Hello everyone! I'm new to the site and looking for some good advice. I'm wondering what my next step should be in building my 2003 mustang GT w/ Auto trans. So far my mod list is: Procharger stage II P-1 SC kit with a 12lbs. pully, shift kit, 3:55 gears, MM K-member brace, MM weld in subframes, MM strut tower brace, Bassani cat back, bassani off road mid-pipe, and JBA ceramic coated shorty headers. I'm running with 18X9 chrome bullet wheels for now. I want the car to make more power than it is right now. My next mod is going to be a properly sized stall but I wanted to do something along with it but I wasn't sure what would be a good next step. I was thinking about a MMR 900 stroker shortblock but I wasn't sure if it is too early to be thinking about that or if that would even add that much HP to the car. Are there any smaller mods that I should be thinking about to add some HP like a intake manifold and TB? I just want to know what the next best step would be! Thanks for any help you guys can give me and thanks for reading.
