For this engines i look for max continous power at FTH, and for max power (w and w/o injection) ever at FTH, and the respective engine setting (rpm and pressure).
Only engine variants on WWII fighters.

R-2800-18 normal 1550 hp at 26000' at 2600 rpm, military 1800 hp at 23000' at 2800 rpm,
R-2800-10 rated at 2550 rpm (39'' Hg), all out 2700 rpm (52'' Hg) (british)
R-2800-10 normal 1550 hp at 22500' at 2550 rpm, military 1650 hp at 21000' (22500') at 2700 rpm (52.5'' Hg), water injection 1975 hp at 16900' (60'' Hg) (british climb/continous 44'' Hg/2550rpm, combat (5') 52.5''Hg/2700 rpm, combat with water 60'' Hg/2700 rpm)
R-2800-21 rated 1625 hp at 30000' at 2550 rpm (40'' hg) military 2000 hp at 27000' at 2700 rpm (52''Hg)
R-2800-63 water injection 2260 hp at 27500' at 2700 rpm (56'' hg) (2330 hp at 15000' same other but turbo) standard called 2300 hp at 27000'
Hg possible upped 65'' or 66'' with and w/o water injection in summer '44 or late
R-2800-57 normal 1835 hp at 25000' at 2600 rpm (42.5'' Hg), military 2225 hp at 25000' at 2800 rpm (53'' Hg), water injection 2800 rpm (72'' Hg) no table the plane crashed trouble for maintenance a this setting of power

from Tzaw1 pdf:
R-2800-21, -59, -63 continous 1450 hp at 13300' at 2400 rpm (43'' Hg)
R-2800-57, -77 continous 1600 hp at 16200' at 2600 rpm (45'' Hg)

take all with a grain of salt:
R-2800-8 and -10, basically same engine, normal (continous) 1550 hp at 2550 rpm (39'' Hg) at 21000'+, military 1650 hp at 2700 rpm (52.5'' Hg) at 21000'+, water injection (if available, w variants) 1975 hp at 2700 rpm (60'' Hg) at 16000'+
R-2800-21, -59, -63 basically same engine, normal (continous) 1625 hp at 2550 rpm (40'' Hg) at 25000'+, military 2000 hp at 2700 rpm (52'' Hg) at 25000'+, water injection (-59 and -63) 2300 hp at 2700 rpm (56'' Hg) at 27000'+, possibly boost later increased at 65'' or 66'' Hg
R-2800-18 normal (continous) 1550 hp at 2600 rpm (? Hg) at 26000'+, military 1800 hp at 2800 rpm (? Hg) at 23000'+, water injection data non available
R-2800-57 and 77, basically same engine, normal (continous) at 2600 rpm (42.5'' Hg), military at 2800 rpm (53'' Hg), water injection at 2800 rpm (72'' Hg) maybe reduced??

for non japanese speaking, like me, i add that kaisei it's mars and kinsei venus
Specially for non japanese speaking, like you: Zuisei is Comet, Hitachi Ten-pu - wind in the high sky, Kotobuki - auspicious, Hikari - Light, Sakae - glory, Mamori - guard, Homare - honour.
