How is displacement is increased in F22c1?
Found this video on youtube, I'm sure lots of people on here have seen it
My question: Is the F22C1's added displacement achieved by how Ichishima-san described it? He says in the video that's how the stock 2.2Ls work too. But he never really outlines how the spoon engine is different?

F22C at it's 8200 redline has slower piston speed than the F20 at 9k. Basically they were safer when they made the f22. The point at which both max piston speeds are the same is around 8500, which is why some raise the redline to there. Some others are even more ballsy and raise to 9k, but I do not recommend this unless you have more engine work to reduce that mass. The rest of the engine can handle it, as it's better than the f20. There's a video out there discussing it with the honda engineers and tsuchiya, but I'm too lazy to find it .

No oil burning issues, no cracked retainers (and its a common upgrade for people to go from ap1 -> ap2 in their ap1 to stop cracking retainers, even though the cracking is caused by their bad driving. Still, ap2 valetrain is superior). The only thing the f20 has over f22 is RPM and lower displacement with same peak power. I never claimed as a whole the f22 is better than the f20c, I said the rest of the engine is better, which it is. Pick your poison when it comes to the overall package, the debate is endless.

F22c is not better than f20c....
