    its about two feet wide from valve cover to valve cover and about 4.5 from crank pully to the end of the transaxle.

    uhm...
    hasport just came out with the H22 into 88-91...
    i think you're gonna have one hell of a time trying to do the H22 into an 87
    hasport.com has the b series mounts
    Hasport Billet Mounts

    whats your budget?
    check out the first gen crx FAQ
    basically the same chassis
    http://hondaswap.com/swap-articles/1st-gen-crx-faq-s-29108/

    the easiest swap for your car would be the 86-87 brown top D16A1 dohc motor from an integra
    about 25 HP increase, cheap if you can find a whole donor car
    requires trans, axles, spindles along with larger brakes
    88-89 black top motor is similar but not vacuum advanced like your car

    i have an 86 CRX si with the D16A1, i'm quite happy with it

    Probably not as bad of a time as me. I am trying to convert my 88 crx si to a rear wheel drive and plant a NSX for the heart of this beast. Everyone is give me crap on how it won't but i gonna show them. Good Luck with your swap bro.

    The H22 engine and tranny won't fit in the 1g engine bay...period


    You'd have the cut the unibody from the fireawall forward and make a tube chassis...thats really the only way I see to get one in, and at that point you might as well as do a K swap


    also, I'd make friends with someone who can make some seriously custom axles and suspension parts

    if you're still looking into this i suggest you buy a wrecked f22 accord for cheap so you have a motor with the same measurments to use as a guide
    mounts are pretty much the same for f and h series

    hasport.com read their instruction sheet to get a general idea

    Theres a company that makes a transmission adapter for the H22 to use the CG transmission off the 86-89 integra (which bolts right into these cars). I could imagine this making it much easier to fit one of these motors into this car. On top of that you dont have to deal with finding custom axles.

    sorry to say but forget it its a nightmare. if u insist on doing it cut the whole front end off the crx go with a tube chassis. look to spend as much money as it would cost as to buy the prelude with the h22
