Hm... H23 or F22A6 runners?

[shadowdlink]

So guys? Which one will benefit my f22a1 set up more?(P12 ECU, 4-2-1 ebay headers, short ram intake, 2.25 Magnaflow exhaust.)
I already have an H23 throttle body, H23 plenum, and a gutted AIB plate. Which runners should I use? The H23 runners that came with the entire h23 IM set up, or should I go to the junkyard and get myself the runners from an A6?

*Honestly* I don't think it makes a huge difference.

It's 1/2 an inch length diifference IIRC, maybe a difference of 1 hp or 1 ft lb?

i was under the impression hseries wouldnt bolt up to the f head?

sry just curious correct me if im wrong..

H22 runners won't bolt up to the F22.

[Accrdwgnguy]

I'm using the H23 runners, cuz I got an entire H23 IM off ebay for cheap.

But the A6 runners have more easily serviced EGR ports

[shadowdlink]

Yeah, I was thinking the A6 runners since they have the EGR ports more accessible than the H23 ones. Plus, the h23 IM didn't really come with supports for the IM.

I just wanted a second opinion, so I think I'll go with the A6 runners. Thanks guys.

probably more than that...the length of the runner needs to match the rpm that you are revving to. there's a logarithm to calculate the sound waves and is especially important with ITB's.
