This is not really for my knowledge. A guy I know online wants to know the differences between the F22 and H22, cuz he said that they were the same engine, and I was telling him that size doesn't mean they are the same. Thank you.

 

f22-mainly in the accords and it's a single overhead cam engine. H22- in usdm prelude, A VTEC motor and it's a Dual overhead cam engine. and they are not same.

 

I know basics... I'm talking more deeply. Like the differences between the B18C1 and B18B1, but with the 2.2 liters

Final Drive: 4.06

II: 1.81

My F22a1 prelude doesnt have an oil cooler or knock sensor so ignition timing is static. Theres also no oil squirters and the camshaft has very little lift, fuel cut off is at about 7000 rpm. SOHC but 16 valve and 8.8:1 compression ratio. Basically this engine is all about getting the best reliability and mileage. This motor is just begging to be boosted.
