I was looking at some old post, concerning the HP limitations of our motors with certain bolt ons. A professional tuner stated his cut off for the Precision (drop in) turbocharger is 420 HP for a stock long block with bolt ons.
The Precision turbo turbine housing is approximately 6% larger than the turbine housing of the turbo you have chosen. Based on exhaust back pressure alone... a safe limit for your set up is probably less than 400 HP.
The answer to your question is really based on your risk level and if you can afford a new motor.

Thank you very much for your time and knowledge, I had to postpone the project through winter, but I'll for sure learn a lot from your replies.
Thanks a lot!
