I heard something about port and polish on exhaust side is good for a turbo but on the intake side just port it so the fuel will optimize or something i have no clue if this is true can someone verify that.A Friend Of Mine Has A Eg Hatch He Has Fully Built D16z6 And His Next Plan Was To Turbo It But He Thinks He Cant Because He Has The Head Port And Polished I Told Him He Could Can You Guys Help My Friend
How you can qualify stage 1-2-3 port and polish ? Everyone has different mind and ideas on what is a stage 1 or stage 3. Is it only unshroud valves ? Matching manifold and gasket ? or massive grind of the intake and exhaust port ?Turbo it, he'll love it!!! I have stage 2 port polish head w/ t3/t4 turbo on a stock bottom end..
