nitrous?

For a 150 shot or less, you are wasting your money with a direct port kit. By direct port, I mean a system with 1 nozzle per cylinder.

A single nozzle or plate kit is the way to go. It will save you a ton of money and will be alot simpler to install.

With a single nozzle kit, the nozzle should be mounted 6-10" in front of the throttle body in the intake piping. With a plate kit, the plate fits between the upper and lower intake manifolds.
