H22 with H23 5spd?
I'm looking to buy an H22 for a swap in my 4th gen Si 5spd, but money is tight right now. I've been reading these forums for a couple weeks now before registering, just browsing for information. I'm considering not buying a complete swap and just using my tranny from the Si. Since all the numbers I seem to find when reading and even searching the FAQS for the differences in transmissions, I've found that they all deal with 4th gen H22, 5th gen, ATR, Euro R, JDM S - can someone point me in the direction or advise me in the possible disadvantages of using my current Si transmission? (Or is it just assumed that the 4th gen H22 shared the same transmission, down to exact ratio's, with the H23?) Appreciate informative responses.

second post has gear ratios.

AFAIK the problem with using the h23 tranny in an h22 is that the gearing is longer, and shifting at redline won't land you in vtec for some gears.

simple fix = vafc = lower vtec X-over

If you do the swap go ahead and use the H22 tranny. It is gear different from the H23 and is better. More Powerful so to speak. longer gears. hmotorsonline.com has H22 complete swaps for only $1950. thats where i got mine. It has been great. good luck

yeah, but i don't like the idea of changing the xover for the tranny's sake. I'd rather x-over for the sake of the hp/tq curve.

The gears are shorter in an H22

Same here. I don't understand. I even saw a video of a guy with an H22 engine mated to an H23 tranny and he didn't fall out of VTEC. His 2nd gear went to about 65mph at redline.

They go hand in hand
Usually the Xover is at like 5200 which is really high for any prelude transmission. I had an H22 with M2S4 (si tranny see sig too) and I tuned it and dropped the Xover to ~4700 and it was no longer an issue. better power/ torque curves as well as over all delivery through the Si tranny on the track. On the street I kicked it back up to 5K so that I could get on it and not hit vtec. Besides if you are not racing all the time then it might be nice to spin 500 rpm slower at highway speeds with the Si tranny. 4K at 80 sux...

Re: H22 with H23 5spd? (fenominal)
I'm putting together another Prelude VTEC right now and all I could find was an H23 tranny, so what I've done is lighten the stock flywheel from 19-20 down to 12 pounds...hopefully that will help acceleration and reduce the effect of the longer gearing.

Re: H22 with H23 5spd? (ludeR917)
I know the ratio is something to something. It's the number of teeth the gear(1,2,3,4,5) has compared to something else... someone chime in about what that something else is.

Re: H22 with H23 5spd? (Kal)
it's the ratio of gear turns to engine turns
so a 3.307 1st spins 1/3.307 times for every 1 rpms then it's reduced by 4.266 times in the final drive to the wheels.
the end result...an h22a 4th gen in first gear at 7500rpms is going 7500/3.307/4.266 = 31897 revs per hour
circumference of a stock wheel = 23.9"*3.1415 = 75.08185" = 6.25682083 feet = 0.0011850039450758 miles
0.0011850039450758 miles * 31897 rphour = 37.80mph

Re: H22 with H23 5spd? (satan_srv)
I'm using an h23 tranny and I fall out of VTEC when I shift into second gear... Ive counteracted it by just feathering the clutch into second so that i stay above 5k, which sucks... I'm just going to lower the vtec point when I get my motor tuned to fix the problem...

that's gotta be killing your clutch

how would that reduce the effect of longer gearing?

Indeed, but it is only when I am racing, and it is definitely better that falling out of vtec... And in a month I should have my car tuned and just lower the vtec to 47 or wherever is best on the dyno....

It will rev up faster, but you have to remember it will also rev down a lot faster, you better be a quick shift mcgraw....
