The Vortech A-trim kits are good up to 450hp and safely operated to 10psi of boost.
I have seen them very cheap(around $1850) you can start with a 6lbs pulley then work your way up to the 8-9lbs pulley later on.
You'll be able to reach 300hp EASY!
The only thing I'm not sure of is,the California emissions testing.
