I'm planning to do the same on my 300C, how much rwhp you think you'll be making? I'm leaning toward the SRT8 killer option as well but I'm a little worried about the tranny holding up. Did you get the 6psi or the 8 boost? Thanks for all info, I'll be hunting for the STi WRX chump down the street that thinks he's hot S**T :nutkick: :biggrin:JonW said:
