Just about every month I am going to be doing something new to my car...Last month I got new rims and tires, and this month I just got new lowering sprngs and new shocks and struts.... I want to do as many bolt ons as possible, maybe one or 2 a month. I already have an idea of which ones to do, but eventually I do want to supercharge my car (03 GT). My question is what bolt on's should I avoid getting that may end up being useless once I get a supercharger down the line? Just so I don't waste any money now, and direct my money towards better parts...

 

don't really know which ones might be negated once u get a supercharger. but a 75mm throttle body + plenum would be a good one to do as it will give you gains while N/A, and even bigger gains once your supercharged.

 

If you are going with a Kenne Bell, Steeda, Eaton, Roush, etc don't bother with a plenum, you can't use it.
Underdrive pullies also can't be used.
Depending on what supercharger you go with, a CAI might not be able to be used

 

good, that is helpful...If I go with a vortech, will I be able to use the tb/p and CAI....I've also heard that about the no underdrive pullies....Also to stay at or below 3.73's, that 4.10's will be too much...

 

pullies, cai possibly, higher gears, cams (not neccessarily a bolt on)

 

4.10's are a blast with the Kenne Bell
but I've heard I'll need to shift into 5th before the 1/4 mile is up (I hope to go to the track Sunday to find out for sure ) but on the street, it's awesome!!!

I don't think you can use the CAI with a Vortech, but yes, you can use the tb/p

 

oops

 

forget everything else, finish up your suspension with some Control arms, and sticky tires. Get a set of 3.73's and a full exhaust with some longtube headers. Add to that your Vortech and you won't need any other bolt ons, except I would get a TB/Plenum combo too
