H22A or F22B?

[owequitit]

i LoL'd @ diesel truck. Sounds like mine right now.

No kidding!

Changing my O2 sensor helped a ton, but before that, when I hit VTEC, it seriously looked like a diesel under full boost. Left soot on my bumper like one too.

[owequitit]

see that's another reason I was thinking of avoiding the H22, I know it's more finicky and also has NO power down low, it's all up top, hopefully the F22B isn't like that, I like a little low-down grunt.

Honestly if they're both like that, I'd consider just getting a rebuilt F22A and doing some work to it, I like the F22A's "torquey" nature.

I don't think the engine is finicky as much as the P13 is a doo doo ECU. Half the time it isn't sure what to do, and the other half it just doesn't do it very well. They run pig rich, make the car idle funny, and do all sort of inconsistent stuff.

Realistically, most people have good results when they install something like a P28 and have it tuned correctly by someone who knows what they are doing.

As far as power goes, it realistically is about the same as an F22 out of VTEC. It won't feel as strong because of the difference in low end vs high end power, so off the cam you will always feel deprived, but realistically, it is just as quick down low too.

Also, the H22 will be much stronger in the midrange if you have the VTEC crossover moved to where it should be, which is about 4800 if I remember correctly. You won't get the "KICK" of VTEC, but it will pull all the way through, instead of just waking up at 5500.

or just get the P06 and get it chipped by someone on here with the P39 basemap if you cant find the jdm ecu.

i personally love my F22B. i went with it bc i couldnt afford an h22 and im not sorry i did. it does feel nice in the low rpm range if thats what you are looking for. plus the dual runner IM helps out a bit once you kit about 4200rpms. it has been very reliable and good on gas. if i drive easy i have gotten 30mpg on it. with a good clutch and lighter flywheel and your basic boltons it moves pretty good. gets my vote.

Ill go with the f22b cuz that motor is direct swap, and
u can reuse wirin harness and even ecu, for now, till u wanna chip it or go with a p series ecu.

f22b is cheaper liek every 1 knows but its a GREAT motor for a upgrade with out spendin over 1000, u figure it will b 1000 total with shippin and new plugs wires etc.

f23/h22 frank. im in the process right now on my engine stand. if i check correctly using the cisco calculator ahh nvm..... making it a long story


depends on the money. I would go F22b since good for daily use. my h22 as a daily its ok but eats more gas and @ $3.06 a gallon and 45 dollar fill up I would go with the F22b. but I get around 26-28 mpg but thats with a semi tune running mid to high 14's low 15's on street tires.

I was doing some research on this, and I noticed one major difference between the F22A/B and the F23.

It might help explain why many of the people who have done this, have experienced bottom end failures.

The F22A1/A4/A6, as well as the USDM and JDM F22B series, all share crank bearings with the H22 and H23.

The F23 however, appears to have much smaller bearings, which most likely means that it is probably less tolerant of high revs.

Just something to look into.

after reading all of this I think the choice is clear, I think the F22B sounds much more up my alley. I know the H22 has it's benefits and all, but honestly I've never been impressed much by the "200hp H22A!" whenever I've driven a car equipped with one, in fact I had a 95 Integra with the 142hp 1.8L and it felt just as strong as a couple of H22 Preludes I've driven. (could be the huge weight difference too though)

H22 preludes? Usdm ones? because my car drives nothing like the h22 4th gen ive drive and the my friends 5th gen ive drove... But i guess it has to do with how you have your car setup.

The choice is obvious if you dont want to spend money.. f22bs are cheap and as much as people talk about turboing them, i think i can count the number who have in one hand.

I was impressed with the f22b power, but its slow.

Listen to whom ever you want, or your heart desires..

Yes Jose's(d112) f22 is fast, but its also tuned. And its also dead now cause he forgot to change his Timing belt.


Ive owned both hands down the h22 out performs the f22b any day of the week. You say it doesnt have power downlow? Remember that it doesnt take V8 torque to get our hondas moving fast. Mine even has 100k documented miles and its hella fast!

Your car must not be tuned right. I get better gas mileage than my F22!

H22a is a direct swap too, And if you know someone who knows tricks you only have to run 1 wire for Vtec.







Anyways just save your money and go to school.
