Ok i just want a lil boost in my car. maybe like 4-7psi and i was thinking about a kit like this eBay Motors: 95-97 98 NISSAN 240SX/200SX INTERCOOLER+PIPING S14/KA24 (item 310032356358 end time Mar-20-08 18:37:57 PDT) then slapping a turbo on there just wondering what should i do to the motor internally before i do this like changin headgasket etc.
