I am going the N20 route this spring and I'm buying the parts now. I need to know several things so I'll rely on you experienced N20 users. What is the ideal system? VCN-1000 or a Nitrous Express? I hear multiple things on both and was wondering if the Venom is really worth the 200 extra over the Nitrous Express. Does NOS perform equally? Also, I want to do my best to hit high 13's. What mods will I need to get there without a engine rebuild? I'm not rebuilding till next winter. Finally, Best place to buy this stuff is??? Thanks alot guys.

a few points here for ya !
as far as the reliability I like NOS brand the silonoids are easy to rebuild and its strait forward, the venom i have heard mixed emotions about the system as far as reliability and the sticking of the injection unit, NX systems are almost but not quite like the NOS system but the reliability is the same just harder to rebuild the silonids.
As far as mods go I have a list o mods on my car if ya like to check them out and i'm adding a S-afc to the list also
