I am building my first z6 motor for turbo. I am looking for 400 hp. As of now I only have a sleeved block with 76mm bore. I also have a low milege stock head. My first task is to get the correct pistons and rods. I was thinking of getting vitaras (76mm) pistons. What rings would I use. Also, should I get eagle h-beam rods or are there other good quality rods that do not require notching and that I can safely use at 400 hp. I want to build it right the first time.
