Hey would it be cool to use a T3/T4 turbo + any high compresion pistons? I meen is there a certan boost level you cant exceed or is it just an all around stupid idea?

My frend is a certified mechanic, he seems to think it would be cool as long as you have TUFF ASS rings and you dont exceed like 14psi or something (his words "as long as you dont overdo it!")

Thanks for your input
