    IT7 rear end ratio guestion

    Anyone out there using the 5.17 rear end ratio? I know the 4.88 seems to be popular, why not use the 5.17 for more acceleration? I've currently got the stock rear end ratio, I believe it's 4.02 or something close. Thanks in advance Jason

    2nd gen RX7 motors

    I've contacted several RX7 builders about motors for prices, but anyone have opinions on power, reliability or ease of doing business? SAS, Speedsource and RotaryRacing are those I've talked with. Any input would be appreciated.
