f22 IM vs h23 IM help

[pupildel]

hey cb's can anyone tell me the different between an f22 and a h23 intake manifold

cuz i jus readed the intake manifold DIY http://www.cb7tuner.com/vbb/showthread.php?t=16242

and i jus want to know the different between those two like (power gain,air flow, throttle response,etc.) before i start working on my cb cuz thats alot of work and time so yea....

H23's plenum(the top part) is larger so you're going to have more air flowing in. However for some reason people don't consider the H22 adapter which allows fitment of the Skunk2 and Euro R manifolds which are somewhat larger.

wat does this mean for my car cb7 f22a1

It means if you use the adapter plate you can run these "supposedly superior" intake manifolds that wont normally bolt up/line up. Which is pointless, people go this route for the bling factor most of the time and besides most everyone on this site who does the manifold swap isnt pairing it with headwork, a new cam, or bottom end built with any form of tuning to cary a powerband high enough for a Skunk manifold.

Just do the typical and proven F22A6 manifold, or the H23 one. If you want to, you can use the F22A6 lower runners with the larger H23 plenum on top.

This.

I have the option of using an entire H23 IM or using the runners and IAB plate from an A6 with the H23 plenum on top. What would you all suggest?

There was a thread that went WAAY into the differences, but i think the bottom line was the A6 runners were like .5'' longer i believe?

Either way, nothing to split hairs about but everyone agrees the h23 plenum is larger in volume and i believe the H23 throttle body is larger as well, but dont quote me on that.

Just run whatever bottom end you already have and run the h23 upper half plenum/ throttle body.
