i am driving EF9 for the past 3 years and so far i have no plan to sell this great car - i believe EF9 very light and the best car for cornering. as for the parts, no problems to get it lah. engine parts of coz can use from any big vtec w/o any problems.
just like what superstreet said - strip down the rear interior, install Vision carbon kevlar seat for the driver, with steering extension kit, no gadgets at all except for microtech LT10s handheld hidden in the glove box......oh n then install the rare chargespeed spoiler and roll on type x's or BRs with 55s rubber... ohhhhhhhhhhh stim stim.
btw, the EF9 is also preferred not just for drag or track racing...but for drifting as well.. mueheheheh
