I wouldn't do that if I were you. Especially considering the fact that the internals are stock and you have had issues with proper tuning as is without nitrous.

Agreed. If you want to spray with boost, you're going to need something tunable, and forged internals.

agreed, you asking for trouble as it is boosting with nothing but that shitty atempt at fuel management, adding for nitrous would be the equivalent of driving the car with no oil, you WILL blow it to peices as it sits now, and if you dont know what your doing, you WILL blow it to peices with a built motor

my computer is tuned what else will i need to be tuned i want to use my zex kit just a 50 shot also the problem i had was the spark plug those shity platinum 4 i have ngk6s now

You should be running a 7 series heat range plug. The 6's are too hot for turbo and definitely waaaayyyy too hot for turbo and nitrous. You are going to need forged internals if you plan on using the nitrous. And if you did that, it would be less of a hassle to use a larger turbo to make more power instead of adding another tuning variable.

Your computer is tuned? What kind of engine management are you running? If you just have an FPR and 450's your computer isn't "tuned." You need to offer up information like this before we can give you answers.
