This will be a thread to discuss the aftermarket ability, aftermarket, f/i, all motor, and everything else performance for the J engines. You guys can ask questions and inquire about possible things you can do with the motors. If i don't know the answer, I will get into contact with someone that does. Most of the theories that have been around are bull **** and completely wrong. Most turbo and nitrous builds have been done wrong. I am here and I'm sure other will be able to chime in to discuss how we can make a lot of power out of these motors. If someone doesn't believe a fact because they have been told its something else by someone else, i can certainly point you to the truth. This is what I came back to do, to help you guys. I will be putting all the important discoveries and info in the first post.
