Thats just strait ignorance. Every racecar breaks. Drag cars, LeMans cars, Busch cars, monster trucks, boats, Karts, motor cycles...EVERY KIND OF RACING VEHICAL BREAKS!
Problems only multiply when you take a 4 cylinder car thats engine has a stroke that rivals that of a 383, and run it at 6000+rpm for long periods of time w/o any sort of aftermarket internal, fuel, or ignition mods. OEM eco-boxes just arent made to run that way. Hence the reasoning to do a complete build with the best parts i can possibly find for it.
