It's a Flipside Customs manifold that has a Q45 throttle body flange on it. The plenum is bigger than the other versions because that tb is huge. If anyone is interested in a manifold from him he has a more conventional version that will use the Mustang tb as well. It's very similar in design, but will actually have a more finished look and seems like it will be very nice.
What do you guys think? Throttle body too big/small, plenum to big/small, runners too short/long, etc...

Yeah your gonna have to dyno it to see, but where are you looking for power and what kind of power will decide on plenum size and runners. Stick with the TB though, its definitely the right size.

The TB is what they call a 90mm, but it's actually tapered inside and only about 85mm or so. Popular on many other cars, just not the Miata, yet.
Looking for more power up top, so if I lose a bit down low it won't concern me. I can't wait to start using the TB and I do agree that it's the right size.
Sorry I didn't polish that up for you guys
. Mine has something a bit closer to velocity stacks inside it. Just didn't do a runner/headflange setup. Didn't have the ease of the injector in head setup. Wish I had that for simplicity though.


Jay: Not starting stuff, just found it fun to see a version very similar to mine. Has worked fine for me. Now go make some crazy power

Here's a picture of a test fit that I did earlier. Only thing that I ran into was the alternator bracket will get in the way so I will be having a new bracket fabricated to give me a little more space.
On a side note, anyone watch Pinks All Out at Pacific Raceways last night?

Put the factory intake manifold back on so I could go racing this weekend. Ended up getting a new personal best yesterday. Going back today to see if I can run faster or break the car trying.
You're into the safety requirements for 11.49 second car, have you met all of them?
