Questions for Justin...

[Kyle_T]

Does the locating pin on 14b/16g's just help to line up the turbine housing or does it prevent the housings from spinning? If my pin is broken off should I do something about it or will it be fine?

 

[JusMX141]

Justin can you send me the compressor map for the 13g and 14b.

Also how much would it help to have a 7cm turbine housing on both..I know you can run the 14b to 20psi, but what about the 13g?

The 13G has a TD04 turbine, so you're not putting a 7cm housing on that POS.

A 7cm housing will help a 14B only if you're pushing the turbo to it's limit where you'll gain a tiny bit of turbine flow from decreased backpressure.

You can try to push the 13G to 20psi, but it will never hold it beyond 4500rpms or so.

Does the locating pin on 14b/16g's just help to line up the turbine housing or does it prevent the housings from spinning? If my pin is broken off should I do something about it or will it be fine?

It keeps perfect alignment for assembly and doesn't allow the housings to spin should the v-band come loose. You'll be fine as long as you align the points where the pin should be, and the v-band stays tight.

I couldn't find the spool rate of these turbo's but I did find a site that have pretty good info concerning mits turbos..You should probably check it out.. Stealth 316 - Turbocharger Compressor Flow Maps

I asked about the turbo's because I found a 13g on CL tonight for 75 shipped or 50 picked up..But I'm no driving over two hours to pick up a turbo..

That site has been well-known for quite some time.

Why waste your time with a 13G? It's wheel spec is no bigger than a T25 and it actually has a smaller turbine housing a/r than a T25....so you'd literally be better-off using a T25. Leave the 13G's for the 3000GT guys.

 

[Bud92gsx]

Why go back to the 13g, instaspool..And I might return my car to stock untill I can afford the upgrades I want..Since my 5speed eprom decided to take a shit on me yesterday..

You know Just as well as I do that one of these days my ebay 16g is going to break..I want to have a backup ready to be bolted on.I know what your next two questions are..Why not look for a 14b, that's a very good question that I don''t actually have an answer for..

And the next question after that is going to be, then why the hell haven't you sent me that blown small 16g you have sitting around..That alone is still not at your place because, lack of funds..I talked to the guy I semi sold my talon to today..And he says as soon as he gets it running, I'll be started to get paid..He still needs to mount the new alternator, and new WG..And the car got pushed off to the side of the garage because he has been working 2 jobs lately, and the guy who owns the garage is prepping his truck for a new paint job right now..

 

[KevinRR]

I was planning on picking up a MHI 20g and swapping out the housing to 16g. So I can bolt it up to a 2g manifold. Do I have to modify the housing to fit and can I still use the internal waste gate?

 

[JusMX141]

Shouldn't have to modify anything- and you'll have a stubborn time getting a standard 14B/16G actuator to mount to the 20G's cover...so make sure you get a 20G that comes with an actuator which fits it's cover.

 

[Alex7747]

Okay you dont have to answer this if you dont want to...
How bad of an idea would it be to run without a bov? How bad would it be for the turbo(16g). I know it will cause compressor surge. Will that totally kill the turbo? Because i remember reading a thread once where a guy took his bov off and he was saying it was okay??
Thanks

No it would not be okay... You would destroy the turbo, can you imagine doing 100,000mph and then basically stopping on a dime?

Low boost (under 8psi) you'd probably be fine and never notice any consequences. There are plenty of turbo cars on the road operating at under 8psi which never had compressor bypass valves from the factory. Anything over that would pretty much require one for trouble-free operation.

You cannot hurt a ball bearing turbo from surge at streetable boost levels because the shaft is constantly supported by the bearings. Extremely high boost surge will twist, bend, or break the turbine shaft.

sweet thanks!! And Thats why you're the man!
the reason i asked was because my cheap ebay bov is leaking and i was wanting to remove it all together. But ill just buy an hks. Thanks for the info!

 

[JusMX141]

Buy a good used 1G valve for under $30, recirculate it, and don't look back.

 

[Alex7747]

Yeah but i already have a ssqv style bov(ebay) and if i just buy the real hks ssqv bov and recirculate it, it be better in the long run?
After i upgrade the fuel and get dsmlink the 16g is going and im getting a holest ..if all goes well

 

[97gst_spyder]

Ok, Justin this has been killing me for the last month or so.

Could you please explain (briefly) the pros/cons of the following setups...

18g comp in e316 comp housing/tdo5h 7cm
20g comp in e316 comp housing/tdo5h 7cm
18g comp in e316 comp housing/tdo6h 8cm?
20g comp in e316 comp housing/tdo6h 8cm?

I'm planning on upgrading again from the 14b. I dd my car so I really want more low/mid range power.

Everything I find has so much bs injected into the threads that I never get a clear picture.

Thanks!!!

 

[1990AWD]

Justin, I would like to know the airflow numbers of this turbo please.

To summarize: Garrett T4 TO4E 60 trim.
4'' compressor inlet - compressor exducer: 75mm, inducer 52mm
exhaust housing exducer 58mm, inducer 73mm

Thanks!

Alright, I know this may be just a little off the topic being that this is related to a 3000gt and not an eclipse but a friend of mine asked a question about rebuilding the turbos on the car he just picked up until he can eventually afford to rebuild the entire engine and do a considerable step up in performance. Right now he is trying to get the engine back together and running so that he can figure out what is wrong with it. He was told that the block was cracked however from what he is telling me it just looks more like the block is worn out and needs to be rebuilt. ATM he is going to rebuild this one if nothing is actually wrong with the engine and drive while he locates another block and builds that one up for a swap in. I had mentioned to him that there was someone on tuners that knew quite a bit about the turbo rebuilding so I figured i would ask about some upgrades...

He doesn't have a tone of money do to a recent move to Florida so funding is tight but, I know him well enough to know that once he gets the car moving he probably wont be satisfied with the stock turbos for long. I know the turbos on that car are tiny compared even to the stock T25 that comes on the 2G but they are MHI turbos. I am assuming that the TD04 series is enough like the TD05 turbos in that someone can take the compressor of a slightly larger turbo and have the compressor cover machined to fit a larger wheel? I only looked around the net for a bit but really didn't find any services like this offered for the 3K cars like they do the the eclipses and EVO's. Really the only shop that I found offers a larger version of the TD04 with a price tag of almost $2.5K for the pair. Do you know of anyone/where that could possibly machine the compressor cover to fit perhaps a TD04-13T or 16G compressor wheel for a reasonable price? Or if it can be done on that series of turbo at all?

 

[delta448]

Justin feel free to correct any of this;

TD04 is tiny. You don't want a 16G sized compressor on that sized hotside, it would likely have surge issues. However, he could put a pair of rebuilt 16Gs into the DSM stock 14B 6cm TD05H hotside and make substantial gains, but the spool loss won't be unnoticeable either. Even a pair of 14Bs is a large setup on those cars. A pair of small 16Gs at a moderate boost level can produce over 600awhp in a 3/S.

Sorry my bad, according to this page Mitsubishi did manufacture a 16 size wheel for the TD04 series turbo it is a 16T not a 16G. So whether or not there is enough material in the factory TD04-9b compressor housing to fit one of the other factory TD04 compressor wheels (13C/G/T, 14T, 15G/T, or 16T) in it, or is the turbine shaft is the same on all TD04's and will the larger TD04 compressors wheels fit the 9B shaft? I suppose this is the way I should have asked it in the first place.

 

[pj91gsx]

What is this turbo, info i know: tdo6-8 on the compressor cover. It has a tdo6h turbine wheel, 7 blade compressor wheel, came with a t4 turbine housing w/ 40 or 50 mm internal WG, and came off a diesel.

 

[JusMX141]

Yeah but i already have a ssqv style bov(ebay) and if i just buy the real hks ssqv bov and recirculate it, it be better in the long run?

I don't like either of those valves, so I have no opinion here...sorry.

20g comp in e316 comp housing/tdo5h 7cm
18g comp in e316 comp housing/tdo6h 8cm?
20g comp in e316 comp housing/tdo6h 8cm?

18g comp in e316 comp housing/tdo5h 7cm = Not worth building unless you happen to score one cheap. For way less money you could have an Evo III 16G, and for about the same money you could have a TD05H 20G.

20g comp in e316 comp housing/tdo5h 7cm = The most popular 20G setup for our cars.

18g comp in e316 comp housing/tdo6h 8cm? = Too much turbine flow for that compressor unless you have a stroker or 10.5:1 compression.

20g comp in e316 comp housing/tdo6h 8cm? = Expensive to build, laggy, and only beneficial if you're trying to extract the most power from a 20G compressor....but for the same money you could have one of ten other turbos that make more airflow with just as much lag.

Justin, I would like to know the airflow numbers of this turbo please.

Search Google images for a T04E60 compressor map or click the link that Zack posted....and there you go.

I am assuming that the TD04 series is enough like the TD05 turbos in that someone can take the compressor of a slightly larger turbo and have the compressor cover machined to fit a larger wheel?

You can't use a TD05H compressor on a TD04 turbine. The hole in the wheel is too large.

Do you know of anyone/where that could possibly machine the compressor cover to fit perhaps a TD04-13T or 16G compressor wheel for a reasonable price? Or if it can be done on that series of turbo at all?

He could have the covers machined at somewhere like G-Pop Shop....if he's interested in going a 13G route, have him PM me. I have plenty of cores here...and they're not going to cost him anywhere near $2500. That's just retarded.

What is this turbo, info i know: tdo6-8 on the compressor cover. It has a tdo6h turbine wheel, 7 blade compressor wheel, came with a t4 turbine housing w/ 40 or 50 mm internal WG, and came off a diesel.

TD06H 24V.

Any turbo identification questions should be asked in the turbo I.D. thread, or you can PM me directly. As Brian said earlier:

Also, keep in mind we already have a "What turbo is this?" thread, so please use that for all your turbo ID questions - posting after searching, obviously

 

[97gst_spyder]

That's what I thought. I can get both the 18g and 20g for under 500 new. Using the 7cm housing.

 

[TurboAnything]

I just took apart a small 16g i bought the other day and it did not have a reverse thread on the turbine. Has anyone ever seen this? I have taken apart about 25 mitsu turbos and never seen this before.

The evo1 b16gs with number xxxx450 are right hand thread. So you got an earlier year. the evo1 i had, had loctite on it, and it looked original. You likely got an earlier model, or it was swaped out.
