70mm Throttle body

I would wait for the tb , if you have only put a k&n filter the tb will not help you any ,

First mod : 373 gears , with the gears you will have to get a speed cal to help with your rpm's/

2nd mod : pullies , these are just bolt on , you might have to get a smaller belt but you shouldn't have too.

3rd mod : h/x pipe . you will have to get MIL to keep the check engine lights off.

4th mod: headers , these just bolt right on .

5th mod : would drop the car , you will need to get caster/camber plates to keep from wear on the tires.

6th mod : sub-frames , these just get welded on

7th mod : steeda t/a , this is just a bolt on too.

8th mod : new shocks/sturts

9th mod : cat-back system , just a bolt on .. cat-back will have your new mufflers too

10th mod : lower/upper control arms ....

Ok , I am going to stop there , there are many more that you will need to put on the ride but that list of 10 will take a while to get , much money !!!!! But as you will see on this site people build there cars differnt .. so find out what makes you happy and run with it !!!!

But if there is anything that you do for your stang , you must read thru the treads in this site ,, most questions that you have , have been asked and answered about 1,000,000,000 times .
