Ats manifold installation

HELP! Ats manifold installation

Ok guys I just ordered an ATS 2 peice manifold and a phat shaft 62 turbo. One question I have is what size do I need to drill the hole and what size tap do I need for the pyrometer probe? ( My probe was installed by a diesel mechanic when I got the truck) And are there any tricks or tips you guys can give me for installing everything else? any help appreciated. By the way my guages are isspro, and if I understand correctly the ats manifold is supposed to come pre tapped? Maybe I overlooked it, since I just glanced over it yesterday. Any way Help is appreciated because I don't want to mess this manifold up! But I'll look at it again and see If I can find the hole.



Thanks

Chad

For the tap-



If using a fitting that is 1/8" NPT, then you need a 5/16" bit. The 1/4"NPT takes a 7/16" bit.



For easier assembly, put one section in the freezer, the other in an oven, or in front of an gas fired heater. Make sure to use plenty of anti-seize on the joints.



Can use the OEM manifold as a guide. Make sure that both halves are sitting flat, and not to have one piece tipped.

On ATS's website it states that all manifolds come pre tapped for pyrometer probe.

Unless they started doing it halfway recently, mine wasn't.

Mr Moeller,



ATS states that the manifold comes pre drilled on their website. I don't know for sure , just trying to relay the info that I see.

As for assembling the manifold, wait until you remove the old one, and use that as a template. Assemble the new 2-piece manifold by hand (don't worry about getting it pressed together all the way - just enough so it won't come apart), and put it port-to-port with the stock manifold. Bolt one half of the new manifold to the old one, using bolts that fit through the mounting holes with little to no slop (I think I used 1/2" bolts). Use at least two bolts in diagonally-opposite holes (ie. bottom hole of #4, top hole of #6).



Now, invert the assembly, holding it by the bolted piece, and tap it repeatedly on the ground (preferably concrete). Pretend it's a mini pile driver. Don't slam it, but do let it fall naturally from 6-8" or so. Do this until all the mounting holes are perfectly aligned. Bolt the other half of the new manifold to the old one, to make sure all the flanges are in the same plane. Now unbolt the new manifold from the old one, and you're guaranteed to have it perfectly aligned for installation.



I did my first two-piece manifold with the freezer/oven, pounding it together with a hammer and a block of wood. Way too much work. When I put my 3-piece manifold on (same process as the two piece, only it's gotta be done twice), I used the above method, and it took all of 2 minutes. MUUUUUCH easier

Ok Thanks alot guys, this info really helped. I bought the manifold off ebay from a diesel shop. When I got the manifold it came in an ats box, and like you all said the ats website states the manifolds come pre dilled, tapped and assembled. But I have the manifold, and it is not pre drilled or assembled, but oh well this information helped alot any way and again thanks.

I put a 3pcs on my 12v about 2 weeks ago. It did'nt have a hole for the egt probe so I had to put one in. I'm veary pleased with it. It lowered my egt's about 150deg. I also seen A difference in the porformance. Does anyone agree?

Right... there is a boss cast into the manifold, where an EGT probe can be placed. It's a little round cylinder that looks like a short stack of nickels. Here's a picture of my old manifold:

You won't have a hole there, but it should be dimpled. You can just drill/tap this spot, but IMO you'll get more accurate readings if you tap the 4-5-6 collector, just above the turbo flange (because the back cylinders tend to run a little hotter). See here:



#ad




Drill about an inch above the flange, and make sure the hole is centered in the port.



I'd also suggest drilling/tapping the provided location (first pic) as well, and fitting an 1/8" pipe plug in there. This way, down the road, if you ever wanted to add either a second EGT probe, or maybe a drive pressure gauge, you'd be all set.

I don't really agree with that,even using anti-sieze on that plug you may not be able to remove it by the time you need it

Wasn't a problem for me... I ran mine like that for about 6 months before I got my TST box and put a thermocouple in there. It twisted out without too much effort. If it's a concern, use a brass pipe plug.

ATS 3-piece manifold assembly

Wow! this is great and timely info. I will have to assemble a 3-piece this next week. Tks for the info.

Glad it helps. For the three-piece, bolt the center section on, and pound each outer section in place. I can't take credit for this - I got the idea from another post on here I was amazed at how easy it was.
