chinese t3/t4
 

"Anyone knows what is the maximum pressure for a chinnese T3/T4? That's because I broke one while doing a relative pressure of 1.6bar"

Re: chinese t3/t4
 

ok

Re: chinese t3/t4
 

1.5 bar is the max. you just barely broke it. Better luck next time.

Re: chinese t3/t4
 

should've ran more boost. more flow, less restriction. :8

Re: chinese t3/t4
 

did you run a restrictor????

i got a brand new one $200 shipped

Re: chinese t3/t4
 

oil rectrictor?? yes 1mm

Re: chinese t3/t4
 

i was just asking you if you ran one... im wasnt asking on how small lil bo pete was. im not gay

Re: chinese t3/t4
 

nice

Re: chinese t3/t4
 

I have brand new cdm turbos in stock. I break them prior to shipment so you know what your getting. They are still shiney though. 10 year old chinesse kids make the best polisher in the biz.

UPDATE: After 2 years we finally had a piston failure due to a possible failed injector on cyl#4. We will be rebuilding another stock sleeved vitara motor with some major changes to the setup in hopes of attaining 510+WHP and low 10's with mid-low 140's trapspeeds. STAY TUNED!

Re: chinese t3/t4
 

im still rocking cdm ;D

1.68bar? 24-25psi? unless your taking absolute pressure so 10 psi?

Re: chinese t3/t4
 

that's not cdm internals though

Re: chinese t3/t4
 

im pretty sure they are, I was there in woodburn, OR when james blew it. He didn't actually blow, it just didn't run right. They popped off the head and cyl wall #4 was ----.The rebuilt the motor in the parking lot at night. ran another 10.4 pass the next day.

Re: chinese t3/t4
 

The last Ebay 57 trim I saw had a Garrett bearing housing! The unmistakable "A" was etched into it. I think they can't make their own bearing housings, so go with Garrett. I looked inside and it had Chinese internals and didn't have a compressor housing o-ring lol. It's still sitting in a box unassembled as I'd never run one, but I was curious as to what it had inside.

Re: chinese t3/t4
 

Dude just because a handful come out ok doesnt make them a smart choice.

Re: chinese t3/t4
 

well put.

you can get a good look at a T-bone by sticking your head up a butcher's ass..no wait.

Re: chinese t3/t4
 

Aaaaahhhhhhhhh yes. Classic right thur.

Re: chinese t3/t4
 

a off the shelf ebay 57trim T3/T04E .63a/r will not allow u to make 471whp?? You are talking about this turbo right?? http://cgi.ebay.com/ebaymotors/T3-T4...Q5fAccessories

Because i got one of these and these fuckers start falling off at around 300whp...

Re: chinese t3/t4
 

you left the included stickers and wing off yours tho.

Re: chinese t3/t4
 

hahaha.. wait...

he has hello kitty on his fuel door

Re: chinese t3/t4
 

thats the ultimate jdM

Re: chinese t3/t4
 

You buy the "exact same" turbo from the same supplier, two weeks apart, and it looks the same from the outside but there is a massive difference in the size of the compressor wheel.

I like everything about JFK88 or whatever his screenname is @ SF EXCEPT his standing by china turbos, in all other respects he's intelligent and shows some brass. He's been real lucky with one unit, sure, but literally every last one I see is either already bad before 500 miles or seems like it's good until you reach into the compressor and feel the massive thrust play signaling impending failure. I'm a ------- cheapass who will rig or bypass ---- on his own car far more than most people, but I wouldn't have one of those things on my car. China turbos are a great way to flush all your time effort and money down the shitter when the compressor wheel consumes itself and sprays metal shards into your engine.

Classic.

Re: chinese t3/t4
 

true my ching chong stared hitting the housing i bailed on it i miss it

Re: chinese t3/t4
 

Don't wild guess it once it'S blown, it's more expensive to fix any turbo, chinese or not.
It's possible to make those chinese t3/t4 just as good and reliable as real garrett turbos by replacing the center section, backplate and all the internals including the thrust plate and collar by Genuine garrett components and straighten the shaft, rebalance the rotating assembly properly and that way all their weaknesses are addressed and they are good to go. just don't pick the saddly popular model with the stupid tiny t04e 40 trim compressor wheel on a stage3 .63 hot side!! Make sure you get the REAL t04e 50 or 57 trim (measuring respectively 53.9 & 56.6 mm) and you're good to go. Harder to find, their stg3 T04B's V trim are also full of potential once upgraded with Garrett guts. I have a customer running a pair of them on a mustang 5.0L. They perform amazing and are still lasting after a second season at the track. The two new ebay turbos + the garrett upgrade was still cheaper than getting new, or reman genuine garrett turbos.

I have been running this ebay trash with 0 problems since last december/january. Very very tiny side to side shaft play, nothing abnormal. Never smoked and boost like new all the time. I have never used turbo timer on this. I think that the oil feed line and drain play a big part in this turbo's longetivity.

Re: chinese t3/t4
 

I have run my ching chang turbo too for 2 years 1 year daily driven atleast 30miles a day. This is all with no air filter, a 1/16 homemade oil restrictor on 15psi and i still have barley have any shaft play.This is my 3rd setup with cdm turbos and i will keep rocking them till one explodes on me and destorys my engine, hopefully that never happens :8

Re: chinese t3/t4
 

straight from the mouth of the person who is known for shitty turbos.

the name BLAAST = shittier-than-cdm turbos.

;D

Re: chinese t3/t4
 

I really don't ever come on here, but I just happened to see this and thought I'd comment.

I have never advocated the use of the Ebay turbos, I simply just made the mistake of telling everyone what I was really running. Should've said it was a Garrett 57trim, that would've saved me from the countless IM's and e-mails from people wanting to know which one it is, who I bought it from, etc. I've steered every last one of these away from the Ebay variant.

As for my experience with it, the 1st one I ran for ~1 1/2 yrs and it did OK, but would intermittently smoke and when it did, it was bad. Then it would just go away and not smoke again for a long time - very odd. That one made 442whp @ 29psi and we went 10.8's @ 131-133mph on it. It finally started smoking constantly, and we had another one laying around that was measured and found to be identical, so we put that one on. NO OTHER changes were made to the car or the tune, and it made 471+whp @ 29psi and we went 10.4-10.5 @ 138-139mph on it.

AFR's even stayed the same - the power difference between the two was strictly due to engine/turbocharger efficiency differences related to the thrust bearing damage/wear that we found in the old unit, and the related higher backpressure in the turbine housing as well as changing clearances between the compressor wheel and housing due to excessive shaft movement fore and aft. This is why you'll see lower than normal power output from a bad turbo at the same pressure level in the IM, even if the compressor wheel hasn't contacted the housing yet.

That entire setup is now on another one of our Vitara builds that is daily driven, and the turbo is still going strong. We plan on pushing that build to 29psi as well this year and seeing how it does, since it's a full Z6(better head), and unlike my Y8 which was 75mm and .006-.008 P2W, this Z6 motor is 75.5mm bore running a tight .0025 P2W clearance. I've got a different flavor of Vitara build from the norm going into my car for this year. ;)

We've installed or worked on 100's of cars with various Ebay turbos, and best as I can tell, they run about 40% chance of being bad immediately (within minutes or days).
The other 60%, half will do fine for 3-6months, the other half will run for a good long time, as long as any quality brand turbo. Those are terrible odds.

Re: chinese t3/t4
 

I must disagree slightly, and keep in mind I do so respectfully. The last time I ever communicated with you was on HT, and you were very pro-china turbos. It has been 1.5+ years, though. :-\

Re: chinese t3/t4
 

I got mine from BLAAST and I have it for about a year now running 17psi every day and its like new still.

Re: chinese t3/t4
 

very valid point.

Re: chinese t3/t4
 

I do vaguely remember that, although I can't recall any details. I'm sure that my angle was different back then - I'm guessing I probably said something along the lines of "cheap turbo for a cheap build = good" and that we had seen pretty good things out of them. Do you recall what I said? I really can't recall encouraging anyone to use an Ebay turbo over a Garrett, etc if they could afford the real deal.

Having more time and experience with them since that time, I guess my rating of them has declined overall. It seems to me that they held up better 1-2yrs ago, but it could be all in my head. The 2 that I used personally did extremely well, but you can't even get a real 57trim on Ebay anymore. I was indeed very impressed that they were able to hold up to that kind of shaft speed and make the power.

Re: chinese t3/t4
 

I remember putting my $0.02 in and then not arguing further. Also, there are several different turbo clone factories in china, and the quality of their turbos varies run to run. I'm sure the turbo quality is all over the place, none quite as good as the OE manufacturers.
