Building Custom Intake Manifold.

Yeah, I think you need a plenum...
There's some weird resonances that might affect performance; Mazda went through a lot of R&D to minimize it's disruptions and maximize it's effects to performance.
Get a dyno run on that thing!
It looks promising!

Yes, why? I would have used those IDA style throttle bodies for sure.

Looking good dude
Could you get some pics on how the intake runners join onto the plate that bolts upto the engine...
Ive been wanting to make my own intake for a while now, and i carnt seem to find any pics on the join to the intake flange...
How did u bend the pipe, what did u get your flange made out of?
Thanks
Peter

The flanges is made of a 8mm steel plate. I`ll take some more pics of how the pipes attach to the flanges later this week..
I choose to use the stock tb because I wanted to be able to only use the primary intake ports at part throttle, giving better idle and midrange power. If I had used ida styled tb, It would have used both the pri. and sec. intake ports at any throttle. There is a good thread about intake runner length at the "rx7club.com" where you can find the formulas for estimating the runner length.
