Default HP rating stock 1uz auto trans?

Im curious to know what this tranny can take? dont give me anything conservative. I plan on swapping the whole thing out and Im fine with blowing it up. I plan on until I swap the motor using the completely stock power and drivetrain. I want to put a 200-250 wet shot of nitrous for a few glory passes at the track.
Thank you in advance .

I dont think it will hold for a full shot at that much given. I have heard that people can do 100 or 150, but NOT 200-250. This is with the dragon torque converter also. With that being said, it wont last long with this mod also.. Dont know completely stock?

the tranny is only good for maybe 400lbs of torque. Its not necessarily the amount of HP, its the Torque that will kill you

just remember to increase line pressure for the trans so it shifts quicker - thus helping to reduce heat and maybe last a tad bit longer. lol.

Don't forget about the glass rods in the 1uzfe Lol
Also don't forget to swap in a walbro 255 fuel pump if you are going to run that big of a shot as you will for sure go lean on the stock fuel pump with that big of a shot.
