Looking good man,i just did the same thing to the front of my truck,except i just made 1 long cut and installed 1 12" pusher and it is controlled by the AEM or EMS4.I like were this is going.
Dude just get a new ka24de and stop fuckin around.I have been through 2 motors to your one,and it's not a money thing,you can get a ka for cheap.Hope to see you at JCCS
