420a turbo help

[turbod texas boy]

Okay so I recently bought a 1997 with a seized engine I want to pull the engine and replace it with a nother 420 a I want to run it with forged internals fuel injectors fuel pump me know better everything overstocked and I was just wondering what would a well built motor cold up to it boost wise I also want to run a 75 shot of nitrous what I'd be better off running just pissed with the higher PSI were slightly lower PSI with the 75 shot of nitrous it's going to be a daily driver that I like a stinker it take to the strip and the track I appreciate the help and thanks sorry if it's a little hard to understand I'm using the talk to text feature on my phone as my jackass friend broke my laptop

If you are going 75 shot for sure you need good internals. Depending on what you spend in the internals is how much boost you can run. I got decent internals but my safe setting is 25psi and i got no NOS

First of all this has been discussed a billion times.
A 420a with forget internals is in theory, only limited by the quality of the build, and the Ecu tune.
By just saying "what is the psi limit" when running turbo means very little without explaining which turbo is in question.
