the skyline would win (imo)...if u launched both cars the 33 would be faster....
ofcourse the 33 would seem slower wen u just takin off normally, cause of turbo lag.....superchargers as u prolly know eliminate this lag + a 3ltr is gona help.
u dont have to spend much money on a skyline to get it moving faster...turbo bak exhaust, ecu, boost, fmic, done, and alot fatser than a freggin accord.
EDIT: off the line ull always struggle if u dont launch a skyline...
