I port and the manifold and close the unneeded holes and prespool ports .Reshape the turbo hot sides ,add a bigger wastegate door and port it. Fix the center section so the wastegate opens correctly .ect ect .The unit will flow better and spool faster . The work takes 15 -20 hours and uses mote than 1-1/4 lbs of welding rod .That is why I call it my Rich Mans Non Seq . Non of my customers have complained about performance .
