    HKS 256 cams

    I was on FB a few days ago following a thread on a page about cams, some said that you can drop in some HKS 256 duration cams on a completely stock engine and not have to worry about supporting mods...and that includes mapping!!

    surely that can't the case?

    Prob don’t have to get them mapped but not sure you’d see any benefit. 256 is the same as the poncam isn’t it which doesn’t need springs etc done when fitting.

    no it was mentioned completely drop in with no work at all.

    he did say it made his car feel amazing...so begs q if the cams don't make any difference why are they being sold?

    In theory if the map has enough 'headroom' then the extra flow will be measured by the MAF and the fuelling and ignition should be pretty close.
    I'd imagine if the ECU is completely stock it'd run into fuel-cut pretty soon though.
    I'd also be dubious about getting near even the stock rev limit too without some stiffer springs....
