because i talk to the people who run turbo's on their 3's on a daily basis. i talk to the guy who built the turbo kit on a monthly basis.
and no offence, but i'd take what i get from some tech's regarding aftermarket performance with a grain of salt. they dont know what the cars can handle becuase they aren't modding them.
it just makes no sense to me that if you have a motor opened up, and you are going to be buying internals, why you wouldn't just buy FORGED internals from the get go.
i never said i know everything but i make sure i do proper research and talk to the people who are pushing things to the limits. not someone who works on fixing cars when regular people have problems.
boost is like crack. you're going to want more. when you crank up the power, you'll break something and i'll be here to tell you i told you so.
