Hey guys i just grabbed a 2001 gtp about a 1month ago with 200k miles but the engine and trans only have 60,000k miles on it what are some things that i should do before i start modding as far as maintence? Of course in time the mods will come but first i want to make sure that the vehicle is ready to handle the mods also engine and supercharger questions: what is good oil to usefor the supercharger? Any sparkplugs that are good choices?
