Could the Mitsubishi A6M8 been adapted to be powered by the Nakajima Homare 11 engine instead of the Mitsubishi Kinsei? As I understand it, the Homare engine was an 18 cylinder version of the 14 cylinder Sakae engine, of course boosted to run at 2900 rpm instead of 2750 rpm.
The Sakae 21 used in the A6M3 was 1630mm long by 1150mm wide and weighed 590 kilos. Power was 1130hp@2750rpm for take off. 980hp @ 6000m @ 2750 rpm
The A6M8 used the Mitsubishi Kinsei
The Kinsei engine was 1660mm long and 1218 wide with a weight of 675 kilograms. Power was 1560hp@2600rpm for take off; 1350hp@2000m@2600rpm and 1250hp@5800m@2600rpm
My alternative A6M8 uses the Nakajima Homare 11 engine
The Homare engine was 1690mm long by 1180mm wide with a weight of 830 kilos. Power was 1800hp @ 2900 rpm for take off and 1460hp at 5700m at 2900 rpm.
Anyway, for an engine the same size as the Kinsei, they get an additional 200hp at altitude for the cost of an additional 155 kilograms in weight. Besides the problem of mating this wonderful "new" engine to the old A6M airframe would such a substitution make any sense for the Japanese to have done in say 1943-44?
