F22 with H22 or H23 tranny?

[Fearit22]

Well it was brought up on another board that the f22 tranny can be switched out with an h22 or h23 tranny. I was wondering though if there is any advantage to actually doing this? Obviously I know if it had an lsd it would help but is the tranny actually stronger and would the gear ratios help or hurt the f22?

Well the H23A transmission is one of the best acceleration upgrades you could do to your F22. The H23A tranmission is geared higher then both H22A and F22A. I'll try to due a side by side chart for you but it may be hard.

F22A H23A1 H22Ax

Diff: 4.06:1 4.27:1 4.266:1
1st: 3.31 3.31 3.307
2nd: 1.81 1.86 1.950
3rd: 1.23 1.32 1.360
4th: 0.90 1.03 1.034
5th: 0.71 0.81 0.787
Rev: 3.00 3.00 3.00

So it doesn't completly line up but you can see and compare. The H23A and H22A are geared pretty similar but the H22 is still higher. I run my H22A with an H23 transmission and I love it, makes the car feel super light, like the engine has no trouble pulling it. I can only imagine with the H22's. May not be very noticable but I will be running the car vs. an H22 Prelude on the weekend so we'll see if I really suffer. If I do it will be in second gear. Hopefully I'll have the power to make up for it. Top end does suffer at 80mph I am just under 4K rpm on my tach which is more realisticly about 3600-3700 rpm.

The H23A's main advantage over the F22 is the final drive. Some gears are very close or even the same but the final drive makes all the difference. Either way both H22A and H23A tranmissions would be an improvement but the H23A would be easier on your gas dollar.

Well you said you aren't sure but I was really wondering if the h22 or h23 tranny is stronger because I plan on turboing the f22 and I don't know how well the tranny will hold up. So basically with that gearing I would notice better acceleration? I don't need my top end right now anyway since the governor owns me at 115.

Either tranny even your F22 will hold a turbo charged F22. In fact why not leave your F22 transmission if you go turbo, you should have enough power to compensate. If you get all this power and are geared to high then you'll top out before the end of the track. That probably won't happen but I'm just saying consider just keeping your transmission.

I know several H22A Lude owners that have turbo/built H22's that actually go use the F22A1's transmission and just add an aftermarket LSD to it.

Alright thanks for the input. I would really like to get an lsd but that's a lot of money. I probably will once I actually go turbo, but until then I'll leave long one wheel marks.

The F and H series transmissions are all built the same, just with different gear ratios. I wouldn't worry about breaking anything. What would be neat to do if your are going to add an LSD, is to do custom gear ratios. Like 1st-4th from an H22, and 5th from an F22. That way you get the acceleration of the H22 tranny, but nobody ever even USES 5th in a 1/4 right? So th Accord 5th will let you have a lower cruising engine speed while on the freeway.

Hmmm.. I don't think so, as shot peening and such would damage the bearing surface of the gears. I suppose it all depends on what the weak points are. The shaft may be it , or the gears may be...

Check out HS. There's this guy on there that goes by "boostedaccord". He spent a hell of allot of money turboing his F22B1 only to strip it, H22 it, got stolen, now he still has all this stuff.

Anyhow the point is he had something done to his transmission called cryo treatment or something. It's super expensive and is supposed to strengthen the transmission consiberably. There are some posts where he is talking about it.

There's also some others where he is selling the transmission with a CM stage 4 and flywheel for like $1K or something. He's reduced it by almost $1K. Supposibly that work is really expensive. Check it out maybe your answer is that.

so if you have a lightly modded non turbo F22 what trany do you want?
then once you have a H22 non turbo what tranny do you want?

[4drcord]

oh i thought that turboing would play a major factor in this but i guess not?

[4drcord]

thx thats exactly what i was looking for.

How about H22a accord with f22 transmission and smaller diameter wheels and tires?

[blazen_accord]

CAn an LSD be used on an automatic F22A tranny?? sorry don't have 5 speed. if yes where can I buy one, my driver side tires spin and pull to the right when I floor from a stop?? but take off straight when drive normal??

just som FYI
Deep cryogenic tempering is a one-time, homogenous process that permanently and dramatically improves the performance and useful life of metals in everything from brake rotors and performance engines to machine tools and gun barrels. Using a proprietary computer-controlled process, the metal is cooled slowly to deep cryogenic temperatures (-300°), and slowly returned to room temperature, then heat-tempered as the final step. Computer technology allows us to regulate temperatures to 1 degree, accurately controlling Cryo tempering in accordance with the material and mass of your parts. Although not apparent to the naked eye, the improvements to the metal are significant. Deep cryogenic tempering creates dramatic increases in abrasive wear resistance and durability. The increases in tensile strength, toughness and stability couple with the release of internal residual stresses.
so yeh.. it can come in handy to cryo treat.. lol
but still expensive .. its a "cheap insurance" although its not cheap lol
by the way a hybrid h22/f22 tranny would kick ass.. can this actually be done without major modification without just swapping out the gears?

[Fearit22]

Well it seems they are a pretty close fit. It shouldn't be anything too difficult. If you are going to be making a lot of power the f22 might be the way to go because you are going to have to shift a lot more often going down the quarter mile if you have an h22 tranny. After a certain point you would actually pull better times with the f22 tranny.
