I'd run headers then a 75 shot would be ok. Thats about the max I would run on a stock internal built engine as well. You would be pushing a 75 shot on manifolds.
You will have to run atleast one stage colder plugs, and start your plug gap at .035" and work your way up. Most cant go larger than .042" before they get misfires under boost and juice. I personally run mine at .035" and call it a day when spraying. I played around with the plug gap, and found out that size works best for me, but everyone's engine is different.
Build the engine to take it from the bottom up and you can run a much healthier shot, but there are still limitations to your madness.

The M90 loves nitrous
I'd start off with a 55 shot and tune for it. An AFC would be great if you have a wideband and no way to tune otherwise. Once you get it dailed in, up the shot and repeat. Do so intill your spraying what you'd like. I'd run NGK TR6's for small shot's and TR8's for large shots of spray. If you have not yet bought a bottle set up I'd strongly push to towards a zex wet kit. It has the best fool proof setup IMO.
My old 9:9:1 xpz'ed ic'ed motor was sprayed with 125 shot wet and it was a quick way to pick up some nice mph at the track. I sprayed mainly when I was running race gas because it allowed me to add timing with the spray. I never sprayed the car on pump gas on the street. It was pointless when the car would blow the tires off at 55 already.

thanks guy's this is my wife's gtp im workin on we have the his/hers combo. lol she just wants to break in the lower 13's were sitting at 13.88 now.we just figured nitrous cause she doesn't want a smaller pulley. she has an afc now and tr6's gapped at .32 runs pretty damn good for a 3.8 pulley car.
she doesn't like how my car drives she says, and she only races at the track anyway so i just like the fact she likes to mod cars as well.
they burn pretty pretty good no left over fuel! lol, i gapped them that low due to a miss at high rpms, when gapped @ factory .55 pulled the plugs re gapped them no miss and made almost .75 aof a second faster at the track.
she gets into the throttle a lot lol just to torquey for her dd i guess. thats what she wants to do so....
