How can I make my F20B faster?
To get even more power, you will have to buy an H22A head, and H22A headers and intake system. These mods will make your engine more powerful. If you want to get 250 horsepower with your F20B block + H22A head, then improve your engine according to the recommendations in THIS article.
How much HP can a F20B handle?
F20b won’t handle much boost due to the high compression. But if you want you could run 8psi safely. Treadstone makes a good kit, not eBay quailty, but it’s not the best quality. For up to 400hp it’s well enough.
How big is the intake valve on a Honda F20B?
For a cold engine, intake valves clearance is 0.24-0.28 mm, and exhaust valves clearance is 0.28-0.32 mm. For F20A and F20B3, the fuel injectors size is 240 cc.
What kind of engine does a Honda F20B have?
This kit ensures 2 liters displacement. For F20A and F20B3/F20B6, the 16-valve non-VTEC SOHC head is used. Honda Accord SiR and SiR-T F20B were fitted with DOHC VTEC head engines. The diameter of intake valves is 34 mm, of the exhaust valves – 29 mm.
How often does Honda Accord F20B need to be replaced?

Is the H22A engine interchangeable with the F20B?
