I know the SI and my CX are differant motors... but can a snatch an SI intake manifold and strap it on inplace of my CX manifold to get some more air flow? because anyone who has seen a CX instake system KNOWS its literally like soda straw small... would the SI manifold just bolt up? Any problems? Just for shits and giggles I think me and Rene are gonna build a custom CAI for the CX and give my raging 70hp a um, 1 WHP @ 7000 rpm gain :devil: :bloated:

But, my question is will the Si manifold (from 92-95 civic) bolt onto my (93) CX ?

Well me and my friend nick threw on a Si/EX intake manifold on his VX HB and it worked out allright. I cant imagine how small the throttle body on a CX is because my friend Nick's was seriously like 1.5" in diameter.
:hehehe: :hehehe: :hehehe: Kinda funny if you ask me. But now he's to the normal size of a EX/Si. :evillaugh:

bolt pattern's the same, so are the intake ports, but I'm not too sure about the coolant ports

can u reply crx: i have a 95 civic vx and i also have the si/ex intake manifold and the ecu. how do i go about changing it. will the check light come on if i swap it... i try to put the si ecu it work 4awhile but check light comes on.

Can I use the header even though the Si is a 1.6 and mines a big honkin 1.5 ? What about the throttle body? injectors? I figure why the hell not it certainly cant HURT performance ~ I mean you try suckin through a soda straw and see how long you can do it :devil:
