hey guys, im trying to make my car quicker. the only bad thing is its an automatic but it has exhaust and intake. i was wondering what should i do to the car to make a alot quicker. like the first thing i should buy for it. maybe a tune-up? help greatly appreciated.

 

Do a 4G63t swap....

 

Get a high flow catalitic and a cold air intake that should help a little.

 

how much u think it would cost for the swap? and for them to put it in?
