On paper, a stock F22B1 will make 147lb-ft at 4500rpm, while an 1994-97 H22A1 USDM will make 158lb-ft at 5500rpm.

What I would like to know, is, although the peak hp favors the H22A1, how do the figures stand for this engine at 4500rpm, in order to make a direct comparison with the F22B1.

If any of you know the numbers, is it possible to compare how much torque they both deliver at, say 2000, 3000, 4000, 5000 rpm?

The reason for this is I'm *dreaming* of eventually swapping in the H22A1, but I doubt it makes as much torque in the lower RPMs as the F22B1, and it really matters to me, since most of the time I dwell around and under 3000RPM in my peaceful daily driving.

Thanks for the enrichment.

Edit: Please stick to stock numbers if possible, obviously because mods could send numbers in any way, and everything would get too debatable.

well the h22a1 was from 92-96
97+ was h22a4 i believe

 

Yes you're right, it ended in 96. It's the one fitted on the 4th gen, BB1 chassis Prelude VTEC

 

actually, over the years and all the dyno's i have seen, i believe the overall torque curve in the h22a is better over the entire range (or at least most of it if not all) than the f22. Higher compression, DOHC, VTEC + 2ndary intake runners allow them to retain low end power plus high end grunt.

"The reason for this is I'm *dreaming* of eventually swapping in the H22A1"

I guess my ? would be... Why the USDM instead of the JDM?

 

Less costly, and also, I'd buy the H22 longblock, but mate it with my F22 tranny. I also don't want the JDM ECU, it is speed limited too low.

 

jdm=92-96 h22s are cheaper, lower miles generally 35-45k, and higher compression so it makes more power 197hp and 161 lb/ft torque.

a good low mileage usdm motor is $$$.

 

depends on if you get it off the net or from a low rent mom-n-pop dealer.

Alright folks, I don't like to interrupt, but I was looking for a direct comparison between H22 and F22. Technical info. Numbers.

Please start another thread to debate on price comparisons on different H22s.

Peace, thanks.

BTW, if any of you have dyno charts of these 2 stock engines, it would surely be very relevant.

 

f22 tranny on the h22 motor will hurt your low end power also b/c of the longer gears in the f22 tranny. when i had an h23 teranny on my f22 motor the gears were hella close, and i was constantly shifting. it was like night and day bn the f22 and h23 trannies on my car, and i think it would be more than fine if u got an h22, even though my friend in his 5th gen lude says how he cant drive it under 2k rpms cause it boggs, whe i drive under 2k all the time. now, i dont even shift past 3k, and mostly keep under 2500

 

Trust me you don't want the f22 tranny... Tried it at first just to see how it would work... H22 tranny is SO much better.

 

I know you want stock vs. stock but at http://www.h22a.org/h22vsf22.htm there is a dyno of both engines. The f22 has a DC intake. The H22 has a DC intake, spoon vtec controller and rechipped ecu. It's a start though.

 

Kasper: Trust me, I do want an F22 tranny, that is not a question I asked. Drive 60,000 mile each like I do and you'll want the same thing when you see the gas bills.

GovEE: Best answer yet, thanks . But thats an F22A4, I believe, it has nothing to do with the power layout an F22B1 has.

 

that vs dyno plot is weak... what f22 and tranny is that mess.

not impressive... as I have dynod my f22b1 with nothing but a exhaust and crushed those f22 numbers.

EDIT: werd, b1 ownz the a4.

I dont know about any numbers on paper betweent hese motors but ibe seen a race first hand between two and the F22B1 held its own when in the lower RPM ranges. The H22 only got away because it reached its powerbnd i little quicker. the F22B1 is a screamer for only having 1 cam. But the H22 is just a little quicker.


Im using the F22 tranny from my F22B2 on my JDM H22. daily driven with w new cltuch for awhile til boost in introduced

 

Wait, are you saying that an F22B1 is a lil slower than an H22A accord?? i tought that the H22A accords were really fast

 

its called sarcasm.

 

You are right about the savings on gas bills with the f22b tranny 'sauceman'. I have the same combo u want and a mate has the full h22a combo and i save soooo much more gas then he does, especially on the highway.

 

low end for low end, when it comes to a street race I can run a h22 car no problem... the hp advantage is what edges me out in the high rpm.

I dynoed my car @136 ft lbs with just a catback and modified factory intake still running the honda paper filters... on a 4th gear pull.

thats like about 156 at the fly with 15% drivetrain loss and 163 with a 20%... I figure I am prolly looking 15-18% loss cause this **** clutch.

I have my dyno if your curious I can scan and upload it for ya.

 

I know what u are asking, before i did my JDM H22A swap i loved my TQ at 4300 rpms on my f22 and moved felt pick up now that i have my H22a in my accord moved but i feel the TQ at 5500 rpms and i make it my car rev always high to get that tq level to pull pends on what uwanna do in the future do u wanna Fored induction it or all motor etc, btw hows the F20B ? that the story with that motor meaning HP TQ levels and rpms relines ?

 

if you take the tranny into consideration, gearing w/ an h22a+tranny should give it an ultimate advantage over a similarly equpiped f22 (w/ f-series tranny) throughout the entire powerband.

 

Well, when it comes to difference in perfomance between an f-tranny and and H22 tranny, there is about 3 tenths of a second difference, and that's pretty much it. It's a sacrifice I'm willing to make. And as I said, I intend on working on the torque of the engine more than high end mods to cover up for the longer gearing. I'm more looking for a torque monster than a screamer.

What I love to think, is that many parts I have on the F22B1 will fit on the H22, for example the flywheel (most important to me), but also the pulleys, the exhaust except for the header, I guess.

So to me, knowing for sure that the H22 will give out equal or more torque in the low RPMs, (2000-4000), is important, given that I will use the tranny with the longer gearings. Then the high end HP will be a bonus, that will not affect the driveability.

This is why I need stock dyno charts, to know exactly what I'm working with at the baseline.

Aight, before the thread goes out, anybody else have valuable info?

 

I offered a mostly stock dyno with a factory tune but thats all I have... I never dynoed completely stock.

You mostly looking for dynos for comparison or what?

 

Yeah, to compare.
