most people i know start out with some minor bolt ons...since when ure a noobie to the sports...thats all u know...
then later on move onto bigger things...supercharging or turbocharging...

i find this debate rather pointless...
ull have to start out from somewhere...
not all noobies will know about boosting...and not everyone can spend 3k at once for a turbokit...
plus...u have to know ur shish aniway...

imho...plan well ahead...dont rush into buying things too fast...
