FA24 old gen brz intake manifold vs stock

[PollyPoger1]

Hi all, I have a 2017 Subaru wrx, and I’m currently looking at doing an fa24 swap since I found some good resources on it, and since it reuses the stock wiring harness for the fa20 and the only fabrication required is to modify the crank position sensor holder slightly, it seems like quite a feasible swap. Currently IBR sells a fa24 swap kit, although it uses an fa20 intake manifold, such as the red brz one. I like the red brz intake manifold since it relocates the throttle body to the front which is better for a fmic. My question is, will the red brz intake manifold flow better then a stock fa24 one, and would something like the fa24D intake manifold off of the new ‘21 brz’s fit on the turbo fa24 to shorten the intake piping for a fmic?

Any news on this? I'm thinking of swapping a BRZ manifold to my 2023 WRX.
