Unless you have changed the transmission and/or rear end then the transmission you have is a 4L60E and your rear end gear is either a 2.73 or a 3.23 rear. Only the manual cars have 3.42 rear ends in them that is unless you or somebody else swapped it out. The most basic mod there is for the money is the air lid. You said you have a cold air so you might already have this. The air lid is proven to be a very good mod with a price tag of around 100 bucks. I have seen dyno results as high as 12 or 13 HP with just one of these lids. Since your car is an 02 it already has an LS6 intake on it so you are ahead of the game there. Some other fairly basic mods would be some headers, however, with headers you will want a tune because headers tend to make them run rich. Since you are an automatic car if you are ever going to put a sticky tire on the car a torque converter would probably be the best bang for your buck. When my car was stock I picked up .6 of a second just from a converter, of course that was on ET streets which dead hook at the track, I went with a Yank SS3600. This converter will also allow for the spraying of nitrous and its tight enough you won't blow through it on the bottle. |
