94 GT nitrous questions...

Put your timing on 8 or 9 degrees btdc. Go one step colder in spark plugs. The brand really doesn't matter, except that you want to stay away from platinum plugs. They don't mix well with nitrous from what I've heard. I've used Autolites and NGK for years and they've suited me fine. Gap the plugs around .035-.040. If you have an aftermarket iginition you can get away with .055 according to the NOS tech. line. I run a 150 shot (NOS 5115 dry kit) with my timing on 8 degrees btdc and a .055 plug gap. But I have a Crane HI-6 ignition. Since you'll only be running a 75-100 shot, I'd put the timing at 10. The rule of thumb is to retard your timing 2 degrees from where you normally run it, for every 50hp. of a shot of the juice. I'd put the 73mm MAM on for sure...but the 24lb. injectors will do nothing for you. You wouldn't need those unless you were running aftermarket heads/cam/intake. You don't even really need to get a bigger fuel pump with a 75-100 shot...although it couldn't hurt. Because if you want to go faster...and I'm sure you will...you'll need a bigger fuel pump for anything over a 100hp shot.
