RE: Non turbo horsepower mods
Theres not too many mods out there for your motor (420a) ...well not many that will seriously increase your HP/TQ.
Its simply not a powerful motor. Any mods (with the exception of forced induction, of course) that you do to that motor will likely result in single digit gains...
