I have a stock '89 5-Speed, MSD, CIA, 68K Miles. I am wanting a boost, how much can a stock engine handle a 75 shot of nitrous? It goes in for 4.10 Gears soon but it wont be enough. Any thoughts from people who have really used it before? Or just work on a Heads and intake kit, or supercharge it even with stock heads and intake?! That would also include a adj fuel pressure regulator and it would be taken int an dyno tuned for it.
