Hello all, I have a 2003 Mustang GT. I installed a Pro Charger with 3:73 gears and all the goodies to go with it. Problem is I'm not satisfied with the 400 HP i have to the wheels now. I know nothing about this stuff and want to know what i can do next for more power with out doing a new motor or blowing the stock motor. I would like to do cams and heads but I don't know if it is worth the money since I've already installed a pro charger. Any help would be appreciated!!

So far I've done:

P1D Pro Charger
3:73 Gears
BBK ceramic headers
Flow master 40 series exhaust
summit off road pipe
pro 5 0 shifter
eibach springs

 

If you are at 400hp on a 2V, I wouldn't push it too much further until you upgrade the engine internals, I.e. Crank, pistons etc.. The 2V stuff is cast, not forged like the cobras are. So I would upgrade those, (the block should be fine) Then maybe turn up the boost, smaller pulley, bigger SC, whatever you want.

Other than the eibach springs have you done any suspension mods? Is this a street car? Drag car? Auto x?

 

Got long tube headers?

 

it is just a toy that used to be my every day driver, now its a work in progress but the problem is I know absolutely nothing about cars so it makes it hard to know what to do next! id be happy to get 500 HP at the wheels. all I've done is the eibach springs as far as suspension and I have short headers

 

Well, the shorty headers are doing nothing for ya, get long tubes, that'll free up some ponies...Not a fun install by any means.
