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.

What numbers is the car putting down now? Whats the fuel system? Yeah if you get a new shortblock it probably wont make much more power, BUTTTT, you can then run more boost which will then make plenty of more power....but along with more power you have to make sure you have the fuel system to handle the power as well. A t.b. and intake plenum would not be a bad idea as it will add a little. But the proper size stall will feel like a huge kick in the pants I bet with the auto! Let us know your fuel system and dyno numbers now to help for your future
