nissan bugger s are a group of cunning fellows.. they make the skyline under performance for its spec.. why? cuz it was made to be modified... the cars are made for higher performance but need to detune they to oblige to jap law... the gtr is a heavy, bigger transmission power loss etc.. in stock trim u can get smoke easily by lighter 4 bangers on the streets.... but since ur a rb26 owner, u should know that the character of the 26 that the power only comes after 5k rpm in stock trim.. its a high rev eng... on the streets, where can u put that type of rpm.. those light 4 bangers are good from 3 to 6k rpm. of course its difficult to win in an accelerative comparison.. get a power fc and retune for higher torque at lower rpm, it make street driving alot more enjoyable..
