I am wanting to port my exhaust ports but thoes dam difusers are there.

now I have heard how hard they are cause its SS, but i would like to know if anybody has ever got them out?

what did you use?
how long did it take?

also if i can get the difusers out can i than use the mazdatrix exhaust port templates?

thanks

 

anybody?

sorry im in a hurry to see if i should order the exhaust template or not

thanks for any help

 

The best course of action is to drill out the pins holding in the stock ones, and use a set of turbo sleeves without the diffuser (they get pinned back into place). Then you have no diffuser, and the exhaust port is basically that of a turbo II.

I keep rotorhousings from turbo motors that arent useable in rebuilds for this purpose. I can sell you a set (still in the housings, you have to remove them, and since you have to do your originals, there is no point in me fooling with these when you will have everything necessary to do them) for $40 plus shipping.

 

Kevin,
We've found that drilling them out is time-consuming and risks damage to the housing. A good slap hammer fitted with the porperly sized body screw will have the pins out in seconds. Just be sure not to snap the screw in the pin, or you're really out of luck.

 

any other ways of just removing the top part of it and leaving in the pins? i would like to do this in the next few days.


like is there any strong bits that i can drill or saw blades?

 

blowtorch

 

In my humble opinion, taking the pins out is the hardest part of the job. With a hammer as suggested, they pop right out.

As for removing the diffuser, torch it all the way. Just don't wildly warp the sleeves.

 

On a side note evenly heat the area with the torch to prevent warpage

 

so there is a way of just removing the top part of the difuser? like will the pins still be there? i cant really tell how its in there by just looking at it.

thanks

 

If you use a dremel with some bits that are meant to cut through hardened steel, then you can cut the difuser down so that the hole is round. Yes, the metal insert will still be pinned to the rotor housing. This will help keep the heat away from the aluminum a bit more. It really wouldn't be hard to pull the pins and relpace the steel inserts with a set from a turbo motor. That would be a lot easier then cutting out that hard *** steel.

 

ya i just dont know where i can get 2 turbo difuser localy. im already waiting on a bunch of other ****. i cant really wait on something els.

hummmmmmm
and also can you see the pins clearly? cause i cant recall seeing them. and u just have to pound them out with a hammer eh.

 

the pins are on each side of the rotorhousing, the sides that can only be seen while the engine is apart.

 

The pin is in the area where I circled in red. Should be one on each side

 

kool thanks

so if they are on each side? how are you asposed to pound it out? wont the other pin on the other side go the other way?? hahah

ill have to go look again tomaro the engin is apart and at a friends house

 

There are two seperate pins. Pull the pin towards you, then turn the housing around and pull that pin toward you. Then you can pull the steel insert out.
