im planning on building my z6 for boost. just wondering if i could run 12-15psi on stock valves?

 

it has been done. if you are upgrading other things like internals to accomodate the 12-15 psi you should be fine, stock valves are pretty tough


also its a noob thing but when you post psi you should also state what turbo you're running.... 15psi on a KO3 is a hell of a lot different than 15 psi on a HX35

 

i was thinking like a t3t4 or a someting its a d series. i think thats prolly as big as i could get, maybe just a t25. i dont know much about turbos yet, what would you suggest?
