Hey guys im new to this forum and I know that the is300s are not fast out of the box. Im coming from a 265whp 228ft.lb 6-speed acura TL which just got totaled. I have been looking at a 2003 lexus is300 sport e-shift and i wanted to know how fast can I get a N/A to go? I have been looking around the forums and I know that a good intake and exhuast will get me somewhere around 190 - 200 whp. If i was to do headers, cams, pullies (if they make them), and spacers, which ones are the ones to get, and would it be worth it. Im trying to keep the car n/a for now, so turbo is not an option. Thanks alot guys.. its hard to replace a car you have poured soo much blood and sweat into like my acura.
