FA20Club Cold air intake is what your looking for. Go to the selling section.

I have seen them but not for sale

I've never seen one and all the old suby motors all have round runners. What are you trying to accomplish?

But maybe there is a manifold that has the mounting holes equal or at least similar to the BRZ that one can modify with an adapter for the round runners.

I'm in the starting pits of building my own SC-BRZ

I don't think there's anything wrong with the factory intake manifold though. You wouldn't want aluminum compared to the plastic one, it holds heat more. In fact, did you know the newer WRX manifolds flow better than the current gen STI manifolds?

Plastic/composite intake manifolds are better than metal, assuming they aren't leaking. You don't have the imperfections of metal casting (rough surfaces etc) and it weighs less. The only issue for a custom project is that yes, you can't cut it up and weld to it.

plus I'm pretty sure the runs at 620whp were with the stock plastic intake if you're worried about blowing it up.

Since JDL blew up their intake manifold, I believe they are designing one. I'm sure it will be pricey though.

I won't run super high boost or an insanely amount of torque/HP so the difference in heat shouldn't be an issue.

Why do you need to weld to it?

As for heat, even a stock engine without boost will heat soak the manifold enough to make a noticeable change in performance.

Unless you're running enough boost to burst the stock one, or are running really aggressive cams that require a totally different runner length and plenum volume you shouldn't have to touch the manifold.

Im not going into detail but to avoid further speculation and the spread of false information I picked up solid gains on my sheet metal manifold. its well worth it for a boosted application over 500.
