Some of you may remember my cringe worthy cxracing "review" post from 2012. I thought I would pop in for an update, but that thread is locked, and this one will probably get locked too. Anyways, it's been about 5 years since I started using the turbo (cxracing 57 trim china charger). My car has a simple stock b20 with cheap China parts, making somewhere around 250hp. I haven't really changed my setup at all in the past few years since I've mostly been focusing on my education. I don't have a lot of time or resources to build cars right now. I have been using my car as a daily commuter.

I haven't had any major issues with the car at all, other than suspension components and miscellaneous gaskets needing replaced. The turbo and engine are still going strong. The car still pulls incredibly hard (for me anyways). I haven't noticed any oil consumption or smoking. I don't have to add oil between oil changes, and I usually go 5k between servicing. I think I even went 7k once. I use rotella 5w40, even in the winter.

The last time I inspected the turbo was in December 2016. I took the exhaust manifold off and replaced some gaskets. The turbo didn't seem to have any more shaft play than when it was brand new, and there was no in and out shaft play. I don't drive as much as the average person, so over 5 years I've driven the car just under 40k miles. The odometer will be climbing fast now though because I have a longer commute.

All in all it's been great to me. I beat on the car all the time, and it just doesn't care.

Just thought I'd update for the people who were genuinely curious, if anyone even remembers.

Cool. How much boost is that?

 

Thanks for taking the time to update us, seems these cx racing kits and all China eBay turbo stuff is much better then it used to be..

i have a friend with a cx racing turbo kit on his fox body mustang and he has been happy.

 

about 10psi now.

 

I think the only reason why the last one got locked was only because it went into a different direction as to what criteria you need in order to categorize what you wrote as a "review". You then proceeded to believe that the criteria described was "petty", that people like myself were automatically throwing "shade" in your direction because the turbocharger unit at issue was not one of the major manufacturers. It went downhill from there with endless tirades and it just got closed.

I don't think this one will be, as long as everyone remains civil and reasonable in their position.

In which we now come to my statement. And I'll reiterate now as I did then : these series of manufactures turbochargers and whether they actually functioned at all wasn't the question. Nor was it just a time duration of their utility (6.months, 5 years, 10 years, etc..). I know that this series has stepped their processes up a bit, I stipulated to that point.

the question was the thrust loads that this series could handle. 10psi on this setup is very much on the conservative side of its utility, so there's no surprise that it's still alive with proper maintenance. ( I'm glad you're at least documenting it for the masses that are curious). With that said, I still maintain, (as I've taken a few CX Racing turbos apart since our last encounter ) that higher thrust loads from much higher boost pressure levels hurt these turbos in the long term. You've held 10psi for 5 years. Awesome. Many of us still have yet to see 20-40 psi of load on the same size unit you have. When that becomes more common, I'll be more willing to subscribe to your premise.

I do thank you for returning with your update. I'll do my best to help keep it civil for you so more feedback and input can be gained.

I think that everyone has matured at this point, or simply moved onto some other controversial topic.

 

They've used a couple thousand unknowing participants for their R&D

When I did my first turbo build back in 2004, I bought (at the time) procomp head studs and some chinese BOV and tial 38mm knock-off wastegate.

The head studs were supposed to be torqued to 65ft-lbs and ALL of them broke around 60ft-lbs. Ended up buying ARPs which I should have done in the first place. Never had a problem with the BOV but the wastegate was machined incorrectly. The available height for the spring wasn't enough and literally the spring would go solid and bind before the valve was open all the way. On the dyno I couldn't do anything to stop the boost creep and had to let out around 5000RPM as it was making around 15lbs on 93 octane at that point.

Took a minute to figure out but after I took the wastegate apart it was obvious. Turned the spring seat in the lathe and took off around 3/8" as the spring didn't quite fit the step and replaced the spring with an actual Tial. From then on it worked but it was obvious at the time that no QC existed from the lack of heat-treatment and lack of spring travel. I'd still argue that is the problem with chinese parts . . . tolerances are too loose/original model wasn't checked for fitment, the speeds/feeds are off so bad that the surface finish is garbage, and usually the plating/anodizing/finish is as cheap as possible.

 

I'm glad you posted this I also have one of thsee cx racing turbos 57trim 63a/r. It was on my d15y7 mini me on about 8 psi for over 5 years and over 80k daily driven miles making 175hp to the tires. But now I have moved on and am building a stock low budget b20b with p8r head. And kinda looking for information on setups and dyno graphs so I can see spool tines and hp &tq numbers. I have found lots of dated info but nothing recent. I think my set should net me anywhere from 240 to 280hp on 10 psi but data and setup are key. This is also going in my daily so max hp is not necessarily a key but max fun factor is one.

this is what I have so far.

the eBay turbo mentioned along with the cast manifold centered wastegate location.

3" turbo back exhaust
ls or b16 intake manifold with 60mm tb
large 18"x 12"intercooler with 2.5"piping

550 cc RC injectora with 255 fuel pump.
Thanks GOOD Review

 

@maohonda - If the CXRacing unit kept with the same measurements and wheel profile as the Garrett 55mm/75mm 57 "trim" unit that it copied, you'll see the same results as someone that has a genuine Garrett or Turbonetics from about 10-14 years ago. So, you're not going to find much information on actual "57 trim CXRacing Honda users". You can easily find similar setups here using that turbocharger at that boost pressure level on a similar SOHC engine with plenty of results. It's not going to vary much at all, nor has it for over 15 years.

 

I'm reusing the turbo on my stock b20 setup I havent found much data on b20s. A lot of people make b20vtec or b20 with large crower 404s but not many people writing about stock b20s I know my set up is able to make good power but I know there are limitin factors. I wish I could get a hunter turbo from STC but it just not in my budget right now. But I still like to compare my setup to others and see there results to mine to see if I'm headed in the correct direction and seeing how I never built one of these I don't have much data. I use Evans tuning dyno database quite a bit to see perticular setups and power outputs but to get feed back from people like your self Shodan is almost nonexistent lol. Your about the only person I ever get a response from on Honda-tech. Thanks

I'm just hoping for 240hp to the tire on 10 psi with pump gas.
