It's only been like a week. Still compressing...

Highly considering picking up one of these snails and holding on to it until I start throwing the turbo system together mid-winter. Hope to hear more good things as the days go on!

Any Updates?

I'm a little confused with the technical talk. If I ran one of these with a standard BP 1.8, how would it compare to my GT2554r? I'm looking for more power, without a huge loss in low end accessibility.

What sort of peak power could I expect to make?

How is the Chinacharger holding up?

Kaboom!

just kidding.

Its still doing amazingly in his car. Now that we put in a fresh bottom end hes getting great spool. Plus we found out that the chra is some form of ss casting. It has some coloring from heat and has no rust at all.

I'm running the tb28 in mine...very similar to this turbo and it's still holding up perfect. After 10k it has the same shaft play it started with, minimal. It hasn't leaked any oil or anything. The only issue I've had with mine is having to have the waste gate flapper door welded so it doesn't move a lot. For the price, it's perfect. If it goes out I was planning on going with the turbo from this thread.

I put one on a Rabbit track car Im helping a friend build and its seen some miles and a track day with no problems so far

Great news! I think I will be going the china charger route in my build.

How is the turbo doing? Is it not beeing water cooled not a problem? Did you use the v-band connector? If so, what did you do as far as the DP?

I am looking to build a NASA TTC/DD. I would love to drop 4K on a kit but if it can be done for less I would not mind. I am interested and am looking for the same power output and early spool.

Have a great day,
Jared

So far so good. Especially now that I have a strong shortblock in place. No, I did not use the v-band adapter as I already had a DP built for my standard 3-bolt wastegate.

I prefer the top-end I got from my real Garrett Super 60 T3, however, I do like that low-end torque im getting with this guy. Butt dyno says +20tq but -20hp. Dyno results on Nov 14th.

With mine, I had a local shop cut off the vband section and weld my fm begi downpipe. Everything fits perfect after doing that.

You can clearly see in this shot that I bolted on my original wastegate:

Are you running both ports on the wg actuator?

No, I'm not that cool. You can see from my log it's holding flat at 14psi with just a MBC on the top port.

I like the heat sheild

Just curious, which fitting did you use for your oil feed? I could never seem to figure out the size so whatever I used I just jbwelded the bitch in to keep it from leaking.

You are missing a bolt on your valve cover.

Thats where the other heatshield bolts to, it was not put on yet.

1/8" to -4an. Or in my case 1/8" to 1/4" cause it's close enough to -4an (4/16 =.25 1/4 = .25)

orly.

How's the build quality? I'm considering a Chinacharger myself. Holding up well? Did everything fit right on or did it need a lot of work?

Bolt on and drive.

I wish my avatar was a reality.

The engine bolted right up to it

I noticed that mine fits perfectly when the turbo is cold, but once it heats up the thing loosens up. I'm pretty sure I used the same fitting.

Also, it looks like you forgot to attach the last couple 200 cc's. Check your garage floor, maybe they are under the car somewhere.

it looks like even the garrett t3's are like this, but are there any boost creep issues from the design of that wastegate? seems like the exhaust gas has to make a hard 90 right out of the port...

Any updates on this?? is the 14th still happening?? Im strongly considering selling my 2860, get this particular turbo, and use the rest of the money to pay some bills and finish up my built.

yes, will dyno this Saturday.

Too bad the 2860 has a smaller flange than this...but you could get something like Phil and Tyson has...

IRCC, Phils turbo was about $300, Tyson got his from Begi, and Im looking for something under $200 like the one you got. Ill be more than happy with 240whp till I can afford a built engine. Where do you think you stand right now, power wise??

my guess is 220tq/220hp @ 13psi...my butt is pretty good to, we'll see.

It took 16 psi on my turbo to make 242. Big risk on a stock motor.

240 is a big risk on a stock miata motor?

Sigh.

Oh damn I see. Brain, from what I read I assume you're at about 14psi. I could settle at 220~230 for now. Phil, Tyson's turbo is a 2854 right??

WTF phil...no

Why do I get the impression Phil doesnt like me?? -_-

A#1 - knocksensor! Seriously. I was going through motors like underwear till I got one. None since, except from a bad coolant hose.

I don't know where the 1.6's run out of steam, but I think that's in the upper limits of reasonable - from stuff I've heard from FM.

Really thought I was making more torque, I guess the fact I'm making it so much earlier threw off the butt dyno. Dunno if ill keep it on or switch back, but it's running pretty solid.

here's the comparison of the Garrett super 60 trim to the ebay 50 trim.

http://www.boostedmiata.com/gallery2...serialNumber=2

same everything, just a different turbo?

also i didnt thing garrett made a "super 60" just a 60 trim.
correct me if im wrong but i thought it was turbonetics with the SUPER

No, the Super 60 wheel came on some old dodge I cant remember, maybe the Grand National as well.

It's pretty much the difference between the 2560 wheel and 2860 wheel, it has a .07" larger inducer than a standard 60 trim T3 wheel. Consider it a 62 trim...

The 60 trim wheel can support around 35 lb/min and can compare to a 2560 wheel.

http://www.turbobygarrett.com/turbob...-1&4comp_e.jpg http://www.turbocharged.com/catalog/...mages/Fig4.gif

The 50 trim wheel can support around 27 lb/min and it more comparable to a 2554 wheel:

http://www.turbobygarrett.com/turbob...71-3comp_e.jpg http://www.turbocharged.com/catalog/...mages/Fig3.gif

I was hoping with this wheel, not only would I get faster spool, but more mid range torque than before. I knew I'd lose top end. Still drive damn nice, faster spool, but just a loss after 5.5K. If I want that extra top end back i just need to add a pound or two, no biggie.

Turbonetics made the super60 for dodge as part of a 300 hp package sold by dodge for the turbo 2.2's. I think it may have had something to do with their shelby relationship too.

That's a nice torque curve! Congrats. Really, I like how that comes on nice and early.

You know, maybe some headwork is called for. Do you have any? The simple stuff like deshrouding and port matching will help your top end - making more power on less boost is what's up.

If you have EBC or ... Are you taking your wastegate signal at the turbo? That could be it.

Having that extra 30 ft-lb of torque at 3.5K makes a world of difference. This is why I'm unsure I'll switch back.

But im still unsure what that large ass turbine blade is doing, so I might go swapping things around again. Put together a true Garrett T3 50 trim with real genuine parts and see how the effects it.

http://boostedmiata.com/turbo/ebay/DSC_0011.JPG

look how much bigger the ebay inducer blade is, the exducer is the same.

I has the above mentioned headwork.

Running MBC only, EBC is to switch from wastegate to MBC, it's spooling the same on or off.

Taking signal from after IC.

It is if you have sub par tuning skills.

Yes, unless you know what you're doing tuning wise.

Don't be gay..

Yeah, those are my ideas for EASY top end losses. Do you have EBC on the MS-I? I think you're right, more boost will fill in the top end. It could be a restrictive intake making you lose top end due to extra heat required to ram the air through....

Restrictive exhaust might possibly be killing top end, but I think you're car is fairly well put together.

Nice!

setup is the exact same but for the turbo. it simply fails to hold the torque after 5.5K like the old turbo.

So, you're saying bigger turbos make more top end power, and smaller ones spool quicker?

We should write the President! Perhaps this could be our new secret weapon! :-P Do the maps support this, that you're running out of steam up there?

Thanks for the good testing, the results were pretty good for the price point.
I for one hope you keep with it as i would be interested in your long term opinion on reliability.

Alright another guy with a chinacharger. I didn't go as small though. I have the 57 trim. Gonna have it on the dyno in a few weeks after I finish the rebuild and break it in

pretty much, the wheel should still be able to support around 220-230rwhp, but i still was hoping for a more robust mid-range. It's really hard to say what effect the turbine has. I might throw in my true 50 trim come spring and compare for shits and giggles.

turbo might be pulled tomorrow. update tomorrow.

so...tomorrow?

What are you going to do with the chinacharger?

Will have to compare numbers. Mine 'should' be finished today and hopefully have some dyno plots by Sat for the MSPNP tuning. Very similair turbos, .42A/R with a 50 trim on a T3. We ran out of room with the WG housing plate (with the 3" down pipe) so we set it up for an external WG.

False alarm. I had been fooling with the wastegate over the weekend and I fitted a new cat and proceeded to failboat.

I was hearing a weird rattling noise if I blipped the throttle and the boost was very slow. The boost onset was due to my improper plumbing of the MBC, I used the top port of my wastegate without thinking when I put things back together. The noise was a combination of two things, first the cat I just installed has a leak at the flange so I need to redo the seal, and second, I had my wastegate arm too loose and the flapper was rattling.

All is still well.

Log the results when you get your "close" port hooked up on that actuator! I'm waiting for improved spool and acquiring boost target sooner. :D

I dunno how I can really improve spool. I need to remove the MBC and try this PID closed loop EBC business.
