f22b

[ti's 92 accord]

true. i dont mean to argue with you but the dohc vtec is like a bored out dohc non vtec. v tec was ment as a gas saver and gives like 10 to 20 more hp?
if honda wanted speed the would have just bored out the nsx engine. but they also wanted to save gas. so the gained the gas miles by adding vtec but lost hp by not boring out a dohc.
once again sorry i have done my research on alot of things....and i may not be certified yet but thats because im to young to be certified haha..

boring out a dohc 2.2 will give more power than a vtec 2.2.

[deevergote]

Boring out the engine has nothing to do with the valvetrain. Your argument makes no sense.

I'm not looking to pick a fight... just discussing... I'd like to see you explain your position in a way I can understand. So far, I don't.


VTEC is used to increase the powerband throughout the RPM range. The H22, .1L less displacement than the H23, makes 40hp more. Why? VTEC.


Your argument is rather archaic... saying that displacement is better than anything. How much do you really think you can bore out a small Honda 4 cylinder? Why doesn't the 2.3L H23 make more power than the 2.2L H22? Or even come close to it? The torque difference is only 2lb-ft.


What grounds do you have for your claim? What research have you done that says VTEC is for fuel economy only?

[ti's 92 accord]

the h23 has a smaller valve train.

i have talked to 3 or 4 honda techs in the nashua and manchester area and they have all said it was just a gas saver i have read threads on the internet explaining that vtec was a gas saver.....i cant find the sight. but if they are wrong than i am wrong and im sorry. and i also will look like a complete tool if im wrong...so im just going by what i have read and what these guys have told me because i got into an arguement saying the same exact things you are saying to me. but i could be wrong those honda techs could not no what vtec really is. so if they are wrong than im a complete idiot

[deevergote]

Honda techs or not, they're wrong. Doesn't mean you're an idiot... it just means you need to validate your information, and not just take the word of others.

Numbers provide results. The H22 makes more power than the H23. Significantly more. The extra displacement provides slightly more torque, but the horsepower of the H22 is considerably greater (due to the improved high-RPM breathing... the only way to make power with a small displacement engine).

The size of the H23's valvetrain is irrelevant.



SOHC VTEC is basically a gas-saving design... it's also a sales gimmick. That VTEC setup is for the intake valves only, and doesn't work the same as the DOHC VTEC. Your argument is much better suited to those motors... and in that case, you're partially right. And totally right in the fact that they're inferior to the H23. Motors like the H22A and DOHC F20B have more to offer than the H23 and F22B, though.


Some people will argue this. The H23 powered Preludes have been known to be nearly as fast down the quarter mile as the H22 powered ones. Some people just don't want to hop on the VTEC bandwagon, and that's their preference.

Honestly, if I were to stay non-vtec, I'd do it with an F22A head. Bisimoto's research and accomplishments with that head are enough proof to me of their potential.

[ti's 92 accord]

would i get more power by tuning a f22b dohc or the f22a sohc

[deevergote]

It depends on what you do. I don't know many people that have explored the full potential of the F22B, but I know of 3 F22As in various stages of tune... one is making over 150whp (the H23 would make about 130... stock F22A makes between 105-120), another is expected to make 240-250whp (waiting on the header to dyno tune it), and one is making over 400hp (to the crank... that's Bisimoto's race engine)

Deeve another thing you have to consider about this swap and any other non vtec swap is people don't always have the money to pay for the premium gas needed with all vtec engines its an added cost not alot of people can afford now or ever due to the high price of gas already. I would be getting an h22 if I had more money but I don't and I don't have the flexabilty right now to have a car that needs premium gasoline hopefully in the future I can do a h22 build but until then I will enjoy having an extra 20hp out of the box and going back to a dohc set up.

[Dani Filth]

no money for gas is all good but that doesnt make vtec worse than nonvtec. the other guys argument that it saves gas would mean that vtec is better. the h22 only takes more gas because it has higher compression not because its vtec. deevs argument had nothing to do with cost

[DA92CB7]

maybe so but he was implying that the f22b is not a good idea for a swap in a cost effective perspective, but some people just want to do something different thats really all I am saying.

[deevergote]

$800 for an F22B or $1000 for an H22A. If 20 more horsepower is worth $800, that extra 40hp should be worth the extra $200.

You have a point about the gas, though. At about $.20 difference between 87 and 93 here in NJ, I hate filling up with 93! Of course, when you think about it, it's only a difference of $3 max... So I eat one less Whopper each week.

[DA92CB7]

well I will be getting my f22b for 650 I guess I should have paid more attention to what you were pricing the motor at if I had 1200 I would get an h22 auto swap but I dont so I will get my f22b and be happy with that and hopefully an h22 auto trannie as well.

[ti's 92 accord]

i also like the f22b better because falot of people have the h22. so i can tune the f22b to smoke a tuned p h22 i will be very please.
when i get the f22b im going to get a new camshaft, cams, the h23 intake and bore that out a little, pistons, fuel rail, injectors, fuel flilter, fuel pump, turbo, nasty blow off valve and waste gate, new clutch, valve springs, probably bore those out a little too, 5+ spark plugs, msd ignition. thats what i have been saving to do. if you guys have any other ideas let me kno. thanks

I have a great idea. Learn more about what you want to do! I can see at least two inconsistencies in your plans... and at least two statements that suggest you don't know a thing about what you're talking about.

Pick up a book called "Honda/Acura Engine Performance" by Mike Kojima. Read it. Twice. You'll know all you need to know to make an educated decision when planning out your performance plans.
