I will begin modding my 2001 grand prix gt soon.Just a quick question and a list of my mods ill be doing.What do you think ill gain with these mods?0-60,1/4 and top speed.
My guess would be 50extra hp and 40lbs ft extra.and 0-60 under 7sec,1/4 hopefully mid-high 14's.and top speed about 145.Any ideas and help?
