    What is the difference between a regular Civic and a CVCC?

    I see some older 70's Civics advertised as CVCC and some do not advertise that.
    Is there a difference?
    If so, what is that difference?
    Is it better to have a CVCC Civic?

    I'm not the best to speak on this but the CVCC 1500 is obviously bigger & heavier that the standard 1200 with a cast-iron block instead of alloy, combined with their stricter emissions priorities largely negating any power gain and giving the cars a heavier more substantial feel overall.

    I gather early examples didn't rev as happily as 1200's and their carburetors are far more complicated to create separate "rich" & lean fuel mixtures for the "stratified charge" within the engine which can cause headaches trying to stay original. And if the cars are neglected & allowed to overheat the extra heat generated by the lean mixtures can blow head gaskets & even warp blocks which some don't notice 'till they've replaced a few head gaskets. The 1500 is closely related to early Accord & Prelude 1600 & 1800 engines (also CVCC in the US) which might make those conversions easier.

    For those that don't mention which engine the have, 1200/SB non-CVCC have exhaust out the front "crossfow" , 1500 CVCC have it out the back "non-crossflow" though if you find pictures you might spot the extended front paneling of the CVCC cars.

    If you're interested in "speed" then the 1stgen Civic engine isn't your best choice 1200 or CVCC. Now if you go ahead and swap in a D series engine you can have a little demon on your hands.

    If you want more space for a swap, a cvcc is best, if you want a fast oldschool car and engine, the 1200.I have both.

    We didn't get the CVCC down here but I'd like to mention that the 1200 / 1335 engines were made for JDM -RS models which had 4:2:1 exhaust headers , twin CV carbs and a different cam profile.

    On my '81 Civic when I was young and couldn't afford an Accord I found the headers and carbs from an RS at the wreckers yard and had a cam reground to suit.
    The transformation was very satisfying with no problems and the car remained in 'spec' to JDM type RS

    The Civic 'S' sold in NZ only differed from the base model with addition of sunroof, spoiler and stripe.
