PI Motor help

[Late4Work]

Well guys i just bought an 03 4.6.....now i know what do do with a NPI motor but not sure what the differences r with the PI motor.....compression, heads, all that good stuff......some input would be helpfull

Compression is the same, heads and cams are better, intake is better, thottle body and plenum are the same. the main issue you will have is finding a way to mount your coilpacks, since PI motor's use a coil on plug system.

All the sensors and plug's are the same, however you have a second coolant sensor the PI motor does not have a location for, you can have the intake tapped with a 3/6 NPT to take care of that, have fun!

Ok so u say the cams and intake is better....but would u say that comp cams and patriot heads or trick flow intake r better......HP per dollar would it be worth it??

I would avoid Patriot, go to Modular Depot or Modular Fords and do a search, their name is pretty much poo in our world. Otherwise, yes definately worth the money.
