What Turbo is this? [Merged] Turbo ID Identification

[Chicken Patty]

I just have to find a t3 flanged manifold on the classifieds for sale.. my buddy owed me a favor. I know own a T04E54 and a HX-35

You can also get a BEP housing for the HX-35 and bolt it on to the stock mani/o2 housing. ...Or whatever mitsu flanged manifold you may have if you do.

I bought this turbo from a buddy who had it on his galant in japan. He said it's a 16g/20g hybrid. What do you guys think? He said he was making over 400whp with this turbo when he was stationed over there. Any help is appreciated.

Okay so its like this.
I've been searching around the internet and forums looking for a few answers. I can't word them correctly to search for it. Honestly I have, and I've been at it for about a month now. As I'm working on a project for school, using a dyno program. But my questions aren't quit answered, and I know they are simple.

1. What BOGGLES me, how can a another company, make another companys turbo? Like turbonetics making a t3/t4. When the t3/t4 (from what i read) are garret terms. I under stand ### it means. t03 turbine witha t4 compressor housing correct?
examples: people making 16g's, but they arent mitsubishi? What are they using to make it a "16g" and what are they using making it theirs? Catch what I'm saying?
- then theres some that Ive only seen being made by one company.
Example, hx35, ive only seen being made by holset (maybe I just missed something) If so, is there a reason only Holset makes it?

2. Lets say I want to find a turbo for a setup that will be running 15 psi. The only part of the compressor map I should be worried about is the 2.02 pressure ratio line across the map correct?
This is because atmospheric pressure (for me at sea level) is 14.7, my goal is 15psi. So i add the two, and then divide by atmospheric. Giving me 2.02, correct?

3. Relating to the above (#2), I also want to make sure its always out of surge.( at idle, boost threshold, and max rpm) Meaning I want to find out how much air my engine is actually taking in (needs) at a certain rpm then plotting that on the compressor map. So that would be
[(rpm x displacement) / 3456] X (vol. eff. .....ex .90 as 90%?) . But What volumetric efficiency do i use? A naturally asperated vol eff? Meaning around 95% for a 4 valve head. Or a volumetric efficiency that would be in boost (100% or more)?

4. Also I understand that Garret's measurements are, for example: GT3071 would be a 30mm turbine inducer, and 71mm compressor exducer. however then the exducer on the turbine and inducer on the compressor can change. Leaving you to have varients of the gt3071? bigger or smaller compressor inducers, bigger or smaller turbine exducers. Correct?

5. If number 4 is true, do all companies do the same?

6. Is there a write up of how each turbo company writes out their turbo sizes, dimensions, trims, etc etc? Like looking at the name hx35 doesnt really tell you anything about the turbo does it?

7. Now then I see just a T3 turbo. Is that its own turbo with its own turbine and compressor dimensions. And from what I read, thats again a, Garret errrr "thing?" How can another company make a T3, or T4 etc etc, turbo? Does it vary much from the garret T3, T4, etc etc?

8. So lets say I see an awesome t3 turbo, but low and behold its not a garret T3 (again, assuming what I wrote above is the way I think it is), does the compressor map vary much from the Garret T3

9. If my computer dyno program can show me Vol. Eff., I can see where boost comes in at correct? it would be where Volumetric Efficiency jumps past 95-100 % Correct?

Im sorry if these questions are vague or not, as I'm not sure myself
And I understand some of the last ones maybe far off, If the others have a different answer.

I really tried to make this as clear, and grammer friendly as possible. These questions have had be strung out for the last month, month and a half.

Any help, write ups, or other turbo know how... would be GREATLY appreciated.



Thanks So Much!
Andrew

Hy-35 or hx-35?

 

[JusMX141]

Some of this can be answered here:

Otherwise, way too many questions for me to even begin to consider answering right now.

 

[JusMX141]

I bought this turbo from a buddy who had it on his galant in japan. He said it's a 16g/20g hybrid. What do you guys think?

TD05H 20G with a Subie-style cover. Doesn't appear to be a MHI 20G compressor wheel, however....definitely an aftermarket imitation.

Hy-35 or hx-35?

Neither. HE341.

This thread should be renamed to something like "jusmx41's turbo identification thread"

. You're a beast man! Haven't came across anyone who knows turbo's like you do Justin!

 

[KazooGS-T]

Yeah, questions all over the place. The easiest one to answer right off is: T3 and T4 turbos, that's the type of exhaust housing (and flange that you will need on your turbo manifold). They also vary to different types for specific manufacturers, which will only allow that type turbo to bolt onto the manifold being used. T6 turbo's are generally used on big v8's and diesels for example and will not bolt stright onto a T3 flange.

Here is a good link if you want to learn about Garrett Turbos TurboByGarrett.com - Turbo Tech101

They have 3 of those "courses"

I'm going to skip around a bit because it's 3am and my head hurts from the ten PM's since 6pm that I just responded to.

1. What BOGGLES me, how can a another company, make another companys turbo? Like turbonetics making a t3/t4. When the t3/t4 (from what i read) are garret terms. I under stand ### it means. t03 turbine witha t4 compressor housing correct?

Example, hx35, ive only seen being made by holset (maybe I just missed something) If so, is there a reason only Holset makes it?

What can I tell you...imitation is the sincerest form of flattery. Unfortunately, when Turbonetics and PTE are copying Garrett's, they're copying a center housing that was designed in the 1960's around turbos meant to run 8psi. This is the reason journal bearing PTE's have so many issues when pushed beyond the realm of reliability.

Think only Holset builds HX35's and HX40's? Take a look at the Chinese garbage on eBay sometime.

4. Also I understand that Garret's measurements are, for example: GT3071 would be a 30mm turbine inducer, and 71mm compressor exducer. however then the exducer on the turbine and inducer on the compressor can change. Leaving you to have varients of the gt3071? bigger or smaller compressor inducers, bigger or smaller turbine exducers. Correct?

3071's do not have a 30mm ANYTHING. The GT30R is a series of Garrett turbocharger much like an Eclipse is a series of Mitsubishi car.

Generally-speaking, GT25's and 28's have a T2-spec inlet flange on the turbine housing, GT30's, 35's, and 37's have a T3-spec inlet flange on the turbine housing, and GT40's, 42's, and 45's have a T4-spec inlet flange on the turbine housing.

5. If number 4 is true, do all companies do the same?

No. Every company has a different way of labeling their own specific turbo, and it makes me f*cking insane.

Example: The PTE 5031E is a 50-trim compressor and a T31 turbine. Perfect. How the hell come the 4431E is a 60-trim / T31 combo and the 3431E is a 57-trim / T31 combo? WHERE are you getting 34 and 44 out of those compressor wheel specs if the 5031E uses the compressor trim as the first number in the listing?

Instead it should be 5731E and 6031E, but oops...we already call the turbo with the 60-1 compressor / T31 turbine combo the 6031E.

6. Is there a write up of how each turbo company writes out their turbo sizes, dimensions, trims, etc etc? Like looking at the name hx35 doesnt really tell you anything about the turbo does it?

Such information does not exist in any one location which is probably why I get 15 PM's a day.

7. Now then I see just a T3 turbo. Is that its own turbo with its own turbine and compressor dimensions.

Yes.

8. So lets say I see an awesome t3 turbo, but low and behold its not a garret T3 (again, assuming what I wrote above is the way I think it is), does the compressor map vary much from the Garret T3

Probably....all Chinese and Turbonetics imitations of Garrett turbos must either used Garrett-licensed parts or the parts cannot be interchangeable with a genuine Garrett due to copyright laws.

Here's some confusing info- there are companies that can build and sell a compressor wheel identical to a Garrett 57-trim which is interchangeable with the factory wheel (fits genuine turbos), but they cannot advertise it as genuine and can only state it replaces the factory wheel. Now as a new turbo seller you undoubtedly can't buy Garrett-spec wheels and put them in a Garrett-spec turbo then sell it as an identical Garrett turbo without dealing with some type of copyright laws, which is why we're seeing tons of shit like "T3/T4" and "T04E" pop up on the Chinese garbage. They're branding turbos after models...like building an entire knockoff car identical to a 2G and branding it as an Eclipse.

Guys, that all helped sooooo sooo much.

I read all the garrett turbo 101,102,103 multiple times.

"3071's do not have a 30mm ANYTHING. The GT30R is a series of Garrett turbocharger much like an Eclipse is a series of Mitsubishi car."

Okay, I think I made an assumption off of this statement

"Let's use the GT4294 as an example. This unit has a GT42 frame size turbine coupled to a 94mm (exducer diameter) compressor wheel."
But i was right about the compressor side. Which you could still have different trim, 94mm compressors. (as many as the company have designed)

Now do they only have one trim 94mm compressor? Or is there multiple? Do other companys do the same for their compressors?

And, for lets say the Gt42 frame size, can have different trims to it as well. Still remaining a Gt42 inducer, but varying exducer for different performance?

Then there are different wheels, I kinda understand that.


Now what about the hybrid turbos? Can someone give me an example and "definition" of them? explain them?
So a T3/T4 hybrid is thus. A garret gt30 turbine, with a t4 compressor?


And if someone just tells me the trim of their turbo, that still tells me nothing. Cause my 16g is a 60 trim, but their are also huge turbos that are 60 trims correct?




Im sorry, I really thought I organized the first post well
If someone lives in my area, I would greatly appreciate getting together, and talking about it all. Id even treat them to a dinner or something.

Thanks again guys!

Whats the best way of feeding this puppy with oil.. Head or OFH? Also will i need a restrictor?

What is the best way for making a exhaust for this turbo off a v band some welding to make a a flange i guess eh..

How come this turbo is only oil feed and not coolant?

Find the right size flange and buy it, then weld up an o2 housing or downpipe to fit..

How come this turbo is only oil feed and not coolant?

Diesels operate at cooler temperatures where oil coking is barely an issue.

 

[shay4g63]

won't this present a problem in my talon? with just oil feed?

 

[JusMX141]

Have you even looked at most of the aftermarket turbo setups used on our cars? With the exception of ball bearing turbos, once you abandon a turbo in the OEM platform you're generally not going to find one with water fittings.

Please note this thread is for turbo I.D. only, not tech questions regarding turbo installs.

 

[Nic_S]

I am just trying to figure out what turbo this is I was told it is a Trust Turbo I'm thinking it may be a TD05-TD06 hybrid as the compressor housing is stamped 49179-53030 but it is also stamped 49178-05120. The exhaust housing is also stamped with the mistsubishi sign and 78-14300. The inlet size is 53mm. I'm just after the specs of it 16G 18G 20G etc and whether it is suitable/will still make good power on a 3.0L 6 Cylinder (Nissan RB30) Any help would be much appreciated as I can't find any information anywhere else.

If I had to take a guess I'd say that's a 20G.

 

[JusMX141]

Td05h 20g.

 

[boost1995]

Ok so first off i wanna say that i read the first 12 pages of this thread Word for word and i am positive this is a 16g turbo that i bought from a guy yesterday but i am not sure of the manufacturer or if its a evo 3 or a big/small 16g. Can you guys give me your 2 cents please? Also the compressor housing has no writing on it and the only thing on the hot side is a AR .70. Thanks in advance.

 

[Chicken Patty]

Kinda looks like one of those Ebay knockoffs. Original MHI 16's whether small/big/ or EVO 3 look like this on the comp housing. Of course the serial #'s change depending on which model it is.

[boost1995]

I was thinking the same. There are no numbers at all. I got it for 100 bucks and j plan on using it till it dies or i can afford a new setup.

What is the bad about the ebay knock-offs? Do they build boost and hold the same as a mhi 16g? Do they go to crap faster? Ive never had any experiance with one so idk.

On the.bottom of the wastegate it has a sticker that say MDU. I googled it and didnt find much. Anyone know anything about this company?

Don't have any experience neither, but they are definitely not the same quality. I've heard that as long as you keep them at low boost levels they actually last okay.

I know Justin had experience with a ebay 35R on a friends car I believe, maybe he has more to say than me.

That thing is so generic it doesn't even have the markings on the cover that other knockoffs do.

Strangely enough, that doesn't appear to be an Evo III-spec compressor wheel....the "hub" area of the wheel is too large. Looks like a copy of the Big 16G wheel instead.

 

[boost1995]

Ok i did a bit of research before i left work this morning and tore the comp housing off and measured the comp wheel. The exducer measured 2.675 and the inducer was clearly 1.905

then i went back through the first nine pages until i found a post where someone posted a pic of the evo 3 and b16g o2 flange side by side. In this pic it shows on the evo 3 the outside of the flange is round versus a streighter flange for the b16g.

So granted this turbo i picked up is a knock~off, it does apear to be a evo 3 g. My question is~ do u guys think this thing will be halfway reliable and will it hold good boost? I do plan on bolting it up either this afternoon or tomorrow. Also a question for the guys that run evo 3s....what do u push for boost and how is the spool on it?

Your profile doesn't list any fuel mods? I would keep boost under 12psi.
