I want to remove my exhaust port sleeves
I am trying to install my RB header. I have the manifold off.Now I want to remove the sleeves that are in the ports. I cant't get them to budge. what do I need to do?
help quick. the car has to be a the exhaust shop in the morning so they can finish the rest of the pipe after the header.
I gues I should cearafy... I don't want to remove the sleeves i want to remove the steel "exhaust splitter" part in the sleeves. how do i do this?
thanks

Well obviously he wants to remove them for exhaust flow/breathability... The turbo II cars have em the N/A's dont... I removed mine when i did my rebuild with a air chisel and some ingenuity.... but... you have to grind and grind and they take forever to get out.... i dont know how good an idea it would be to do it with the engine assembled...

Is there any real gains from doing this? My engine is getting rebuilt right now and I noticed them and was wondering about it. Performance help or just make it tons louder?

they all do!.
turbo= no diffuser
N/A= with 2 diffusers per sleeve.
I also wants to know how to remove those sleeves to help out one of the forum members for his project.

I'm doing this for the N/A that im building.
It takes about 20 mins.
You want some sort of sleeve in there, all the N/A came with a blockage in the middle of the port to quiet noise and increase low rpm torque.
The Turbo II's didn't have the blockage instead had a clean diffusers w/ nothing in the middle.
They can be taken out by drilling the pin out in the above diagram. I'm freakin' drunk right now, so post more if you have questions, but I know all there is to know about this. If you do a search I asked a question like this, and Mazdatrix themselves answered with Dyno Proof!!
Enjoy

I just left them in. I needed to get the hting done. I had a **** time getting the whole thing up. since the replacment cat was welded on, I had to leave the old exhast on the car. fitting the per-silecer on there with the othe pipe hugging it was not easy at all. then when I was leaving to drop off the car at the shop, I heard a grinding sound. I was dragging th old pipe. so I had to wire the thing up whith the car square on the ground, in the dark. I didn't want to start the car again becaus it was 2:00 am and every sound bounces around in my neborhood. then I drove the car, wiht nothing behinde the pre-silencer, 37min to the exhaust shop in the middle of the city that I live outside of. I had to hold my ears the whole way it was so loud. once I got in town I had to roll up the windows because the sound bouncing off of the buildings was louder than in the car. anyway I ma glad it is over but I am worried. i don't like letting other people work on my car. imagine taking your daughter into surgery. I have to trust this guy until I see the finished product.
that, and I hope i designed the system correctly. ever since I heard my first botched exhaust for the rotary, I have been worried until I heard it. I have done a few and had no problems. each a little different than the others. No bad ones yet. but I love this car the most of all the others I ahve had. she is my baby. I have never been in a car with this many origonal mile on the motor pull so hard. 151,000 and still quick.
anywayenough mushy stuff I have to go and clean up my mess, then me, then I go to bed.
thanks again
