Ok so I used a Racing Beat Flange and had a manifold fabricated for my 13b for the FD. Here is the Flange.

So what gasket should I use now?

Engine-to-Header Gasket
84-92 13B 6-Port Engine


Engine-to-Header Gasket
87-91 TURBO II


Or 2 of these from MazdaTrix


Thanks guys

Id go with number 2. There pricey though.

The gasket costs more than the RB SS flange wtf lol?

for turbo applications the stainless steel gasket in #2 is recommended.
I have used the "asbestos" gaskets #1 before and have never hand an issue with them. despite blowing out my manifold-turbo gasket regularly.
most of my motors come with gasket #3. after a good clean up i reuse these the most. just watch out for cracks.

PS that flange is universal for all 13b. it has small ports for NA and your expected to drill them out for turbo applications. I used a die grinder

Well just got off the phone with Racing Beat and they actually recommended the factory Mazda gasket.

#3 is the gasket for some later s5 and s6 engines, #2 is the gasket for most early s5 and s4 turbos and #1 is a oem replacement gasket. i personally use #3 due to the fact that they are seperate and allow you to get a better clamping force on them. ever see the one piece gasket when you take it off? its all crumpled and bunch up in the center.
