neither, ......turbo kit, hondata, stock ls.....good for 13-14 psi all day long. on that setup your looking at a fairly reliable 250-270 whp car. and in an integra thats a 12 on slicks or 13-14 sec quarter on street tires. not bad for the amount of money youll spend on that setup. if you build the motor and run high boost your just gonna start breaking more stuff than your wallet can keep up with. like in my case....i spent over 6000 building my JUST MY MOTOR and it never ends!!
