    ok, my question is, I never drove a LS_VTEC, and what I am wondering is, how better is a LS vtec than a c1, I think, I know that a gsr is more reliable, but a ls has little bit more torque, so ok, who would win in a race like that,

    a LSVTEC with Si head and Si tranny, in a DC2 boddy

    a GSR with a Si head, and a GSR tranny, in a EM1 (civic si 2000)

    or a regular GSR, in a DC2 (my car)

    all of them are basically stock, only bolt ons, like header intake, exhaust,

    the reason I am asking that is, one guy has a LS VTEC set up with si head and gsr tranny and he sais that he will walk on c5, or c1 easilly, so did somebody race one, can somebody tell me the difference in terms of performance,

    oh eah, and I know the LS has like 1820cc, or something like that a c1 block has like 1790cc, I am not sure on the numbers,

    ok, so help me out on this one,

    You can't predict those things. A lot of it comes down to driving ability and other factors. I mean hell if I had a chevy 454 under my teg I would stop every one exept the fact that my all season tires would just spin as any other car with traction kick my sorry @$$.

    Given the same driver?

    I think a properly built LS/VTEC could take an ITR in a straight line, but not by too much. In the twisties, however, the ITR would shine and leave the poor little LS/VTEC DC2 a little butt hurt afterward.

    So in other words, you better hope either A- you're a better driver or B- their motor blows. Properly built? LS/VTEC ownz j00!

    Why do you say that?

    Why do you think c5 will be so much better than a ls/vtec on an autocross course?

    comparing both it would seem that the ls bottom will yield more hp and tq figures only due to the increase in displacement.

    So, if both drivers launched exactly the same, both had the same 60fts, and reaction, with both motors running the same tranny, oil, ecu "timing maps and ignition maps", and both drivers and cars weighing the same, then I would guess the ls bottom would be ahead by a hair.


    There are far too many variables to take into consideration, but the LSVTEC motor if built right will produce great figures for long periods of time.

    stock for "stock", driver for driver, traction for traction, environment for enviroment, wind for wind, the ITR will walk an LS/VTEC.

    LS/vtec's 'stock' have like 9.4:1 compression
    ITR has 11.1:1
    ITR has larger cams than a b16 head
    ITR has better intake manifold than a b16 head
    ITR revs higher than a b16 head
    ITR has an ecu matched to its motor with proper maps
    ITR has a better geared tranny than an LS
    ITR has an LSD
