Im looking for a build list for an n/a 2003 mustang v6. Im hoping I can find one that would put me around 280- 300hp. Im assuming I would have to do a cam, headers, intake manifold, injectors, fuel pump, and ect.. Im just looking to see if someone has done it before and if its possible. I also would like to know the parts you used to achieve this goal and where I can find them. I have a 3k budget but I can go a little over. Thanks!

Supercharger would be the best way to get up near 300HP, but that will cost you more than $3K for the kit, supporting mods and the tune.

N/A you'd probably have to start with a 4.2L engine, heads with some port work, a camshaft, full exhaust, tune, etc etc. Again, not cheap unless you have a good source of parts at dirt cheap pricing.


Don't take this the wrong way, but for LESS than $3K you can probably swap in a V8 engine and hit that number more easily.

Check out titan engines. For 3k + shipping & core they will get you close to 300hp by bore & stroke the 3.8 to a 4.3 . This is what they told me. So take a look an see what you think.

That's aiming pretty high, but you can get pretty close:
rebuilt 4.2 long block ....$1745
Pypes true dual exhaust $636
Diablo Flash Tuner ........$600
Cold air intake set ..........$50

Total: $3031

Of course there will be all the ancillary things like gaskets and hoses you will also need that I didn't include and you'll have to do all the work yourself.

This should be good for approx 270 hp NA
