Another big difference was that the KA24DE had larger diameter inlet valves, better knock sensors, revised oil pickup, and a compressed ratio of 9.0:1 or 9.5:1. That means it had a higher redline (6900 rpm) compared to its 1988 predecessor (6500 rpm). Moreover, the KA24DE naturally aspirated engine could reach 155hp with its peak power at 5600 RPM.
