What nitrous system you are going to run? Cause both got 99'*. I am still deciding on running on NOS (I am too lazy to type out nitrous anymore) or maybe adapating zzperformance'* supercharger for the GP on my car. I know NOS would be cheaper and more fun but I think our pistons could only take about a 55 shot or so and if you ran more of a shot, you have to upgrade the igintion to one heat range colder spark plugs and MSD igintion and such. If I do NOS, I was thinking the Zex kit (its dry) since it adjusts to bottle pressure and such. Just my thoughts, just give me a hint and maybe we can help each other out.
