Default F20B homework

i have an F20B motor and i've been reading a lot of the threads on this motor in the archives. i know there is not a lot of info out there on this motor and thought it would be helpful to show all the info i got. the majority of the info is for the manual cause if you have this motor, it's the one you should have. if i made any mistakes, feel free to make any corrections.


basically a destroked H22
identical blocks/different sleeves/different internals

the base motor for the F20C (S2000)

mugen needed a motor that was a maximum of 2.0 liters to compete in the japanese touring car class

in accord/troneo (CF4) (JDM)
SiR (automatic)
SiR-T (manual)
SiR = sport injected racing T = troneo

OBDII - open deck

200 ps/145 tq
200 hp @ 7200 rpm
145 lb-ft @ 6600 rpm
vtec @ 5500 rpm
redline @ 8200 rpm

11.0:1 compression ratio

type-s cams/valvetrain/porting

iron sleeves - can use forged internals

block = 85 mm bore/ 88 mm stroke = 1997cc

rod specs:
length: 145mm (5.709")
BE (big end) bore: 48mm (1.809")
BE (big end) width: 23.75mm (0.935")
