not stock turbo on my a/t?

[staticbrainwash]

alright, as per my knowledge on dsm's, i thought that 1g a/t's came with a 13g turbo.

i did some research looking for some turbo seals for it, but i noticed that my comp housing says TD05H. which i don't think was used on the 13g.

can anyone help solve my mystery? i'd be happy to learn i've got a 14b or even a 16g.

 

[keymaster]

ALL 1g's come with 14b's.

 

[staticbrainwash]

all? i could have sworn the auto's came with a smaller faster spooling turbo.

 

[BlackbirdOfPrey]

Wrong, A/t came with a 13g. They also have smaller injectors I believe 390cc.

 

[BiGGinZ]

The auto's come with the 13b, I know at least some did. I am pretty sure that the TD05H housing was on the 14b and 16g. You will probably have to look in the turbo at the wheel or find some more numbers to tell the difference though.

i guess my real question is. . .

weather or not it's a 13g, could i get a 14b, and leave the bcs on it to keep boost low?

or would i still need to do a fuel upgrade from at to mt. (ecu, injectors, fpr)?

i've got oil burning somewhere and im thinking it's my turbo seals. thats why im curious

 

[psychlow]

Yes, you can do it if you bypass the BCS and run the boost source straight to the wastegate. If you keep the BCS, run a logger to make sure you're not knocking.

 

[staticbrainwash]

wouldn't leaving the bcs on keep boost at the same level though no matter the turbo?

so why would i need a logger if boost isn't being pushed up at all?

Because a 14b or 16g is going to flow more air at the same boost level, which could potentially overrun your stock injectors.

I believe the 13g is a TD04 housing, but I could be mistaken.

Correct Psi doesn't mean much, you have to look at airflow. 13psi on a 13g is way different than 13psi on a 16g.

Just so you know what your looking at. Here is an automatic's 13g/TD04 next to a B16g/TD05H. Also the TD05H housing can be found on the following MHI turbos 14b, small 16g, 16g, Big 16g, Evo3 16g, 18g and some 20g's

Here is the same 13g next to a PTE gt32E 50 trim.

[staticbrainwash]

wow, im not necessarily new to this game, just not a whole lot of exp. with turbos.

that 50 trim is f-ing JIGUNDEROUS in comparrison. . .

i dunno, ill have to pop everything open and take a look and the compressor wheel, i heard that the 13g were twin finned, where the 14b was single.

if not, i've got a TDO5H housing and a 13g wheel. . . which doesn't seem too likley.

if i am running a 14b and i ovbiously havn't made any fuel mods, is this dangerous?

everything in the car right now is pretty much stock.

 

[fwdturbobov1996]

take the intake pipe off.. if the fins are the same length.. 14b.. uneven length 16g.

 

[TURFNNSURF]

Static,
If you want to run the 14b on your car for the time being, I would suggest doing at least the fuel pump rewire mod from the VFAQ section. It may help you out a little. Better yet, a set of used 450cc injectors can be gotten on Ebay for cheap and they will give you a safety margin also. As a matter of fact I have a set of 450's from a 99 GST that just upgraded to my old 650's, I think my buddy is looking to sell them. PM me we can talk about it.

 

[staticbrainwash]

i thought though that in order to use the 450's i'd have to get a manual ecu and manual FPR.

if they'll work otherwise, thats sweet.

You should be able to put that turbo on there without doing any fuel system upgrades as long as you keep the stock boost control solenoid hooked up. As long as you dont run more boost pressure than stock you wont increase actual flow rate. Yes, those larger turbos are capable of higher flow rates but with a control solenoid they wont ever flow that much since flow rate is a function of resistance of air flowing into the cylinders and the pressure applied to the air being forced in. Since pressure will be a constant due to the boost control solenoid and wastegate, and resistance thru the motor will be the same since you will not be changing heads/cams/ext..

The only way to increase the actual mass flow of air entering the engine under these conditions would be higher boost pressure or cams/heads/ext.

A manual ECU would be helpful, but it's not needed right away. However like Pat just mentioned if you leave the BCS in place you should be fine on the 14b at about 11psi. But I would still rewire the fuel pump...

 

[staticbrainwash]

thank you so much guys. that was my automotive lesson for the week.

now i need to find myself a 14b and get ready for a swap.

would it be a better idea to look at getting a new turbo if mine's blowing a little oil, or just try to replace the seals?

 

[doug]

My guess is that you already have a 14B since it says TD05H on the comp housing. Just check the fins-- as was mentioned, G turbos have the "twin" fins, B turbos have evenly-spaced ones.

As far as replacing the seals, it's your choice. Personally, I'd replace the whole thing if you can afford it. Plus, that way you'd KNOW what it is.

Anybody read those before they post.

Look just for clarification the 1g a/t's came with a TD05H 13G, a smaller offset outlet to the exhaust manifold to match the small inlet to the turbo, 390cc injectors, and an ecu with different mapping. If you take the manifold off and the outlet is offset to oneside and it matches the turbo, you have a 13G, it's that simple to find out.

 

[staticbrainwash]

thank you mavisky.

i knew about the 1g at's but the compressor housing threw me off real bad.

sorry if this was discussed somewhere else and i didn't get a zero in on it with the search.

now. . . i've looked everywhere, sbr's website, dsmparts, machV, and i can't find turbo seals. . . are they really this hard to find?

cuz i think if im going to go to a 14b im gonna do it right and get all the right fuel mods for it.

and i definately don't have the money for that right now.

 

[mavisky]

Get the seals from mitsu.

For the 14b, all you need is a 14b (duh), a 1g 5-speed manifold (or better), the stock injectors (pretty easy to come across), and a 1g 5 speed ecu.

All together you're looking at maybe $300 total

$100 14b
$50 1g manifold (and that's a bit pricy for one)
$50 450cc injectors
$100 5 speed ecu

The manifold, injectors, and ecu are even priced a bit on the high side, the turbo is about right on.

 

[doug]

the 1g a/t's came with a TD05H 13G

You sure about that? The 1000 AAQ list says this:
"14B turbos are stock turbos on first-generation manual transmission cars. 13G turbos are smaller, and are stock turbos on first-generation automatic transmission cars. Both are made by Mitsubishi - the full numbers are TD05H-14B-6CM2 and TD04-13G-5CM2, respectively."

 

[mavisky]

Cought me in a slip up, yes the 13g is a tdo4. Oops.

 

[staticbrainwash]

wow, so now im really confused. . . i guess i have a 14 on my at then. . . and i know i have 390 injectors cuz i had to replace em. (all orange top when i pulled them off which im pretty sure is the 390)

so i guess my question now is. . . anyone got a decent 1g mt setup the need to part ways with?
