Filling Intake Ports When Going Peripheral
#15
Ok, I understand now. I thought you had the stock intake ports filled. I didn't realize you were referring to the rotor housing around the peripheral intake.
Looks like a good setup. You don't think there is any type of drawback from having the open ports? I suppose turbulence wouldn't be an issue.....hmm, interesting. It must be more reliable than having to worry about epoxy cracking and falling in to the housings

I'm not going to have a fancy manifold. I was going to just connect large diameter hose and use that. I could make block off plates for the intake ports on the front and rear housings since they are already tapped but the intermediate has no holes to use on my 12a. Did you tap the housing or were the holes already there? I much prefer the block off plate idea for reliability.

I'll take a couple of snaps of the port side (as opposed to the starboard side?) when I get home from work.
I'm sure the bolt holes were already there to take the manifold plate, as mazdaspeed7 points out.
Cheers, and good luck Heath.
PS. If you want a template of that intake manifold I can trace it up for you. Let me know. Will it fit the 12A?

I appreciate the offer but I don't think the template would work on a 12a. As it stands right now I think I will indeed make block off plates for the front and rear housings and fill in the intake ports on the intermediate since there is no way to secure a block off plate. I'm just going to add the Devcon in small amounts and allow it plenty of time to cure in between. I really don't want to lose an engine because of failing epoxy
Was there any kind of buildup you found in the stock intake ports when you broke down your engine? Thanks again for all your help!

A couple of things ...
The engine was very clean when I disassembled it. No build up around the intake ports.
When you apply the DevCon, are you thinking of putting a little on then letting it cure, then putting a little more in? I don't have any experience with that stuff but wouldn't it be better for it all to go in at once so that when it cures it forms a uniform, solid mass. My thinking would be that it may not bond together if the first blob has already dried.
You can block off the end ports but couldn't you drill and tap the middle ports, so that would be less messy and probably look more professional too? Even a pro shop would only charge you a minimal cost to do that.
