13G on my JDM engine...let's talk...verse T25

[Chris Doss]

Hey all I have a 13G on my JDM engine, if I remember right then this means it came out of a galant. At any rate my T25 isn't looking so good and I wanted to know what the difference was between these two turbos. I've done som research and don't have a definitive answer. right now I'm thinking to just leave the 13G on the JDM motor and not mess with swapping the T25 in there (has shaft play, lots, not sure if it is still good and don't want to have to go back in more than needed later, my time is valuable, very). Once everything seems to me working well I'll move forward with the T28 I have but...

What's up with these two turbos? T25-13G what's better....

thanks all

They each spool about the same. The 13g flows 360 cfm, while the t25 flows 325 cfm.

i'm sure the 13g will take more abuse and otherwise outlast a t-25.
mhi turbo's are built to last and come with 360* thrust bearings. wheras yoru t-25 only has a 270* thrust.
both weak turbo's,
but i'd stick with the 13g.

btw,
your jdm motor having a 13g only means that your jdm motor was an automatic.
but all jdm 6 bolt 4g63's were galant motors.
they didn't have eclipses in japan.

enjoy the tdo4 glory.

The t-25 will most likely spool quicker.

The best thing about having the 13G is that upgrading to a 16G is even easier than upgrading from a T25

Thats not true at all.
The 13g is a tdo4 turbo.
That means you would need to change all the oil and coolant lines, the water pipe and the exhaust manifold to go to the tdo5 16g.
To go from a t25 to a 16g requires less changing of parts.

But I would keep a 13g before changing to a t25.
Its in such a small housing it spools instantly.

Alright, the 13g can bolt up to the stock 2g manifold. It uses all the same oil lines, and only needs the 14b coolant lines to install a 16g. It will use the same J-pipe. I don't see how it would require less parts to go from a t25 to 16g.

You have no idea what you are talking about.
When you have actualy done a few of these then get back to me and let me know how using the stock oil lines from the 13g worked out for you on a 16g swap.
Oh and you are not using a 2g manifold on a 13g either.

You need to get your facts straight before you go off and tell me I have no idea what i'm talking about.

As for the oil lines, a 16g swap...

So from what i read i'm assuming a turbo with a tdoh5 housing will use the same lines interchangable.

So a 13g to a 16g swap would be the same as a 13g to a 14b swap. All that is needed in a 13g to a 14b swap is the water lines, from what i've read. I could dig up the 14b lines I have in my garage and compare but i'm lazy at the moment.

So to go from a 13g to a 16g all that would be needed are the coolant lines, I'm assuming.


And as for your comment to me that in fact I'm not using a 2g manifold with my 13g, I guess your right...

As your can see the larger runners, the machined bolt surfaces, the more webbing, and the heat shield mount reinforcement that this is infact a 2g manifold.

The other mani was the stock 1g a/t that came off a long time ago.

Still have the tdo4 1g stocker, but that is soon to change.

here is my ported 13g bolted onto my ported 2g manifold.

I dont need to read any of that.
I have done these swaps and the oil return line on the smaller tdo4 housing is longer. It is longer because the turbo is smaller and doesnt sit as low. Measure them and then tell me what you think. Try taking the bonjo bolt that goes into a tdo5 and try putting it into a tdo4 housing. It wont fit, period.
Try it for yourself and then tell me what you think.


Here try reading this. http://www.dsmtuners.com/forums/showthread.php?t=250074&highlight=13g Or just type in 13g in a search and read. There are a few who have actual done it and not just read misinformation and then went around repeating it. Becausre of people who say it should or I believe... That means they havent done it and are just guessing.
So again I will say you dont know what you are talking about.
But there is nothing wrong with that.
There is something wrong with continuing the spue of missinformation though.
Try learning first hand and stop just believing everything you read.
You will be more knoledgable in the long run.
You dont have to take my words as the truth just try and do this swap then get back to me.

Nice numbers with the evo3 Tom, real nice.
