Don't wanna get to too involved & hijack yer thread pete.

Nitrous motors need a wide LSA , also a higher lift/longer duration to EX valve.

Tight LSAs are not good with nitrous run motors.

If it were me , i would go with a two stage fogger.

Remember that a fogger system needs a lot more setting up than a plate system.
If you have a two stage that's a bucket full of jets to play with and fuel pressure is a lot more sensitive.
Most foggers are set up on a dyno.
for a small shot and remember the recommendation is a max nos addition of 50% of your gas only HP and as you can achieve 400 hp shot on a plate then the plate is the way to go.

This is only my opinion , but if you're 'starting out' (like me) then the plate is the way to go , easier tuning with two/four/six jets as opposed to 16 , also being able to get the plug reading down to a fine art , which is easier said than done.

Problem with the plate system (cheater) is the bars spray @ a 30* angle , now depending which way round you fit it (fuel fitting to the front me thinks) it will have a tendancy to lean out two cylinders immediatley around the fuel fitting/jet side , the only way round this is to pull timing on those two cylinders , if you're ignition set up does'nt cater for this , then a colder plug in those two cylinders may help (helped on my setup).

The fogger is a safer bet , as you can tailor the tune for each cylinder , also pull or add spark advance for each cylinder , i'm hoping the NX plate won't suffer any distributing problems.

BTW , this is my experiance with the cheater plate , i'm sure others have had no problems.
