Lets play name that turbo

Ok so i got this turbo with my turbo kit and i searched all the #s on the google and found nothing. I was wondering if any of you know what turbo i have.
# on the air side
49178-5770 2a10a

# on the barring side of the exaust side
DUCM
22JC ? (that might be a C its kind of grinded off)

#on the other side of the exaust side
(Mitsubishi logo) 78-14300

So does any one know what one it is by any of these #'s?

Also to adjust the waste gate on this, do i just adjust the nut down at the end of the rod where its attached to the waste gate its self?

might be a Mitsu 16g or 20g. check those numbers against your turbo.

So, you bought a kit with an unknown turbo, post no pics, and we have to guess the make?

That is the name of the game :naughty: But well i do have a pic but its kind of small and really shows a bunch of nothing.

Its supost to be a hahn turbo kit. So it should be a 16g but i cant find the 16g on it any where. or any g's or b's or even an h.

Here is the picture of it, you will probly have to open it in your browser.

It looks like a 20g.

I would crap my pants if it was a 20g, but that is way more then i need. I can only run 10psi!!

Ok so i guess that isent all that important, but i dont have to know will it fit on a T3 manifold flange? it looks like its the same but i want to know for sure

yes.

That is a tdo6 20g compressor housing. Cant see the turbine inlet, if its round its mitsu, if its sqaure its t3. Cant tell you anything about the wheels from that pic though.

hey scott... email me your email address or go on AIM, i have a question for you! my email is: [email protected] and my AIM name is: RST Eclipse GST

20g hun, well thats going to give me some lag. Ahh well i can always put in rods and pistions in some day, then crank up that boost.

I sent you a e-mail mr rst.

20g hun, well thats going to give me some lag. :grinno: You have a V6, right? The Avenger?

I spool my 20g by 35-3800RPM on a 1997cc 4cyl.

No no thats my old car, i bought a talon. Maybe i should update that page.

20g is perfectly streetable, I didnt feel it was laggy at all, even with the tdo6H turbine wheel.... ~37-3800 rpm to 25 psi.

LoL well even if there is some ill get over it, It will always be there ready for me when im ready to pump up the boost.

Like i was asking earlier though, how can i adjust the boost? I know if i get a boost controler. But what can i do to the waste gate to adjust the boost?

You're asking... how do you change the boost without a boost controller? You can't. If you get an external wastegate, you can get different spring pressures for it, but there's no way you are going to want to skip a boost controller, that's where your power is at.

All right and the boost controler can just hook up to that internal waste gate? i dont know how they work i will have to look into it.

i dont know how that internal wastegate is goin to work at 10psi... usually the spring is pretty heavy and set for 13-15psi unless you have a really soft BOV that opens at 10psi to relieve the pressure but i see your using the stock 2nd gen BOV... how big is the spring in the WG? you might need to get a external WG so you dont get boost creep!



but anyways for the boost contoller hook up, T into the BOV line that runs to the manifold and run that to the boost controller, then run a line from the wastegate to the boost controller and your done!

It uses the bov to vent access boost? that is pretty inefficent, your engine has to do the work to produce it and it dont use it. I guess that would be ok for a few psi diffrence.

I think a external waste gate is out of the question right now.. i would need a new manifold and down pipe.

Well the boost controller install sounds easy enough, ill give that a go

These products are doing the same as the bov right just venting the access air? but i dont see how they can increse the boost past the wg srping if they are doing that

You are off-track. You aren't getting how each part works, but it doesn't matter. Just get the mods that are next according to the different guides.

You need a boost controller. Don't try to do something special, because it's not going to work.

Ok so your saying if i got one of thouse cheap $15 mbc it would work fine?

Probably, but you have to remember that most things are, you get what you pay for. A MBC under $50 bucks is going to be a semi-outdated method, the bleeder valve. JoeP and SBR MBC's and up have superior ball and spring ones. If you want to save as much as possible, the JoeP is probably what you want.

I think a external waste gate is out of the question right now.. i would need a new manifold and down pipe.


well then you need to figure out how to keep the boost down or dont never drive at WOT cause you will blow the piss out of your car... my suggestion is see if you can find a internal spring for very low boost...(i dont know who would have this cause i have always run a external wastegate, if you do find one you will need to port out your O2 housing cause you are goin to get major boost creep!!!) or get a external wastegate and vent it to the atmosphere! then you wouldnt need a new downpipe and you wouldnt have to port your O2 housing cause you would probably never see boost creep.

no offense, but dude, you really need to do some research on your own at this point. you have gone and bought a turbo that you had to ask what it was and are now asking some very novice questions. please save everyone a headache and do some MAJOR research.


do you even have a 4g63? from the way you said 'i can only boost 10psi', i would think not. and if this is in fact a 20g, good luck putting it on a 420a. i see a very blown engine in your future...

and please don't take this the wrong way, i'm not trying to bash you or anything, but i really think it is time for you to find some stuff out on your own... ;)

Actually, its minor research. Go to the DSM section at www.racingknowledge.com, I have a lengthy thread there on how BOVs, wastegates, and boost controllers work. Should help you get these things sorted out, so you can move onward and upward with this project. :)
