Does anybody have any specs on the T04B that ATS used in their 6.2 kits?

I found that it has a .60 A/R compressor housing and a .96 A/R turbine housing. And it was made by AiResearch, which is Garrett.

By the way the compressor wheel is a 55mm/70mm.
And the turbine wheel is a 64mm/74mm.
The compressor inlet is 3" i.d.
And the compressor outlet is 1.75" i.d.

They call the turbine wheel a "P" Trim wheel btw.
on the 82-87 style setup, it's a basic TO4B Turbo in an On-Center T4 Turbine housing 4-bolt downpipe outlet, primarily a .96 a/r, but also came with a .81 a/r turbine.
Good to know the compressor wheel specifications... Haven't measured one.

It's an old Garrett AiResearch T04B. What are your thoughts on the turbine A/R? Also what does "P" trim mean?

Does anyone have an intake plenum for an old ATS turbo setup? Also is there someone out there that has any ATS literature, like instruction sheets or manuals?

There are two ATS Setup's.
What version do you have? You'll need to post pictures of what you have and I can ID it for you.
P trim is just a name for the size wheel, instead of calling it a certain sized mm inducer/exducer size wheel.
Turbine housing size thoughts? .96 a/r is too large for a vehicle with higher gears and overdrive transmission. It's ideal for a truck that's got no overdrive, with 4.10 gears in the back (engine is reved up).

I do have a 4.10 gear, but I'm running a 700R4 with 35" tall tires. I'm only making around 1800 rpm's at 65 mph. Do you think that it would be possible to get a .81 A/R turbine housing. I'm already having trouble finding a plenum that is not chopped up.
I almost forgot what truck that I'm working with. This truck will have 4.56 gears with the same transmission and tires.

Is that your setup up top?
Do you have the other broken part off the upper plenum? I'd suggest welding/rebuilding it.
It's a unique piece.
Won't find one of those used I suspect.
This is the 82-87 truck, 82-91 suburban & blazer style setup. ATS did make a 1988-1993 6.2 setup that fit the GMT400 style trucks.
I don't know whether this will fit in your truck or not.
I'd suggest removing your passenger's side exhaust manifold and installing just the manifold on your engine and studying what will clear the frame etc. It looks like it might because of how the crossover pipe is made (comes in through the back instead of the front like the Banks).
Do this before trying to figure out how to get an upper plenum, You may find out this just won't fit your Suburban being a 1992 GMT400.
I'd try the .96 turbine. The .81's are easily attainable as a generic On-Center T4 4-bolt downpipe for a P-Trim Wheel.
If it's too laggy and too little boost is when you'd step up to the .81. The .81 gives you the ability to just lean on the throttle while in overdrive with a locked converter and actually make more boost. The .96 will just stay almost constant, until the transmission shifts down, then you'll get more boost.
Here is what it's supposed to look like setup.

That's all of the plenum that I have. I have a CTS plenum that's basically the same. But I had rather not use it if I don't have to. I am working on a 1984 Chevy 4x4 pickup with this setup.

That would have been good to know from the beginning, instead of trying to figure you were installing this in your 1992 Suburban...
You can use the plenum you have, just get you a 3" 90 fitting to attach to the turbo and some 3" exhaust tubing and make an air intake with a filter on the end of it. The main part missing off your plenum is the clean air side into the turbo.

Sorry about the confusion, sometimes I forget which truck I'm talking about. Here's a picture of the CTS stuff that I have. I really want to use a plenum where I can use the factory breather if possible. I have a 4" cold air intake straight from the front to the breather now, so I want to keep that. That CTS manifold is for a T3 turbo where as the ATS manifold is for T4 turbos.

Thanks for sharing the PIC of the CTS setup.
I thought I'd seen them all, and then there was this setup.
Looks like an ATS knockoff in design.
I liked the ATS setup for the 80's, it had good response because of how the manifold was constructed and all. But maybe a lot of that was the exhaust housing I had with my setup, which I sadly sold years ago (regretfully).
I'll keep an eye for one of those plenums from an ATS though.
you could certainly build you one from scratch though. Have you seen the BAE 6.2 Setup? It has a plenum adapter made of generic stuff, not a casting like the ATS was. I can find a pic of that and upload it to give you some building ideas.

The CTS manifold is basically the same without the exhaust part and with a T3 flange. The CTS plenum seems to be nicer to me, as it doesn't have provisions for the EGR cast into it like the ATS one does. The BAE is a new one for me, never seen that before. The manifold looks like a Banks design.
You mentioned an exhaust housing, what kind of exhaust housing were you talking about. I would really like to have an ATS plenum just to have a complete set, so if you could find one I would greatly appreciate it.
By the way, CTS is Canada Turbo Systems.

I found some sources for different A/R turbine housings, but there all seem very pricey. Do you know of a source that might have reasonable prices? Something tells me that I might need a .81 A/R housing instead of the .96 A/R housing that I have.

You bought the kit I almost bought! Was going to put it on my K5 but decided to wait on some funds.
I do have the ATS on my 83 and somewhere I obtained copies of the original ATS literature. I'll see if I can put my hands on it and let you know.

Sub,
I really appreciate you looking for the literature. One of the things that I need to figure out is where to put the hole in the valve cover for the turbo drain.
Does you 83' have a 700R4 and what gear ratio is it. I'm a little concerned that the A/R of my turbine housing might be a little large for my setup.
On second thought, I can't keep it straight which truck that I'm working on, I just plugged in the numbers at http://www.grimmjeeper.com/gears.html to see where I'm at, and it might be just right. The calculator shows 1992 rpm at 65 mph, so maybe my A/R will be just fine.
What kind of mileage does your 83' get? Do you have any pictures?
