hey guys

i was at a shop the other day were my mates engine was getting built and my friend asked if he has had any experience with ebay turbos and he said he has and cant fault them :cool: he said garret and a few other turbos are made in china aswell?? i didnt really beleive him but just putting it out there

i havent searched to see if this had been brought up before sorry if it has..

Last time I checked, china aren't on the cutting edge of turbo charger technology.

Case in point:

http://cgi.ebay.com.au/DUAL-Supercharger-T...=item3cacdb3909

Lol you gotta give it to em though, they know people will pay for absolute shit if they make it sound awesome. "DUAL SUPERCHARGER TURBO FUEL SAVER FAN!!!!!!!!!!!!!!!!". Come on... Supercharger, turbo and fuel saver all for 17 bucks!? That's gotta be awesome and work exactly how they say it does! Group buy on the intake restriction?

I run an ebay turbo on my rb30.

And I don't get the anti-china thing? If those guys can accurately put together the thousands of precision bits you are typing on, they they can build a big cast fan.

Yes my turbo is a bit laggier and not as efficent as some, but it delivered my goals for a street motor at a good price. And it might not last as long, but I can replace it 5 times before its worth buying a garrett.

BTW on custom race turbs from Garrett are built in america. Everything else is built in a third world factory just like your nikes

it's important to clarify what you mean, do you mean a no brander ebay turbo such as MONSTA, KKR, T3/T4

i call these "ebay" brands as they are typically junk, cheap spec, poor match, don't mate up and have no real solid brand

yes they may work as duncan said and may do the job, but usually its an inferior product and there are comprimises

there is nothing wrong with turbochargers made in china, garrett and hks one's would be made in china no doubt

its an issue where a cheap product or brand is made in china and there is poor quality control, r&d and a poor basic product

ie a HKS turbo made in china would be fine vs a MONSTA T70 turbo made in china

Yes my turbo is a bit laggier and not as efficent as some, but it delivered my goals for a street motor at a good price. And it might not last as long, but I can replace it 5 times before its worth buying a garrett.

True, I have an Monsta eBay front mount because all it is essentially is is a massive heat sink not much could go wrong other than it being less flowing or effective than a hybrid or ARC.

But for something that spins at a million RPM I personally would want to make sure it's of high quality as more of a safety precaution than anything. I haven't destroyed any turbo's yet but I imagine it could get pretty nasty...

And as Paul said, it's more about the product as opposed to where it was assembled.

The most important computer parts that we're typing away on right now are (and have been for at least a decade) actually created in America with the less critical stuff from mainland China. With the exclusion of Taiwan, but I think that was more of a western push originally.

Not having a go, just while we are sorta on the topic, I thought turbos spin at like ~80,000-150,000? or am I way off?

And I don't get the anti-china thing? If those guys can accurately put together the thousands of precision bits you are typing on, they they can build a big cast fan.

Beaten by paulr33, but Chinese manufacturing is all about quality control. If you have the parent company standing over the manufacturing plant watching every move and making sure the job is done right, it's fine. If there is no control then you get a shit product, but you get it cheap.

Considering you get a motherboard that works for 3 days and then dies, you warranty it and continue on. When it comes to a turbo spinning at crazy speeds and possibly sending a compressor wheel through your engine the variability you get with Chinese products makes me steer well clear. You are putting a lot of trust in someone doing good QA, because the Chinese culture is to do it cheap. Japanese culture (by comparison) is to do it well, and that's expensive. Look at the premium brands for car parts - HKS. Trust. Apexi.

On the other hand, Chinese radiator and bellmouth dump pipe? no problem. Got both on my car and they work OK.

i buy quite a lot of boutique turbos off ebay that are made in taiwan, but they have a proven track record and are quite uncommon.

Taiwan is generally a higher quality product. We deal with electronics suppliers from both countries and my general impression is that the Taiwanese are more skilled.

Branded turbocharger or any product would follow the following principles:

innovation, evaluation, production, quality analyze, distribution, pricing, after sales, profit taken

Some Low cost products on ebay consists only:

production, distribution, pricing, profit taken.

In general branded products has better performance, reliability, and after sales support.

i always thought that they were junk, but in saying that when i was down for stadium drift in the goldy this guy that was talking to us has a 180sx and apon showing us under the bonnet was like a chinese 2 dollor shops window everything was!!!

i was in disbelive that this t3/t4 turbo on a SS highmount manifold and 38mm gate not only made 247RWKW but had for nearly 2 years so the guy said.... and it looks like it had been there for a while to and judging by the car had seen an arse flogging!

i would never use a no brand chinese turbo, manifold or gate on my car but was amazed that this car seemed to use it all and work well??

althought he said it didnt come onto boost till about 5k

    • Well, that's kinda the point. The calipers might interfere with the inside of the barrels 16" rims are only about 14" inside the barrels, which is ~350mm, and 334mm rotors only leave about 8mm outboard for the caliper before you get to 350, And.... that;s not gunna be enough. If the rims have a larger ID than that, you might sneak it in. I'd be putting a measuring stick inside the wheel and eyeballing the extra required for the caliper outboard of the rotor before committing to bolting it all on.
    • OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup
    • I forgot about my shiny new plates!
    • Well, apparently they do fit, however this wont be a problem if not because the car will be stationary while i do the suspension work. I was just going to use the 16's to roll the old girl around if I needed to. I just need to get the E90 back on the road first. Yes! I'm a believer! 🙌 So, I contacted them because the site kinda sucks and I was really confused about what I'd need. They put together a package for me and because I was spraying all the seat surfaces and not doing spot fixes I decided not to send them a headrest to colour match, I just used their colour on file (and it was spot on).  I got some heavy duty cleaner, 1L of colour, a small bottle of dye hardener and a small bottle of the dye top coat. I also got a spray gun as I needed a larger nozzle than the gun I had and it was only $40 extra. From memory the total was ~$450 ish. Its not cheap but the result is awesome. They did add repair bits and pieces to the quote originally and the cost came down significantly when I said I didn't need any repair products. I did it over a weekend. The only issues I had were my own; I forgot to mix the hardener into the dye two coats but I had enough dye for 2 more coats with the hardener. I also just used up all the dye because why not and i rushed the last coat which gave me some runs. Thankfully the runs are under the headrests. The gun pattern wasn't great, very round and would have been better if it was a line. It made it a little tricky to get consistent coverage and I think having done the extra coats probably helped conceal any coverage issues. I contacted them again a few months later so I could get our X5 done (who the f**k thought white leather was a good idea for a family car?!) and they said they had some training to do in Sydney and I could get a reduced rate on the leather fix in the X5 if I let them demo their product on our car. So I agreed. When I took Bec in the E39 to pick it up, I showed them the job I'd done in my car and they were all (students included) really impressed. Note that they said the runs I created could be fixed easily at the time with a brush or an air compressor gun. So, now with the two cars done I can absolutely recommend Colourlock.  I'll take pics of both interiors and create a new thread.
    • Power is fed to the ECU when the ignition switch is switched to IGN, at terminal 58. That same wire also connects to the ECCS relay to provide both the coil power and the contact side. When the ECU sees power at 58 it switches 16 to earth, which pulls the ECCS relay on, which feeds main power into the ECU and also to a bunch of other things. None of this is directly involved in the fuel pump - it just has to happen first. The ECU will pull terminal 18 to earth when it wants the fuel pump to run. This allows the fuel pump relay to pull in, which switches power on into the rest of the fuel pump control equipment. The fuel pump control regulator is controlled from terminal 104 on the ECU and is switched high or low depending on whether the ECU thinks the pump needs to run high or low. (I don't know which way around that is, and it really doesn't matter right now). The fuel pump control reg is really just a resistor that controls how the power through the pump goes to earth. Either straight to earth, or via the resistor. This part doesn't matter much to us today. The power to the fuel pump relay comes from one of the switched wires from the IGN switch and fusebox that is not shown off to the left of this page. That power runs the fuel pump relay coil and a number of other engine peripherals. Those peripherals don't really matter. All that matters is that there should be power available at the relay when the key is in the right position. At least - I think it's switched. If it's not switched, then power will be there all the time. Either way, if you don't have power there when you need it (ie, key on) then it won't work. The input-output switching side of the relay gains its power from a line similar (but not the same as) the one that feeds the ECU. SO I presume that is switched. Again, if there is not power there when you need it, then you have to look upstream. And... the upshot of all that? There is no "ground" at the fuel pump relay. Where you say: and say that pin 1 Black/Pink is ground, that is not true. The ECU trigger is AF73, is black/pink, and is the "ground". When the ECU says it is. The Blue/White wire is the "constant" 12V to power the relay's coil. And when I say "constant", I mean it may well only be on when the key is on. As I said above. So, when the ECU says not to be running the pump (which is any time after about 3s of switching on, with no crank signal or engine speed yet), then you should see 12V at both 1 and 2. Because the 12V will be all the way up to the ECU terminal 18, waiting to be switched to ground. When the ECU switches the fuel pump on, then AF73 should go to ~0V, having been switched to ground and the voltage drop now occurring over the relay coil. 3 & 5 are easy. 5 is the other "constant" 12V, that may or may not be constant but will very much want to be there when the key is on. Same as above. 3 goes to the pump. There should never be 12V visible at 3 unless the relay is pulled in. As to where the immobiliser might have been spliced into all this.... It will either have to be on wire AF70 or AF71, whichever is most accessible near the alarm. Given that all those wires run from the engine bay fusebox or the ECU, via the driver's area to the rear of the car, it could really be either. AF70 will be the same colour from the appropriate fuse all the way to the pump. If it has been cut and is dangling, you should be able to see that  in that area somewhere. Same with AF71.   You really should be able to force the pump to run. Just jump 12V onto AF72 and it should go. That will prove that the pump itself is willing to go along with you when you sort out the upstream. You really should be able to force the fuel pump relay on. Just short AF73 to earth when the key is on. If the pump runs, then the relay is fine, and all the power up to both inputs on the relay is fine. If it doesn't run (and given that you checked the relay itself actually works) then one or both of AF70 and AF71 are not bringing power to the game.
