Ok firstly, have you ever drove a glanza, im guessing you probably have or you wouldnt be getting one. Im also guessing you know they are a very light car and that if you were to put say the power of a civic type r which is approx 200bhp in a glanza - it will be a very quick car and most certainly put a civic type r and many other cars to shame....but how quick do you class as quick?... how fast do you want it...? you can quite easily get a starlet to 200bhp, want to go further? bigger turbo? more boost? approx 200-270bhp...chasing even more power? 5EFTE BIGGER turbo and MORE boost.... how fast do you want it?
