Nitrous? How much giggle juice?

[Swan song]

ive got a bone stock ‘93 ls400 1uzfe. I’ve got exhaust and intake on it. It’s in my celica. I wanna skip the build stuff and go straight to nitrous for drags. What’s the “safe amount” I’d like to not blow the engine up as it is a real pain to remove. (Worse than when it was in the Lexus...)

You've got the better, thicker rods in your motor so you should be OK with a 100 shot. Any higher and you're playing with fire. If you blow it up, stay with the early engines before '96. Lexus "upgraded" to thinner rods then.
