Who cares about weight when the 4,600 lb. (gross weight) R35 Skyline is beating down the new Z06 and turbo Porsche's? And doing it with only 473hp and 433tq!? Somebody either has to much money, and or time to be considering this venture. Thats irregardless this being a Z forum; it just does not make economical or even practical sense when you can spend much less to make much more hp from a TT Z motor.
