Which engine is more powerful? H22A or F20B?
I want to slam my 2002 Accord-- Which would be the better setup- H22A or F20B? Which has more available upgrades?
How come no one seems to swap a B into the F?
Has anyone thought about the K24 from the 2003 accord? Will it fit?

Re: Which engine is more powerful? H22A or F20B? (hondanoel)
First off lets start off with hp and torque specs. The JDM H22a has 200hp and 161lbs of torque, while the F20b has 200hp and only 145 lbs of torque. 1 point for H22, 0 points for F20b. Another thing is pricing. A JDM H22a usually runs for about 2,100k, while the F20b runs about 3500k. With the extra 1400k in your pocket... you can work on internals euro r intake manifold, replacing belts and what not and even get a blue valve cover like the F20b 
. But i guess you can do the F20b, cause no one has it... But to me, its not worth the cost and its giving out less power than the h22. So recap... I'de choose an H22. H22a: 2 Points F20b: 0 Points. Other guys on here might beg to differ. Up to you man but hopefully i helped you in a certain direction. 
edit: Oh yea H22 of course has more parts for upgrade... but it makes me wonder if the h22 parts would just fit the F20b parts... since its an F series and has almost the same parts as H series. Anyone on here know?

in theory, the pistons from an f20b should be interchangable with other f-series blocks - but i've never seen any or had any way to compare them. since it is a non-usdm motor, if anything were to go wrong internally and the parts were NOT interchangable, it would not be cheap to get f20b parts.
the main differences i see between them are the displacement differences, and how the f20b shares the same bore and stroke as the f20a. an h22a head probably would not fit on the f20b if you were ever to **** it up. as for internal head parts, i would guess that they would fit, but i'm not positive.
for the money, unless you want it, the h22a is just a better deal. by the way, http://www.japanmotorimport.com has the f20b for $2300.

Performance parts usually tend to move your peak power into a higher RPM range. As you soon make power in the higher RPM range, you will need to build your block.
An F20B block can rev to 9000RPM and still be reliable. Why? Because the F20B has a better R/S Ratio than an H22A, and even better than the B18C! You could fully build your F20B head, and still make loads of power without even touching the block. 1 Point for F20B.
An F20B has 11.0:1 Compression. If you plan on leaving your block stock, when you add cams such as Skunk2 Stage II Camshafts, the higher compression allows the camshafts to take more advantage of it. Another Point for F20B.
Even though F20B might be more expensive, you must realize that part of the cost is due to the fact that it's a rarer engine, and the other part of the cost is because it comes standard with LSD.
As for interchangability.... You can use H22A Valvetrain, H22A Cam Gears, and even H22A Camshafts in the F20B head. Should one decided to build the block, one must bore the block to at least 87mm for aftermarket H22A pistons and sleeve it. You would then have a 2.1L Motor since the stroke is shorter, but this is good, since you can rev this sucker high!

Re: Which engine is more powerful? H22A or F20B? (All-Motor H22A)
the f20b is just a destroked h22a....basically the same engine, but the f20b is 2 liters with higher compression and way more high strung/peaky.....most of the h22a parts are interchangeable.....they're not ALL 200hp either...the auto motors only made 180hp...but the difference in torque is enough to slow you down .3-.5 in the 1/4 mile.....in a civic, that wouldn't be so bad because of the difference in weight....but the h22a would be a better bet all around...here...check this link out

it HAS to rev to make power.....much like the b series motors.....it was designed simply to meet the 2.0 liter and under class requirements for racing......it has a better flowing head stock (not as good as the h22a type s though) but the powerband isn't as ideal as the h22a is for our 3000lb cars....an f20b accord will be slower than an h22a accord....always...and the h22a w/ 5speed lsd tranny is still right at $2000...mine was anyway.....i think the f20b tranny is basically the same, but i'm not 100% sure about the gear ratios.....
it's also a less tuneable, obd2 open deck design.......you would need to convert it to obd1 to take full advantage of it's potential with some good tuning....i think the p13 can be used on it with the conversion harness, but it would still benefit from tuning since the air/fuel ratios are different

yeah for the most part f20b's runn cheaper than the h22aX's because the h22's are so much more insanely popular.
If you ask me The F20 has more potential... seeing as it was already pointed out that the f20b is just a de-stroked h22. The thing is that the f20b comes equipped with a heavier duty valve train and the higher compression ratio. So you could easily make a few valve train changes and meet the same torque as an h22, but have the capability to rev it a lot farther as well thus making a lot more HP.
For a street motor I'd vote f20b, but for a track motor I'd go h22
The ability to rev higher and fasted than the h22 will mean that cruising out of turns will be more fun (except lower torque means you wont hold the turns as hard) There are a few things you could also do to blow the lid off the power of a f20b
3 or 5 way Valve-job and P&P matched to a P&P IM/TB would see huge improvements, especially topside of the power band. It was mentioned new cams would succeed in making the higher compression more worthwhile. The stock block should be more than enough for most applications. Even with stock springs/retainers you could run pretty aggressive cams because they are built to rev to 9,000 rpms.
or as said previous stroke it, or bore it out to a higher displacement to give you that awesome head on a lager displacement (yay for torque!) block

Re: Which engine is more powerful? H22A or F20B? (All-Motor H22A)
make sure you know who is tuning your car and also HOW EXPERIENCED they are not just with tuning in general, but your car and motor selections specifically to see the best results.
The other day i saw a picture of a shop with a miata strapped to the dyno. Guess which two wheel were on the rollers. If you said rear you were wrong lol.
Like i run hondata.... so where did i go? One of the official Hondata dealers....
why? because they know the system best and obviously enough about hondas to be one of the like 60 Hondata official shops.

Re: Which engine is more powerful? H22A or F20B?
what is the redline on the H22 motor? If I eventually get a ton of money saved up I would go for the f20b just because sending it to Trinidad where the car is, 2.0 is in a lower tax bracket than 2.2, saving so much on engine taxes that you can actually mod it to give more torque than the h22 for the money saved..
possibly... even turbo it with the difference in cost.

Also, 2,100k is 2100000. 3500k is 3500000.
I certainly hope you're not spending that much on a motor.

Re: Which engine is more powerful? H22A or F20B? (All-Motor H22A)
if ur gunna boost it go with the f20. rod to stoke is way closer for more boost and less stress on internals at higher revs if ur N/A take the h22. just my preferance. and the f20 is 1000 bucks on ebay for the manual one 2500 with ecu and tranny and 3500 with ecu and lsd tranny

Re: Which engine is more powerful? H22A or F20B?
What I don't like about the H22 is that it has so low torque, rated only at 160 ft lbs. The F22a itself makes about 140 ft lbs. If you have a health F22a engine no point in swapping it out just build it up, F22a's are great motors.

Re: Which engine is more powerful? H22A or F20B?
No.... Because I'm about to buy an F20B and throw it in my Manual, 1994 Honda Accord EX WAGON! I blew my F22B1 and there's a guy around here with one freshly built 10k ago. It was in a prelude and would spit flames when he shifted!!!! Lmao... Seriously though!
Supposedly has ABOUT 300hp and 250ft lbs of torque... NO clue whats done to it YET! I'm beefing up my clutch and throwing on new CV axles (mine are BOTH shot!).... Is there anything else I should do??? Or will a clutch and lightened flywheel not be enough to handle the power of the F20B, w/ the stock F22B1 Tranny??
I NEED HELP!
Guy only wants $700 for the freshly built "Blue Top", I think thats a VERY fair price! Its the ENTIRE motor, including the ECU/TUNE/WIRING HARNESS' (Whatever the prelude needed i suppose! But he said the tune is for the MOTOR, not the car!) Is this true??
Thanks guys, yall are always the BEST!

Sounds like his full of sh*t, id stay away from it. If your looking for a swap, i'd recommend hmotorsonline.com http://www.hmotorsonline.com/shop/sc...age&item=30013

Re: Which engine is more powerful? H22A or F20B?
Two words, DYNO SHEET.
Google '300HP F20B' there will be pages of links, mostly leading back to here at H-T. Read Read Read.
As for the 'tune is for the motor, not car' means that whatever 'tune' the engine is running(and I use that word lightly) is just good enough to keep the engine running.
Anytime any changes are made to an engine, be it drivetrain, exhaust, intake, whatever, the engine should be properly tuned on a dyno.
If he ever had this tuned, he should be able to provide you with a dyno sheet, address of the tuning facility, and the tech who tuned the car.
If he cannot provide data proving that the dyno sheet are for the engien he is selling, then it is complete bull. On the other hand you will have to know what you are looking at when you get the dyno sheet. It is easy to fudge numbers for dishonesty and bragging rights. It is also easy to make something look more powerful than it really is by tuning it for a specific number rather than a complete and proper tune.
If you have the need for a F20B, rather than throwing good money after a questionable engine, just get one from a reputable importer. The cost is neglible and more than likely you will have some support after purchase if something is wrong.
