One of my mates who owns a speedshop maxported a A-series cylinderhead for me, the result was IN180hp EX110hp! He used 40mm intake and 32 exhaust valves and made a compromise between high gasspeed and airflow, the bottom of the intakeport was raised with epoxy but he managed those figures without welding. I havenīt tested the head yet so I donīt know how it works but he was very impressed by the numbers, especially the ratio between gasspeed/airflow! He uses a Superflow flowbench! I am dreaming about a +200hp N/A A-series engine in my rallysprint 1200!

The other 200HP A-series are not strokers, but are running high RPM (excess of 10,000 RPM) with highly modified heads with raised/fabricated ports.
