lol. maybe your car does not have lots of problems but it seems everyday you have a new thread complaining about something. i think you just complain too much about stupid shit. no offense or anything
all i would do to an auto is cai and exhaust. even those are not going to net you much power. maybe 5hp at most. if you are going to keep the car do a 5spd swap and then mod away. other than s50 cams you are pretty limiited for making any power.
at 120k your motor has lots of good years left assuming it is well maintained. based on many of your posts that sounds iffy
if you motor is healthy i would do the tranny swap and then get the trm turbo kit, $4500ish with tuning and everythign, and have fun with the great power you will have.
