I'm looking for an intake adapter, specifically to use a 13B intake on my 12A. This is for fuel injection, and maybe later down the line turbo possibilities.

I remember someone making them, and I remember talk of Billy making them, but what's the defiining word on them.

 

I know there is one made for the reverse of what you want, have not heard of one made for your application though. I wonder if you could flip one of those around, fill the bolt holes and drill new ones?

 

hmmm, well we'll see. This is just a project idea. I have some S4 parts laying around that I thought I might be able to fanagle something cool.

 

Mazda comp did sell a blank intake flange. You could mod it to fit your app.
