Um before you make a big purchase i'd do some research. make sure you want fwd cause you could get a gsx
which is a street races worst nightmare.
also if your not a turbo guru then get the 4g63 it's a very kind
motor to the newbie's.
as for crank walk i would bet that you would blow your 420a making it turbo. then finding and blowing a walking 4g63.
If you realy need a turbo rs then put the shit on your self.
i would want to know everything i could about the kit and the install. and it's a little more respectable
