non turbo. stock piston length and would prefer standard pin size/height. port and polished head and intake. nice gouge in cylinder wall all the way out to 76.85mm but 77mm will work to and why not. not much left on the walls after that anyway. dont NEED turbo pistons but would consider it for future running times and conditions, but for now trying to keep it as stock in engine bay as possible. fan of the a series. what can i say
