If you've rebuilt your twins could you please explain how to seperate the cast iron manifold from the twin turbo assembly?

It looks like maybe either some "C" or "E" clips? The nuts are obvious and have been soaking in PB blaster.

I'm not sure if I will port the wastegate with just a dremel but my intension is to heat coat the manifold. I also need to seperate the dealybop from the exhaust manifold as well.

 

im not totally sure on what your saying... but to remove the turbos you loosen the oil feed line, and the water lines (2 of them) and then you unbolt the studs. (i think there is 8 or 9 i cant remember) all the bolts are a 14MM but one, which is a 12MM. and I would port the waste gate while you have the turbos out. It took me about 10 mins to port mine. and then after you take the turbos off take the heat sheld off the Exhaust manifold and there are 4 14MM bolts. and undue those and everything is off.

 

Dont forget to unbolt the oil return line.

 

To actually seperate each Turbo from the manifold you need to take off the 6 bolts/3 retainers that secure the components together. .

....BUT make sure you place index/alignment marks on the Turbo and Manifold before you take them apart.

If you're referring to compressor housing (snail)seperation from the bearing housing, you need to take off the large snap-ring that holds them together.

 

I want to seperate the snails from the attached cast iron housing they are both attached to jointly. I call it a turbo manifold because there is allready an exhaust manifold that the entire turbo assemble attaches to. I'm not sure if that's what you're calling a bearing housing.

Anyhow, the actuators with the rods are connected with some kind of clips to the manifold.

So forgetting the exhaust manifold, I want to remove the snails to heat coat the turbo manifold that is "part" of the entire turbo assembly. If I can port it with my dremel then cool, otherwise heat coating is the main objective.

The only problem I see other then the retainer clips is the scripe part. If I heat coat the manifold then i'm not sure if the marking will still be visible.

Someone on here had it done by bi-state customs but I can't remember her user name to link the picture.



The thread that I got the pic from above.

 

Just unscrew the 6-10mm bolts w/retainer clips and they'll come off. You might need to tap the compressor housing with a rubber mallet a bit to break them loose from the manifold. Don't forget to place alignment marks.

When the Turbo comes off the Manifold, the Turbine Wheel will be exposed on the other end of the Bearing Housing.

The Compressor housing (snail) will be attached to the Bearing Housing via a large Snap-Ring. When the Compressor Housing is taken off the Bearing Housing, the Compressor Wheel will be exposed and will remain attached to the Bearing Housing.

Then you have an empty Compressor Housing (snail) and a Bearing Housing with wheels at each end.

 

If you port the wastegate with a dremel it is going to take you about 4 years. Take it to a machine shop. It shouldn't cost you too much.

 

GORACER,

I suggest you get a Mazda Service manual and learn the real lingo for our car parts. It also shows how to do many things.

 

^ You mean the service manual that is both on my coffe table and on my ofiice desk the does not have a chapter on lingo? Hmm, yeah it's amazing ....not. None of the reply's refer to the lingo turbo assembly, maybe it's in my missing chapter.

ok, I feel better now.
