@fouadar - sir, great restoration work - I hope the 1UZ serves you well - it is a great engine!
One thing I would sincerely recommend - replace your airbox with a straight through pipe connected to a snorkel outside the vehicle (with necessary AFM plugged in) - your intake pipe is picking up heat from all over as well as your radiator as of now.
You will notice the engine perform much better, and for a longer duration with the above recommendation.
