So I went to my local Mazda today to try and find the gasket that goes inbetween the two turbo's. Tried to find it for a while and was told that Mazda doesn't make it.

What do you guys do when you seperate the turbo's from the middle housing? Doesn't look like the gasket is reusable since its just a metal one.

Is there an aftermarket one out there?

Thanks for you help in advance guys!

 

I'd give Pineapple Racing a call. You can purchase the gaskets from them (they have graphite ones, and the OEM steel ones, I'd go with steel) AND you can also get some really nice copper-clad locking nuts at the same time.

IIRC when I got mine I also got all the studs from Mazda (Ray Crowe at Malloy Mazda) just to be on the safe side.

All told you're going to end up spending about $250 if you replace all the gaskets and studs at once (which I would suggest being prepared to do in case something breaks during the removal).

 

buy new nuts & studs, just clean up the metal gsk & re use it. i did that with mine no problem.

 

^I think that depends a lot on the condition of the gasket, and what (if anything) else he is changing.

When the original gasket is installed it's "crushed" in to fill all the gaps and prevent leaking, therefore providing a good seal. If the OP is changing anything out (turbo's for example) then it may be best to get new gaskets as well so they can seal fresh to the new variations...

 

call Ray Crowe at Malloy Mazda. If it's USDM and he can't get it, it's simply not available.

 

i reused mine...was i not supposed to? lol

 

If it's holding fine then you should be good. When I installed my BNR's I kept the same gaskets in. Granted, later on down the line I had the small stud on the bottom of the secondary turbo walk out, creating a HUGE exhaust leak and shredding that gasket (which led me to replacing them both, and all the studs).

I'm not saying that reusing the old gasket was what caused this... but if you're *just* changing the gasket then there is probably a reason. Personally I'd rather be safe then sorry in a case like that..

 

I had them apart to port the waste gate. Everything came off fine, no problems with studs and what not. Just trying to put them back together and the old gasket has been crushed as previously stated and I just want to make sure I won't have to take these out of the car again because of a leak.

I checked Pineaple Racing and all I see is the Turbo to downpipe or Turbo to Manifold gaskets. Am I blind and not seeing the correct one?

 

Mazda does not sell that gasket as a separate item because they are part of the turbocharger assembly.

Pineapple might be able to make a graphite version but I don't think they have yet. The graphite makes a great seal but I'm not sure that it can handle the pressure in that area. Rob told me that the graphite gaskets are more recommended for low backpressure such as further down the exhaust (after the turbos).

As for your situation, if they are the same two housing halves, just put it back together. They will compress the gasket almost identical as it was before. This has been done many times with few problems. If you feel really worried, you can take a thin knife and spread the layers of the gasket slightly. This will restore some thickness and improve the seal.

This is the thick shiny diamond-shaped gasket between the rotor housings and exhaust manifold ('brick') yes?

They're usually reusable depending on mileage/condition. Look for evidence of exhaust leaks (black marks extending towards the edge of the gasket).

Also, for anyone who doesnt already have it, Ray's number is 888 533 3400

Edit: I realize now that you were talking about the gasket in between the two turbocharger exhaust housings. My second question still stands though (about the evidence of blowby).

 

Oh, wait... you were actually talking about disassembling the turbos themselves from the get-go, weren't you? If so then I misunderstood what you were asking (I thought you were talking about the two gaskets which go between the turbo's and the exhaust manifold). Please disregard my previous statements about gaskets and such, as I'm not talking about actually taking the turbo's apart and I have no experience with that, whatsoever.

 

The gasket wasn't leaking before and still looks descent but I just didn't want to chance it and would rather change it to be on the safe side and not have to take these back out. Then i'd be back to square one!

Now that it seems to be hard to find I might just reuse it. I'll try Ray first.

 

Talked to Ray today and was told that this gasket doesn't exist at Mazda and that maybe a turbo rebuild shop could help me.

So I will try to reuse the old one.

Thanks for the help boys!

 

Try giving Bryan (BNR's) a call. He should be able to either, A) sell you the gasket, or B) tell you where to buy it.

If anyone finds a source please post it. To my knowledge it has never existed.

 

Clean it, coat it with a little c5a and reassemble

Checked already. They don't have it!

 

A very quick response from Bryan at BNRTurbos.com.

I guess you guys have been doing the right thing all along

Still surprised no one makes these though!
