    ok, first off you are prolly wondering why im not doing going b20 vtec. $. ive got a b18a head that i can get for dirt cheap and am planning on sending that into a machine shop for some p&p action asap.

    so, what wiring issues will i have as far as not having vtec in an si hatch?

    btw, project car is a 92 hatch si w/60k miles on body, minor driver side damage(and the usual rust spot).rolling chassis only.

    im sure i will have many many many more q's.

    plan

    b20 non vtec w/ crower 403/404 cams, also will prolly be bringing the compression up..

    or if i cant get a b20 cheap and i find a b18a/b, then im going LSi in the hatch with the same head setup as above.

    i know ;) thats why i want a shortblock.

    the reason im not getting a full b20 was cause i was originally planning on doing an LSi w/cams to the teg and found a head for it so i could still drive it while i sent the head in for machine work. but... then the hatch showed up for dirt cheap and i decided that displacement would be nice to have.

    you might as well though.

    it will save you a buttload of wiring problems cuz its obd2, and you can sell your LS head for the same you could a b20 head... and its probably cheaper to buy both

    i assume you mean the b18a head vs the b20 block?
    or do you mean a vtec head vs a b18a/b head?

    if you ment the fisrt...

    true.

    if u mean vtec head-
    im gonna stick with the non vtec head cause after p&p+cams etc etc it will be as good if not better than a vtec head. oh no.. i will have a rough idle :roll:. all vtec is is a more agressive cam(correct me if im wrong). why do i need it if im plan to be running a very agressive cam? i dont. it will just be A......(;) thanks)LOT more money for a head.

    VTEC is only fuel economy down low and high lift up high, like a balance.


    Get a decent tranny for your setup, i recommend a GSR or more a more nasty gearing go with the JDM itr unit/SiR/usdm R unit.
