I found this guy selling SC pulleys on another forum. It's .3 inch smaller in diameter and says he's seen 11psi. Don't you think it's too much boost? Also, is the Eaton SC a model M45 or M62 ?

Everything I've ever read that mentioned it said it was a 'customized for Nissan' M62. One of my friends has an S/C Frontier and his boost gauge has touched 9psi. Since 11 is really not a ton more, it's probably okay. Only time will tell for sure.

Two psi is a very big difference in the amount of air that can be forced into an engine. Once you change one thing, you have to go down the line to adapt the others to the change. These engines are computer controlled, when you change boost pressures the ECU needs to be remapped to add more fuel. More air without more fuel equals lean engine. That's bad. [Wave]

May need different injectors and/or fuel pressure regulator too. It's not as easy as just boling on a smaller pulley unless you want problems later on.
