While I do agree with everyone here that the 4g63/4 engines are the way to go, there are people who specialize in the 420A engine. If you are dead set on using the 420A, we could be a little more helpfull

. Try HahnRacecraft, SBR , Modern Performance or any of the vendors listed on this site.

If you are wanting to put "ass loads" of boost down something, sell what you have and buy a GS-T or GSX.
