I was wondering if the stock valvetrain could handle 15-19 lbs of boost or should i go aftermarket? Also if i go aftermarket what brand would be the best would you recommend? What cam I would use also or keep it stock?

Also, should i sleeve my block?

Thanks alot

its not about boost. its where the powers made and the rev limit. when getting a cam is the best time to upgrade even if u have a bigger turbo that needs those rpms. stock valves can handle anything u wanna throw at them. as for sleeves thats up to you some have made 400 on stock sleeves but you can always make more and be bulletproof. you need to specify power goals and setup.
