I was wondering if anybody makes after market 6 port intake lower manifolds. I am looking for a manifold to put on my engine but it will be going into an fb. I wont need any of the accessories...or at least I don't think. Can somebody help me and let me know what all the parts of the manifold do and what they connect to?

 

Ok I see what I need to take off. My only problem is I dont know what the parts are called. Can anybody post the pic of a manifold and tell me what the parts are called. I took off the thing in the middle of the manifold. I think it is called the Air Control and Check Valve Cover. I know I need to buy a plate for that. Now what about the parts that are on the outside of the manifold that deal with the 5/6th ports. Now if I get parts wrong please let me know.

 

You can find a link to the 2nd gen shop manuals in the FAQ. It covers the manifold in great detail.

As for an aftermarket manifold, RB and Mazdatrix have them but they are all designed for carb applications.
