I have a pretty much all stock 2004 GT 5-Speed. What are some good power mods to get first.? Im looking for around 300-350 hp right now. Dont need too much, too fast. Thanks

 

A CAI, tuner or gears would be a good start.

 

What he said.

Gears will not boost hp but will make it faster off the line

 

LOL you will never hit 300-350 with bolt ons only. You'll have to dig into the engine or go forced induction. Keep in mind the 99-04 get only make 220 rwhp..
My buddy with cams and ported heads, and full exhaust made just below 300

 

He can bolt on nitrous, but nitrous sucks.

 

Well I probably wont go F/I until I get enough money to do it right. I heard pullies should not be ran if running a S/C. So a should I get under drive pullies, a CAI, Gears, and a tuner.? I know for a fact I'm doing a full exhaust.

 

Thats alot of money right there.

 

Best hp mods for the buck are cold air intake, upper plenum, offroad x-pipe and a tuner.

 

All these guys are right and I'm not gunna beat a dead horse and say the same thing. Lol

 

But in all reality... the best money I have spent was on the gears.

 

Alright. Should i go with 3:73 or 4:10

 

I went with 373.

And love it, my car is not a Dd.

I think 410 is too much imo

 

My car is a DD. Except im not driving all the time. Couple times a day

 

Don't be scared of the gear

4.10s all the way

 

I wish I would have went with 4.10's

 

I'm not trying to steal the thread, but it's just a quick question. How badly would 4:10 gears hurt gas mileage on a 2004 V6?

 

Like to and from work.

How many miles a week do you drive? How much money are you willing to spend on the entertainment budget?

You will lose around 1-2mpg on 3.73, 3-4mpg with 4.10. So figure out which added cost you would be okay with for the extra fun the car will be.

 

I gained mpg with the 3.73's
You will really only lose if you do alot of highway driving.

 

Mine's a DD and I drive on the highway 4/5 days a week :/

 

its all about driving habits. You could see a gain in city driving if you are using a higher gear than you did before the gear swap.
