im planning to go h22 turbo. should i stick with the h22 tranny or use the f22 tranny? reason for using the f22 tranny is because of the longer gear ratio for longer revs for boost without shifting. some opinions and experience is greatlyappreciated.

 

I don't know about the h22 tranny, but I can hit around 65 in 2nd with the f22 tranny - probably be fun with some good boost behind it. Friends with Si and Type R are shifting into 4th as they come across the 1/4 mile.

 

In my opinion, you would want taller gearing for a turbo application so you stay in the boost range longer, therefor I'd use the f22 tranny. Plus, I much prefer the cruising 5th gear of the f22 tranny instead of reving around 4000 rpm at 70 on the interestate with the h22 tranny. For all motor, defintly the h22 tranny with the shorter gearing.

 

f22 tranny, you don't need alot of gear when running forced induction.

 

f22 tranny = longer gear ratio = more boost time = fun

 

which tranny is stronger i heard the f22 tranny will break!!!!!!!???????

 

although the f22 tranny has taller gearing meaning that it's good for turbo apps, the transmission is weak. consider using the 4th ggen prelude SI transmission. m2s4 is the code. tall gearing similar to the f22.

 

try a accord wagon or h23a tranny, they are inbetween the h22/f22 gear ratios.

 

it's not as weak as you think . . . my turbocharged accord with f22b2 (275hp)everything lasted through at least 70 hard track launches and daily driving before i took the turbo kit off of my car . . . you will need a limited slip that's all phantom grip or something

 

Its not any stronger or weaker than an H series tranny generally speaking, H series trannies have beefier syncro's, but the shafts, gears, forks etc are of equal strength.

 

ok what i learned=
long gearing = longer strain on the gear your in
shorter gear less strain

the longer the strain a greater chance of the gear breaking

 

Can you explain what u mean alittle better? You are using terms that are too general and nonspecific such as "gear breaking" and "strain" From what I could deduce from what you said you are incorrect.

The power going through the gear has the biggest impact along with the build quality of the transmission (materials & design) on whether or not it will "break" or not. Not how long the gear ratio is

 

in any gear if you lets say have 500 hp the strain on the gear it self 1 2 3 4 5.
the gear is not made to handle that amount of stress but the shorter the strain the less likely for it to break

like if the f22a trany gears are longer than a h22a then the strain on the f22a tranny will be greater because it takes long to go through the grears than if you had a h22a tranny which 1st to 2 or 2nd to 3rd is shorter between grears

hope this helps if not then let me know but i am not a pro so i could be wrong but common sence is saying if you pull on a fishing line with 6 lbs of presure for 5 sec. then pull on the same string for 10 sec. and it's is rated at 3 lbs it is most likely to break on the 10 sec pull right but like i said i could be wrong

 

Let me get this straight.The sohc f22 tranny's fit onto prelude h22 motors?Can you guess im a new-b.

 

yes, the h23, f23, h22, and f22 trannys are all compatible with eachother

 

f22 for sure= more gear= more time in boost= more fun.

 

has anyone try useing the h22 and the f22 tranny on a bosst h22? i been wondering about which tranny to use to. i had ask this question in the fI section and they had told me to stick with the h22 tranny. f22 have longer gear and will hold boost longer but with the h22 you will acclerate faster. not sure how that would work out.

 

I thought this was an old thread...
I just bought an F22 tranny and I just ordered my H22A. I plan on boosting down the road so this is why I chose this setup. When they say longer gearing you will be in boost longer they mean the following (generally). When your engine has longer gearing you will be revving the engine higher for longer. The higher revving will produce more boost. When you are in boost you are producing much more power than you are at lower RPMs or lower boost levels. When you stay in maximum boost level you are making the most power. Basically more power longer. In shorter gearing of the H22A tranny, you will build boost, then shift, build boost again, shift again. In other words you will be starting back to the NA power level and building power back up as boost goes up instead of steadily staying at a high power level to accelerate in each gear. Not to mention the higher cruising RPM at highway speed.

 

i ran boost on my f23 and the tranny ran fine and had no prob. i would go with the f23 tranny

 

If this is a track car... 1/4 mile queen... auto-x... etc... I would say h22 tranny.

If this is a daily driver... street car... highway hotrod... etc... I would say the h23/ f22 or something like that.

Otherwise I am going by what I said in previous post.

I've heard alot of people with different suggestions.... I have a post about a 90 accord engine swap... I have been considering some of the same things you are and according to a Honda professional who is the only person that has ever touched my car since I got it b/c he comes so highly reccomended by everybody around here. He has told me that I definetley need to go with either the H22 or H23 tranny. Now I'm not saying he is definetley right but he did say that if i was to leave the stock f22 tranny that i have now i would eventually have to keep rebuilding it or do something b/c the stress on the tranny would be to much in the long run. He did however say that my times would be a little quicker but in the long run or short run according to him it would definetley not be worth it. But I would ask some more and see what you come up with. I hope I helped you a little. If you have any info. about this swap I have a post up in the tech forum and I would really like some help and ideas. Race On!

 

just wondering do they make a lsd for the f22 tranny? and does it matter which model and year accord it comes from?

 

The fifth gen F22 and H22 trannies are the same except for the gearing.

Any LSD for a prelude app will fit in an accord.

I have a quife. The part number for the prelude is the same.

Everyone one is wanting an H22 in there Accords, I know its easy way to make power and all but im gonna stick at the bottom of the barrel and boost the non Vtec single cam like niedejb is doing on his F22B1. With a little help from Accord94Dx it may be here sooner than i thought. Ive got nothing against an H22 in a Accord, afterall it is stock in the land of the rising sun.

 

f22b1 is sohc vtec... your thinking b2.
