.3L diesels). You need to find a smaller housing most of the time, the 9cm^2 housings are a good match for a decently sized engine. And then you'll have to source a different wastegate as well since most of the diesel application Holsets came with 20psi wastegates.

Even with switching all this stuff to make a usable turbo for our engines it's still a late spooler compared to other similar sized turbos. One of the big reasons why I switched away from wanting an HX35/HX40. HY35's are okay, but I have a buddy with a talon running one and I wasn't all that impressed with it. Seems to flow a lot less than a HX35 and it's not like it has super quick spool to balance it out a bit. Just my .02.

I hate spewing out turbo info. When I was in the market for a turbo I spent hours going over compressor maps and reading up and learning about stuff. Put some effort into it people!

well let me add my .02 to it. it's a repeat though. get the china turbo, most of them are built there anyway. if it makes you feel better gut it, rebuild it. done. a previous post mentioned buy a more expensive turbo. but remember they don't necessarily last longer. the Holset turbo's are good also. everyone in Sweden runs them they make stupid power. So do you research, make a choice. at least with the china turbo when something happens it wont cost you a left testical to replace. Have fun :D

now if I can get my ebay turbo to last 1/5th as long Ill be happy

Because thats all the longer your engine will last with all the money and knowledge you are dedicating to tuning :D

So what is it you are trying to say. only expensive parts are good parts. thats funny, and so not true. I have known many what i would call garage budget builds that last. but on the other hand i have known and or read about people using expensive stuff it craping out repeatedly. this happened to several people in Volvospeed. wasn't there someone here going through precision turbos like candy. just picture the money he went through. remember money doesn't equal quality. like i said do your research and make a choice. Oh and by the way a lot of folks are using the china turbos under cover : ) just wont admit it.

Or, just pay attention whenever this topic comes up so you can see me post that over 3 years ago I tried this on an 850 and it doesn't fit due to their turbine housing design. Unless they've changed the turbine housing casting, you're out of luck.

I feel like I have to re-explain this every time this topic comes up because nobody else here has tried it and nobody remembers me saying it 1000 times.

The turbine housing pushes the center cartridge lower due the design of its casting (compared to say, a standard Garrett T3 or a GT series turbine housing). This makes the compressor housing hit the transmission mount on an 850, and it also makes the drain path a little crappier where it was already pretty crappy for a journal bearing T3 series turbo in the first place.

Get it, try it, but at least I warned you (damn I'm feeling generous today ).

Nope just suggesting that tuning is another part of the equation and I haven't seen the OP demonstrate a lot of ability in doing any of his own research. I don't have an issue with inexpensive parts or garage builds, people pulling them off help's to broaden everyone's knowledge of whats possible.

Are you reffering to an Hy35?

This is painfully true. Happens a lot on my local forum here in London. People have listed that they're using Garrett T3/T4's but people called them out at meets that it's a chinabay turbo.

I believe the above^ poster is speaking of the chinabay turbo housing design. Also happens with the larger GT series turbos.

I'm a little confused myself...

I cant find any of the links now, but was reading up on chinabay turbos and components while shopping for an upgrade for my stock TD04. Its not just the manufacturing tolerances and soft parts like seals and bearings, but also the wheels and shaft that are of inferior quality. First of all the turbine wheels and shaft are often made of some sort of steel rather than inconel type alloys as they are with higher quality turbos. The drawbacks of this should be obvious. The compressor wheels are cast using inferior low pressure casting methods and lower grades of aluminum. This translates into higher chances of fracture and faster fracture propagation. Another problem with the compressor wheels is they are so far out of balance that the companies drill out a hole in the metal and fill it with a lead plug to get the balance right. When you consider the properties of lead, the heat (even on the compressor side) and the forces acting on the wheel at high rpm you can see how this plug can deform and possibly eject material into the intake stream. Despite the fact that the intercooler will catch this stuff, any change in mass can offset the balance and I still dont like the idea of my turbo spewing material of any sort.

Now I'm gonna rant about people who shop price rather than quality and drive up the cost of high quality products. Its happening with just about every product offered in the consumer market, people buy lots of cheap stuff instead of buying less of higher quality. It rewards manufacturers who cut costs and quality and forces those who still offer high quality products to offer them at higher prices. Even if you somehow get away with it (sell the car before the part fails etc...), someone will end up paying for it eventually. As a whole, the process of production and consuption becomes less efficient and we get less utility from what we put in. Realize I'm not targeting people who buy entry level products with fewer features, but people who sacrifice quality to get something that cant possibly be built well for the price they paid for it. This obviously applies most to products whos service life or functionality is directly related to its build quality, for example turbos! Moral of the story, dont buy a china turbo. If you are on that tight of a budget buy used high quality parts.

Chinabay

Sorry, read all the chinabay talk and kind of skipped over the Holset parts. Holset's a good choice... No personal experience there on an 850 ;)

Exactly, and explained with so much more tact...

Here is some info.
