If you can affort it the best way (and best performance) is to take your car to a place like Omex with subtle mods such as a decat, full exhaust, intercooler. Let them install an ECU and map the car for approximately 12psi or 13psi.
If I modified my Starlet, this is what I'd do... a proper job!
You mean scared of spending money on the right things! People spend £600 on an intercooler and £600 for a full exhaust system which may give them 10bhp for the decat and 5bhp for the rest of the exhaust system if that.
An ECU alone could get you three times that figure without any other mods
is it worth modding it. on my old rs125 aprilia there were loads of mods for it but they made hardly any difference at all. in the end i made it sound good and left it at that
