who makes the best n20 plate systems. I am leaning towards the nitrous express kit right now because i have heard that they have a better design. also i have heard that the n express kits are measeured in wheel horsepower not flywheel. any input would be great....

nobody has an opinion on the best n20 kits for a carb application?

Im running a NOS cheater kit( shot up to 250)on my carbed 406. I like the NOS kit myself, I havent used a NX kit before.

I've heard good things about NX and am thinking of going with them myself in the near future but need to decide how much of a shot I can run on a stock motor.

NX kits are good but expensive. The have a lifetime warranty on there solenoids as does Compucar and a few other companies. Check out Cold Fusion; there solenoids have massive orifices for there size. You can squeeze a way bigger shot out of the same size cold fusion solenoid than you can most any other brand. I can't really think of any brand that isn't good, you just get different types of warranty service, and slightly different designs with every brand.

NX spraybars are supposed to be a much better design than the nos kits. I am prob going to get the stage 6 kit. very adjustable

Where did you hear that that the NX spray bars are better? If it came from NX you might want to double check with some non biased people. I really dont know which kit is best as I have heard good things about every kit. I have the NOS kit on right now and have not had any problems with it whatsoever. It has always performed nicely. But I might switch to some others just to check them out since I am upgrading this winter.
