If I am correct than the following things that i say must make sense. H22a red lines at 7200 and F22b redlines at 6500. 97 accords tachometer red lines from 6500 to 8000. SO If i swap H22a into my accord, my tachometer would be useless? Inaccurate? Will I have to get an aftermarket tach to work correctly with H22? any input?
Second question... Does anybody have or know somebody who had swapped H22a into accord AND kept his old f22b2 tranny? What are the pros and cons? Did they loose a lot of power offered by the JDM h22?
Some dyno results of H22a powered accord with h22 and F22 tranny would help!

 

you can retain your old tach......itll just be showing readline when your really not to redline yet.......you can always just get a new gauge face from a prelude and throw that in there.........keeping the old fseries tranny is a idea......bot the b1 and the b2 use the same gear ratios, and they are not designed for the higher reving h22........w/ an f series tranny, when you rev up the engine to vtec and beyond, and then you shift into the next gear, the gear ratios will take you out of vtec. in other words, they are too long and will end up making the car slower

 

Does anyone have the side by side gear ratio comparasin of F22 VS H22. I heard that 1st , 2nd and reverse gears are exactly the same ratios. Is it true? Also.... having longer gears on H22 with F22 will defenetly go into advantge with turbo applications. Question is.... how much will your stock f22 handle?

 

let me repharse it.... cuz it's confusing even to me... I was referring to H22a engine with F22 Tranny. And gear rations between H22 tranny VS F22 tranny.

well, the oem tach will work...it does become a little inaccurate, though, at 6000 rpm's plus....but it's usable...there are few alternatives...one is to use a vafc or similar system with a digital readout of rpm's directly from the ecu...another is to look for the 5th gen jdm accord si-r cluster on ebay...or you could retrofit a prelude cluster into your original cluster area...but this method requires lots of wiring...

i am currently running an f22 tranny on my h22a...it's not that bad, but i will admit that an h22 tranny would help acceleration...i am currently running 15 flat with my setup (last time i was at the track)...an h22 tranny would considerably help my 1/4 mile times, though...

also, as for your dyno results, they should be the exact same as an h22 with h22 tranny...power output would not change b/c of the h or f tranny...

actually, the h22 and f22 use nearly identical parts...yes, the two are geared slightly different, but both are constructed the exact same, using the same types of metal, and same parts to connect the gears...

i believe the guy's name is DLB**** on this board, but he's making power in the 500hp range on a stock f22 tranny i believe...

 

Nick 15's flat is not bad at all.... do you just have H22a with like I/E/H ? I was at the track last night... I ran 16.8 with i/e, F22B2 motor and 15.9 with 55shot DRY ZEX. (sprayed in 3rd) So If I can swap out my F22 with H22 and run 15's then with NOS i'd get mid 14's Easily. And That's not too far from my 13's flat goal. I think that a 8psi should do it. Am I wright?

when i said "not designed for high reving..." i meant conceptually. being that the gears are longer, they were clearly not designed for the higher revving h22, as it would limit the acceleration times on the h22, not that the tranny couldnt hold the higher revs

Nick: in general, if your shifting from around redline to the next gear, how far down on the tach does the F take you, ie compared to an H tranny (its usualy below the stock vtec engagment point, correct??)??

mods are:
-oem intake with k&n drop in filter (removed resonator obviously, also headlight for a cooler ram air afferct
-mugen header
-kteller 2.5" custom exhaust
-removed butterfly system from intake manifold
-p28 ecu custom ROM by gimpyaccord
-vafc
-removed everything from trunk area including sound deadening

also, my car dynoed 203 at the wheels...it has been called unusually healthy, which i do agree to...compression is great on all 4 cylinders and it is really quiet at idle with no valve ticking or anything...i personally would not expect to see such a motor as mine seems to be just a lucky pick...but your results won't be exceptionally far off...

correct...the high lobe cam engages at 4800 and the timing advances at 5000...this seems to keep the surging effect of vtec to a minimum...just nice smooth power...i typically shift at 7500-7600ish...the f22 tranny usually plants me square into my vtec engagement point (4900ish) for the 1-2 shift...i'm usually around 5100ish on the 2-3 shift, but 3rd gear is just so damn long...i cross the line typically at about 6600-6800 in 3rd which is a little over 90 mph...

the h22 tranny should definitely gain me at least .2 in the 1/4 mile, hopefully more...we'll see i guess...
