I was wondering where to place the nitrous nozzle and a b18b intake, i had it on a curve on the intake but it created a backfire and my intake caught on fire, so im just double checking where it should be? I was also running a 42 and a 22 n.o.s. jets. i just looked it up and i realized it was a lean shot, and i also wanted to double check what is stock fuel pressure on a b18b ls. i also have stock pump. im now going to down jet to a 50, and was wondering what jets i need for that. thanks
