I'm looking into getting a twin turbo setup. I would like to have between 500 and 600 horsepower at the wheels. I know there is a lot of custom setups out there but i don't know what to look for in a custom setup. I would like lightning quick spool up and a target peak boost of about 60 psi. I would appreciate any help with turbo selection, different exhaust housings, price, and where i can get them. Thanks for the help guys.
