Yep, those are just ported runner that the plastic stock manifold connects up to, the the RBC is a complete cast aluminum piece and is most definitely better than that stock piece with the ported runners.

I doubt there's a lot to be gained here excepted, of course, if the ports in the head are bigger then in the runners..! If that's the case, you could gain some top end power at the expense of some low end torque due to increased high RPM flow and a reduction in low RPM's gases velocity! :)

It's something i will do this spring because it's gonna cost next to nothing...!

I guess I'm waiting for the rbc to come out for the 9th gen. Any idea when that might happen?
I think you may misunderstand. The rbc manifold is a manifold used on other vehicles. It will never "come out" for the 9th gen unless someone sells it pre-modded specifically for the k24z7.

I am actually going to have mine modified next week probably, I may ask the shop if they would consider doing something like that, because I am assuming quite a few people would buy it

Absolutely. The big question is what to do about injectors though. Full Race seems to be going with the 8th gen parts... I really don't want to have to buy injectors just to do the manifold, but if I want to head towards a turbo build it makes perfect sense...I guess for NA it makes sense to do the 9th gen injectors (and have the rbc modded to accept them)... just thinking out loud here.

I kind of like using the 8th gen injectors, I got better gas mileage after switching to the 8th gens, and there are more injector options available right now at that size

Do 8thgen injectors. You have a huge variety of aftermarket options, not to mention if you go mild n/a you have the big grandaddy of all injectors the rdx 410cc's that support up to about 280 whp n/a

How much HP would you say the stock 310s are able to support?

Hard to say without seeing it by myself... You may have a gain but ultimately the long runner design of the stock manifold is what is gonna hold top end power back!

bout 220 hp give or take. Past that is hit or miss.
Well then I may need new injectors sooner than I thought, because just with flashpro ill be at least at 220 not to mention if I add the throttle body, pulleys, clutch, and flywheel.

King Motorsports has an I.M. porting service... think they might sell RBC's as well. It would be worth looking into, or atleast checking out their website.
