Default Stock 03 Mustang

Hey Im new to all this stuff. I have a stock mustang and was wondering what would be some good things to do to it to increase HP, torque, etc.



A few things Im looking for specifically:

Exhaust

Chip



With the chip I was wondering, is it possible to get a setup where I can connect the comp to a laptop in the car and get readouts on stuff? Ive seen it on TV shows and movies but Im not sure how that works.



Thanks guys.
*EDIT Mustang is an 03

What I'm planning down the road for my stock 04 gt is:

Cold Air Intake
75mm Throttle Body and Plenum

Long Headers
X-Pipe
Cat-Back

Tune

That will really open up the breathing on the 4.6 2v engine. I'm hoping to see about 50hp increase with a strong increase through the powerband.


For a 2003/2004 you won't use a chip, you'll use a tuner which will flash your computer control.

what year is your car?

catback, gears/tune is a good place to start on a 99-04 GT

PIswap and gears/tune if its 96-98 GT

I hate to break it to you, but there is no way that you will see even 50 crank hp with that, let alone rwhp. I would say the mods you mentioned are good for about 20 rwhp at best.

My dad saw 45rwhp from BBK LT's, BBK H Pipe, Flowmasters, and Diablo. IMO Gears is a must with those cars. He went with 3.73 looking for boost later on...

What's that?

Cold Air Intake
X-Pipe
Cat-Back
What is a good brand name and where can I get it?

Tune
Tune what?

Ive heard people talk about changing their gear ratios. What does that mean and is it a good thing?
Also if you guys could give approx. prices that would be cool.
Thanks

Gears. 7.33s and a 250 shot of nitrous. And then add 4 turbonators. And then twin turbos pushing 30 psi. But dont build the motor. Thats just dumb to build the motor.

And then when your car is a complete piece of ****, use the search function to find out why.
