there is a single cam ZC motor which has more then 108hp... i'm not sure exactly i knew at one time.... it is not the same motor as the stock si's have either... it has the same displacement but the bore is smaller and stroke longer.... not by much but enough to see on paper....

when you said cx did you mean vx there?? cause cx never came with vtec... while the vx had a totally different form of vtec from pretty much all other vtec motors... if you have a hynes manual you can see the difference its kinda weird how it works but meh... i'm sure if pulovr was on now he would find a nice picture of what i'm talking about

Wrong.
Thank-you Come again.
Good try though.
Some of the ZC's did come with SOHC engines, but they were not all Vtec ones. Also, they came in NON vtec as well.
Some also came as caburated instead of FI.
Trust me on this.
Some of the SOHC ZC non Vtec came out of the Civic Ferio 4WD, (as well as some other Honda cars). Because of this, they had more torque than thier North American conterpart.
Ie......if you took a JDM ZC SOHC motor out of the above car, and switched out the carburator for a FI set-up, you would have the HP of the North American Si, but with more torque to boot. Oh yeah, that's also with NO Vtec either.
Do a few mods like CAI, header, FPR, exhaust, and you'd have a car that would drive circles around the Si.
and because the valve cover looks EXACTLY the same as the wimpy D15 one, people would just look the other way, and not take notice. hehe little do they know. 
By the way, SOHC NON Vtec ZC's start at around $300-$350. Not bad for what you get.
for a civic board peoepl dotn' knwo to much...it will be a SOHC zc that basically is the "si" usdm motor...it has 108 ish hp..it is basically the same motor the stock si's have...the 130 hp zc is the DOHC one....

SOHC ZC outta the EF's is rated at 120HP, while the DOHC ZC is rated b/w 130-140HP(depends on which source ya look it up.)
ZC VTEC is whole other story though.
ZC was for the EF7(JDM Si) and b16 is from the EF8(SiR)
