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)

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.

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.

big jim 10-24-2009 09:33 PM

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...

buffon01 11-11-2009 01:01 PM

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.

Braineack 11-11-2009 01:03 PM

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...

buffon01 11-11-2009 01:23 PM

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??

Braineack 11-11-2009 01:28 PM

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.

buffon01 11-11-2009 01:42 PM

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??

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.

Braineack 11-14-2009 05:48 PM

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.
