there are kits like zex and other that send the nitrous in stages so it not dosent do as much danage, that is a very good point many people dont think of the surge nitrous put on your motor.plus nitrous on a turbo motor acts like a intercooler so u get more hp out of a shot, as for the spray bar on the intercooler,only thing i see that to be good for is for people that dont have any other mod to do to there car,but there are more cheaper ways like c02 or alkiy/water injection
