It would be great if those who have worked with this turbo made a new thread with "how to" solve the common issues the turbo have. Etc:
-New oil lines (where to buy, how to fix).
-How to tighten the acuator
-How to replace the acuator
and other fixes that might need doing on this kind of turbo.

I know there is some pictures and how to`s in this thread, but its a 64pages long thread, and not very easy to find out what issues this turbo have, what need doing, and what might need doing.

I have followd the thread some time, and have read all 64 pages. There is alot of information in this thread, i just think someone should sort some of it out.
yeah good idea, On other news ive installed my hot side pipes, i now get wheel spin coming onto boost in the dry (more boost at lower rpm aswell!) the response has picked up lots, replacing the cold side of my cooler piping soon (its 2" for 50cm from the turbo then opens up into 2.5" until the cooler, after the cooler it will reduce to 2.5" or 3" (haven't decided yet) until the throttle.

I accidentally left the vacuum line off my controller and found out what 23psi is like... which is sideways., luckily the car hit boost cut (safety feature not annoying boost cut) I need to take it for a drive where i can open it up but its defiantly an improvement over before. Its funny I keep finding reasons for the slow spool and most of them have nothing to do with the turbo its self.

I would be real awseome with some pics etc for the how to`s, if any one have this kind of documentation.
Im glad to hear that your geting some good boost with ur turbo. I might buy one soon, as there is only 50% tax on Decembers salories.

Keep up the good work :)

If you have 7M and buy this turbo, just send Grimsta from Zankoku a msg telling him you need oil-lines + fittings for this turbo, and he will hook you up :)
Then it bolts up :)

I think I will be e-mailing CXRacing personally as well and ask them if they've taken any actions as to fix these problems.

However, one key question still remains to be answered: to those of you with this turbo, how reliable do you think it is so far?

0 Turbo related issues, No shaft play No smoke No funny noises. about 9000km on the clock since installing and most of that was WOT :p The turbo is reliable IMO Boost control on the other hand needs some fiddling.

I took a video with new pipes, its short and crappy. i'm making a compilation video just need some out of car video to top it off.

It started wheel spinning pretty quick and was on the limiter. as you can see not exactly slow, FYI - 105km - 95km (60mph~) my speedo's out after swapping to a R154. Boost comes on very quickly, this run was at low boost (13psi)

I have about 2k miles on this turbo, and it is how it was when it was brand new. no play, smoke, etc.. i agree with paradox, The only main downfall with this turbo is wastegate control.

I am interested in seeing how it would perform with a 3.73 rear instead of the 4.3 ......... The load of a 3.73 might do some wonderfully things.

May I have your permission to send your information to CXRacing? I'd like to write an elaborate e-mail to them since you've mentioned you're quite busy. Since the remaining problems are on their end, it'd be nice to give them a constant follow-up with the few details that need to be sorted. If they are truly willing to sort out the issues, then I imagine they don't mind being poked constantly.


Heck, I'm saving up the money I'm making by selling old parts to get one of these as well. Cleaning the stock MK3 seats in an apartment isn't as easy as it sounds :/

Go for it :) I've already contacted them about the issues so that they may correct them however that was a while ago, i made some more adjustments to my car but havn't been able to test yet, We've had some massive downpours down here and a bit of flash flooding. in the wet 100hp is faster than 400hp :p

Yeah I'd be interested to see the results as well.

I've put my car off the road for now until i can get it back to the tuners, its leaning out under high boost low rpm conditions (high rpm high boost is fine). I can see full boost of 20psi in first gear now. There is minimal lag in my set-up any more which I'm really happy about. I'll be replacing the rest of my cooler piping them sending the car back to the tuners in the next 3-4 months. No more updates till then sorry guys!

Hey Paradox did you replace the wastegate with the 2-Port Turbonetics to get 20psi in first? Do Tell!

I had a valve seat come out of mine and have to flatbed the car 200 miles this weekend to get it to my shop where I can pull the head before winter. Really hoping the bore/piston is okay. The saga continues for me...

nope, using the waste gate that came with it. I simply fixed more leaks and replacing alot of rubber hose with stainless piping. The boost control still could be refined but its not uncontrollable any more, Having said that i have not had to the chance to take the car anywhere i can hit high rpm in third gear as i do not dare do anything that stupid in the suburbs..

My car is now suffering from mass traction problems but this just proves boost is coming on alot earlier :), looks like i need some wider tyres after i get it back from the tuner.

I just got my own T61 about an hour ago. And I have great news about one detail at least. The WG flapper doesn't move around anymore. Apparently they fitted it with a longer shaft and spacer to prevent it from moving to either side.

The kit still includes the cheap bolts that will break under use, so it's still a great idea to just go to the shop and get some grade 8 bolts that can handle the job (also still incorrect size).

Unfortunately, I can't tell if they've solved the weak WG spring issue as I don't have the equipment at home to test it out. I'll *try* to see if one of the local turbo shops can test it out for me real quick on Monday as I'm busy the rest of the day. I would also love to open up the cold side to see if they've done anything to seal it better but I would like to know what's the torque for the bolts holding it together for when I put it back.

so i talked to a fabricator locally who does some insanely good work at an insanely good price and now have a question since he says its simple/easy for him to do.


i HAVE NOT READ since my last post and am about to walk out of wifi so im typing this fast, did you guys solve the internal gate boost control issues? because i got a fabricator willing to drill and weld on a tial WG bung onto the stock CT manifold. and he said it was simple for him to do.

so basically its like being single but stock at the same time :D

looks the same as mine, it didn't come loose until after a few heat cycles. id still secure it with a grub screw! having said that they modified the flapper arm so it wont catch on the housing as easy! its nice to see our feedback taken seriously!

Ah, I will secure it for precaution's sake then. Haven't had a chance to test out the WG pressure though.

A note to anyone else that buys this turbo. Not sure if it has been discussed, but you might need to rotate the center section just a tiny bit counter-clockwise (looking from the front) so you can fit a flange and AN fittings. The exstension from the WG is in the way and will not let you place the fittings. Reall easy to do here. Just remove the WG (1 clip and 2 bolts in the base), loosen the bolts around the compressor housing just a bit, and then loosen the ones holding the turbine housing.

Is this on your car yet? I'd like to hear your impressions of it, and see if they've made any changes.

I'm think about buying one from Zankoku, but I'm not sure this the route I want to go.

As am I. Sounds like a decent alternative to a CT26 60-1 upgrade...I just want a stockish looking snail that'll do 400-500 whp reliably. This seems to fit the bill really well, I may have to budget it into my build.

Yeah it could be, but after I read through all the post last night these wastegate issues sound like a royal pain in the ass. 411rwhp @ 16psi isn't bad though, especially if paradox616 was having issues.

If CX racing fixes the known issues/quirks then I might even use my 1JZ w/ a Stinger as a guinea pig to see I what I could get at 18 on a dyno :)

Ok so read threw page 30 on this turbo my eyes are wore out. Should I buy one I'm sry I know this has been answered. But this has been one awsome thread to read. I'm am for sure goins to to have to do a rebuild on my motor so if I build the motor right will this turbo hold up.

As far as quality and the reports here, noone's had any complaints. What hasn't really been answered is performance beyond 1bar...but that's really a matter of time more than anything else, I think.

Turbo really looks promising, especially for a bolt-on affair. Yes, there are wastegate issues, and some lag problems that require some special attention. But, that's kind of to be expected...Toyota never meant for us to design and produce our own turbos.

I just got one to play around with. My JT62 is being used by a friend in meantime(his car had to be raced). I am going to get Jeff from notrice.com to inspect and fix the wastegate issue when he is up here next week in MD. I got the correct oil lines and inline filter to run with it as well.
My best time with an SP61(which is basically the same thing) is 11.69(most runs 11.9-11.7) at 123 MPH with meth on DRs at 3400 pounds an 22-23 psi with high 1.7 and low 1.8 sixty foot times. I have to retune my car with this smaller turbo but I bet I can hit high 11s easy with it if wastegate problem is fixed. The question will be how long will it live at 17-20 psi of use on the street

I'll be happy if I know I could manage a hair north of 400 at around 1bar or so. Which has been proven, so far, and with tuning and mechanical problems at that. Big question is longevity at this point...which boils down to attention paid to balancing, bearing quality, and material selection.

My cars getting some love soon and going back to the tuners for higher boost (20-22psi)

Currently i get wheelspin mid first gear, all of 2nd and half of third. I'll be interested to see the numbers i can get out of it.

A lot of good info here. I bought the turbo and going to fix the known issues, but one thing I didn't see discussed is a brace for this turbo (like for CT-26). I think it's important as this turbo is heavier than CT-26. Has anyone made one for this turbo?

so what exactly are the waste-gate problems? sorry for the repetitive questions its just so extensive to read through 67 pages to find the answers, any mods need to be done beside re routing the water, or is it water and oil cooled?

I have followed the tread for the last 6 months. just got some tax $$ so soon as I get my na-t motor built I AM buying this turbo. for the $ it looks like the one to buy if you can use any tools.

props to you guys that have posted the numbers. hope to post mine in the next 2 months. any one want a 78 celica 22rturbo. $1500 funding for my supra.

still very skeptical guys cx racing has some decent parts but its still a china turbo and so so hardware and accessories i would just use those and find a better turbo to run with it. turbo just not something to cheap out on. Why do you think everybody's still doing ct upgrades i stay either do that or if you want the same amount of power as the cx racing setup just go the already proven greddy 20g setup same power but way more reliable....

And whats the price on the Greddy 20g? Last time I seen it, they where 2k brand new... I've never had an Greddy 20g but to be truthful, if your gonna spend over two grand for a brand new turbo. Why not order a 60trim HKS Sports Turbo? and or LIPP Boss Jr. or Boss Sr turbo? They're all bolt on's they can all yield 400hp-600ish depending on the turbo, but all start at $1500.

Okay, I just installed this turbo and took it to the dyno. It did have some problems... My compressor housing is leaking but only at 18 psi. It made to 20 psi once but after that it couldnt crack 18 psi. Also the wastegate had a hard time stabilizing the boost, cause the tuner said it was struggling to say the least. However with all of these problems, it put down 411 rwhp at 20 psi and 390 rwhp at 18 psi. So not too bad of numbers considering this was on a dyno dynamics which I found out compared to a dyno jet can be anywhere from 12 to 15% low. So account 15% and it wouldve made 472 rwhp at 20 psi.

This turbo is definitely capable of putting power down, it just seems that is has a hard time holding it. With the compressor housing leaking, it is extremely laggy as well. Full boost seems to come in at around 4500 rpm, so not much of a powerband to work with.

After reading a lot of this thread, Ive seen suggestions of using RTV to seal the compressor housing. I wouldnt mind trying this to see how it works as long as someone could post some pics of EXACTLY where to put it cause I only see pics of the compressor housing removed, and I definitely dont want to mess that up. Im assuming that with the compressor housing sealed up the powerband should shift a bit lower since the turbo shouldnt be working as hard to achieve the same boost.

A lot of discussion here brings up this turbo compared to a 57 trim. Well I swapped my 57 trim for this turbo, and I can shed some light:
1st) The 57 trim definitely spools much faster and has a nicer powerband (compared to my T61 with a leaking compressor housing)
2nd) The 57 trim is much more convenient when it comes to plug and play
3rd) The T61 will make more power (not talking about powerband, just numbers) MY setup 378 rwhp @ 15 psi (57 trim) vs. ~470 rwhp @ 20 psi (T61)
4th) Price is about the same for both if you buy new, I bought my T61 used with lines for $400


IMHO, I would go with the 57 trim for streetable power, only because I still have some playing to do with my AVCR to see if I can keep this thing on the road. I plan on going to the track to see how it can manage there with some adjusting of the AVCR. My fastest ET with the 57 trim was 12.67 on drag radials. Im running street tires now, so I'll pray;) I would imagine that with the compressor housing fixed, that I would like the T61 much better hoping that I could move the powerband somewhere that is manageable.

Anyways, sorry for the long post, but I wanted to post some info that I know some are wondering or speculating about. Again, if anyone has any ideas on how to fix the leak in the housing, Im ALL ears!!

Pretty impressive to make those numbers with a boost leak, which usually robs power as well as slowing spool like you mentioned

Thanks! The tuner showed me on the dyno sheet where the boost fell off and he said it was on its way to making easily another 20 to 30 horsepower, but it couldnt hold 20 lbs. If that was the case maybe this turbo would be capable of 500 whp. I have been looking all over the net researching how to fix a leaky housing. I found some interested threads on the DSM forums about using the RTV, they swear by it.

I found some pics of how they are doing it, and I may end up doing this in the next couple of days. I just dont want to take the turbo back off, so we'll see.

I know with some turbos you can take the compressor housing off with it still mounted to the manifold, should just be a few bolts on the back of the housing
