h22 tranny vs. f22 tranny

[cloudasc]

Thanks for the clarification, lots of great knowledge, its what keeps me going through these posts. Theres more of a difference between the f22 and h22 transmissions other then the final gear, right, the rest of the gears aren't the same either? If so then most of what I said was true, its a difference in gear ratios, and in your case the final gear ratio, so to save gas mileage in your case, you could swap in a f22 tranny to try and save gas mileage, but if you wanted to keep the acceleration of the h22, saving gas by taking less time to acccelerate, and still be able to save gas at your cruising speed, change the final gear ratio, to what works for your application. I'm pretty sure there are lots of people here to help you figure the final ratio to match the power band of your motor.

Remember the old 60-70s muscle cars? They only had 3 speed manual transmissions, that could take them up to 160+mph. An example of this would be my dads 63 Plymoth Fury Golden Commando Edition (highway interceptor package, a pain in the ass to drive around town, but geared to haul ass at 60mph+) 2+ton 19ft long, enough trunk space to stick 4 dead bodies, with a 3 seat couch in the back seat. lol

so what you guys are saying. if i have a h22 + f22 tranny, i can have the acceleration-a little bit bc of the gearing of a h22, plus the fuel economy of a f22 at highway speeds (i.e. 85-95). tell me if i am understanding this correctly. like regular acceleration will be slower using the same amount of gas, but saying i use a certain amount of gas to accelerate in a f22, i will accel. slower in a h22+f22 tranny using that same amount of gas. but if i race i still get the h22 power at will.

Your post is confusing.

If you do H22 tranny, then you will get slightly quicker acceleration yes.

If you use the F22 tranny, then you will get slightly better mileage.

If you were to do the H22 tranny with an Accord 5th gear, then you would get a little bit of both.

If you change the axle ratio, you get something different still.

It kind of depends what you want.

Personally, the extra response of the H22 tranny makes the 2-3 MPG penalty worth it IMO.

It was designed to work with the engine and it does.

ya i kno that post was a little but confusing, but i didnt know how to word it. i think i got the advantages and disadvantages on having the H22 + F22 tranny. thanks for all the replies

btw just took a look at ur ride owequitit. clean lookin cb7. i like the black housed lights

LOL!

Thanks. It looks a little different now, depending on which pictures you looked at.

The H22 with the F22 transmission will accelerate more slowly, due to the longer gearing. At highway speeds, you will be at a lower RPM, however... which will save gas. The downside, other than acceleration, is that you'll often shift out of VTEC when upshifting at redline. That will hurt overall acceleration as well.

The H22 with the H22 transmission will accelerate faster due to the shorter gears, but you'll be revving high at 70mph. Not so good for gas mileage (not terrible, though...) Shifting properly with the H22 transmission will put you right back into your powerband.



The H22 will still make the same amount of power. However, as owequitit explained about the gear ratios, the power will be transferred differently. The F22 transmission is not optimal for the H22 in terms of performance. Still, it's not terrible, and it's fine to use when you want to swap on a budget.

my buddy has an h22 w/ h22 tranny when we race i think the only reason hes faster is the tranny but if u go f22 tranny like i got you will have the longest third gear u'll ever feel imagine doin like 120 just in 3rd

just get a h23 tranny...best of both worlds

What I have even though I think the m2b4 5th gear is broader than the h23. Ill have to recheck the gearing differences.

[deevergote]

In the 1/4 mile, the F22 and H22 transmissions are quite close... mainly because the longer gearing of the F22 transmission means you can shift one less time. The H22 trans will be faster off the line, but an otherwise equal car would catch up by the end of the race. The longer gears are best for turbo, I'm told.

IMO, the H22 trans with the H22 engine is the perfect macth (duh... Honda engineers aren't stupid!)

I respectfully disagree with part of what you say. The final drive of 4.226 for the H22 owns the 4.06 of the F22. Not only will you get to 4th sooner, but you will land 4th in a higher RPM. 4th gear is .903 on F22 and 1.034 for the H22. Because F22 4th gear is less than 1 I believe that makes it an overdrive. Overdrive is not good in a race because your gearing puts additional load on acceleration. Overdrive makes your car seem heavier to the engine.

But you know, if you are finishing your 1/4 mile in 3rd anyway this doesn't matter, and the F22 tranny would be advantageous for the reasons you stated.

When I had the F trans I finished the quarter in 4th but I had to shift out of it for the last few feet.

If you have enough power to overcome the gearing disadvantage, it doesn't matter.

Most people on here who have actually run both on the same car, ended up with pretty much identical times, because the extra time required to shift into 4th on the H22, offset the F22 tranny's acceleration disadvantage.

Having driven and felt both, the H is more responsive, but the F is still pretty close.

ive had f22, h23(current) and h22 tranny's and i agree with owequitit

cripe! what was your trap speed? I never even got to 4th in my accord.
My setup is F22 now.

I have an OBX LSD not installed. I am trying to conclude if I want to put it in a 94EX accord, JDM F22B, or H23 tranny.. Sounds like real work experience says it doesn't really matter... Only issue if I had a kick ass F22 motor mated to an H22 tranny I might run out of 5th gear before the traps. Those only go up to like 105-110 with the F22 redline?
