For those of you that have it, or no about it.....
My question is this: What spark plugs did you use? I know they need to NOT be platinum and be a degree or two colder? Anyone give me info on what i should buy and from where? LukeGSI 
Second question....whats involved with forged pistons...i think im gonna go do this...whats it all about....how much am i looking at?
Third and final question....running a higher octane fuel with the nitrous...what happens if its run with normal fuel?
Thanks for your help....all the questions are for a corsa C.
Bye

material of plug should make no difference. and they dont really measure them in degree's
forged piston as they sound are forged, not sure for the corsa but for the micra your looking at £600+ for forged pistons.
nitrous will run fine with normal unleaded

ok from nitrous.info:
Fit a new set of COLDER plugs. For example if your stock plugs are NGK-B7HS, for example, then use NGK-B8HS or 9 even, instead. This is one to two grades cooler. They need to be gapped about 10 to 20 percent less than stock plug gaps were originally. This has no "noticeable" effect on power, but means that when the Nitrous is operated, the standard ignition system can still cope with the higher effective compression ratio and still spark. Also if your plugs are "projected nose" type, fit NON projected nose ones! Ideally you want the shortest electrodes you can have! Imagine playing a blowtorch on your plugs. Which bit will glow first? Answer - the bottom earth electrode! Go for shorter ones... Use standard NGK plugs if possible. Avoid fancy expensive platinum, or multi electrode types.
Just wondering on that question where from and how much  oh and which ones 
The high octane i think is needed to protect the engine from detonation.
But if people that have Nitorus in there cars can help with the above...id be thankful

I would want to use super with n2o for a extra bit of safety.
Why have you decided on forged pistons if you dont know what they are about?
The are stronger, you can get off the shelf higher compression ones, but if you want lower compression ones they would need to be custom made.
They are a straight swap for standard pistons, cost from about £360.
