Do some GTI parts fit on TSI's? Like coilovers,SRI/CAI, etc? I do not currently own a golf, however I joined the forums to gain insight and learn before buying anything. I want a GTI, however having just been a fresh college grad starting work in 3 weeks, I'd be barely cutting it with payments for one, so a TSI would suffice probably. I don't plan on modding much in terms of trying to race, drag, etc.
