re: them havin to be rebuilt every race....
not so true, i worked on a team that was running 2 rx7's and rebuilding motors seasonally. they blew a couple on the dyno testing limits etc first though.
sure the high hp race motors have to be rebuilt everyrace, but dont the top fuel pistons...
haha my datsun 1971 1200 ute does 80mph flat stick WHAT A BEASTIE!
im sure the motor has more in it (hectic 1.2 liter) but the ute has tallish dif ratio. im hopeing my 1600 will go a bit better! ( maybe even 100mph :O) haha
hopefully track days will stop me needing to do dumb shit on the street...
