I have a 1994 svt mustang cobra 5.0 with stock internals and want to know what would be a safe boost to run if I was looking to turbo or supercharge it?

Alright guys, im new on the forums and i have found a lot of useful information on my mustang here. I have done light modding, but now im wanting to add something with a little more kick so i was wondering if the 3.8L stock internals can handle a small shot of nitrous.
