Doubt it. The Cobalt is a VERY good handling platform (up until Renaults "factory" race car lapped The 'Ring, the SS/TC was the fastest production FWD car around it)...it might be about even, but no way it'll "own" a Cobalt SS, especially a modified one.RX-8 isn't even supposed to be fast in a straight line either, it's more of a touring car. Pretty sure your friend would own you around most tracks though.
True or one 13b and one 20b, this way you have a spare housing, apex and rotor, just in case. almost everything is interchangeable, depending on the year and series of that particular engine.Its not "4" rotor engines put together, it's 2, 13B engines. There's two rotors in the 13B, and three rotors in the 20B.
