A few questions about Nitrous

i have a stage 2 NOS 5115 kit installed on mine with 125 jets, gained 100 rwhp and 160 rwtq, definitely a great investment. a stage one will still give you pretty good gains, and you dont need an extra fuel pump to support it. it is always advised to go with colder plugs and lower timing when using nitrous however, which will lower your NA power (my timing is at 8). I'd suggest looking for kits on the stangnet and corral classifieds, they are usually always kits for sale, and none of the parts should really wear out unless abused. help some of that helps, even with a stage one it will feel like a new car!
