Heh, I wouldn't even call that racing.. I'd call it "accellerating hard from a stop light whilst another car does the same until both cars reach the speed limit, and seeing who's gets there faster."
I don't see how it's unsafe unless the speed surpasses the speed limit.
You should've asked about the turbo anyways! MY buddy's dad bought a turbo for his Geo Tracker from a junkyard for $50, then retrofitted it on for next to nothing. Cheap and badass power!
