Emissions reasons. Federal law states that the vehicle can not have a bigger engine than was an original option for the vehicle (rangers cant go over a 4.0 by that law). On newer vehicles that, in some states require OBD2 emission inspections, the vehicle will not pass inspection because the VIN on the registration and the VIN in the computer does not match (unless you go big money and have Ford reprogram your computer that way).

 

ouch then...almost every import tuner is breaking federal law...even me...with my lt1 powered rx7...LOL

 

Yes.
