so i am planning to swap an h22 into my 92 accord 4dr. i have done enough with the exterior for now( 17 inch wheels, and a 2 inch drop....future, paintjob and that's it..sleeper) and am now looking to do engine work. i came up on 2 grand and have decided to buy an h22. but before i do i want to hear all suggestions and opinions you guys have.

here's what i've heard: some say the h22 is terrible with high boost and will not hold it well, but then again i read up on some dude who has an h in his cb7 and is running 604whp. so there goes that theory. some say the f22 is better with boost and can take more punishment. i've heard plenty of different stories, but the guy with the 604whp h22 convinced me that the h22 route is tha way to go. what would you guys suggest is the best engine, no bias arguments just straight facts please.

if i do go the f22 route i would obviously rebuild the motor because i don't think 180k miles on the motor is a good starting point for a turbo. h22's come with like 40,000 average. how much would it cost me to rebuild the f22, and/or where could i find an h22.

goals: 300whp-350whp, flat 13 second 1/4 or less. thank you for all your suggestions in advance, and sorry for the repetitive topic.

 

There are Pro's and Cons with either, but for boost you'd be better off with the f22bx family of engines. It comes down to two things

The F22 starts with a base compression ratio better suited for boost (8.8:1 cr) as opposed to the H22's 9.8:1 to 11.0:1cr
The F22 has a Wet-Deck, Ductile Iron sleeves in an aluminum block design as opposed to the H22 which has no sleeves and is a dry deck design.

The H22 has some additional oilers in the crankcase for the pistons, but the F22 hasn't shown a problem with the bottom end.

The F22bx non-vtec cam is better suited for boost as compared to the H22's. A short duration cam is better suited for Turbo applications. The H22's more radical v-tec cam will actually loose boost efficiency once the v-tec cuts in.

so stick with my f22 engine you say? i was considering that option but that would mean that i have to rebuild the engine. how much would that cost? and as of now my engine shakes like a **** when i don't let the car warm up for at least 2minutes. it goes to about 200rpms then it bounces to 900rpms and then goes up and down for a long while, so what i do is i take my foot of the brake and step on the gas and keep it like at 900 rpms, it does that when i go into neutral. besides that no problems, except for my transmission which grinds like **** when i step on it, if i switch gears at 6000rpms it grinds like ****, does this second and especially third gear.

 

Well the guy you heard of getting 604whp out of an h22,Im sure he had his frm h22 block sleeved.
so there goes the 2000 dollar budget.

you could rebuild the f22 you have with forged internals for the price you could sleeve the h22.
but you would still have to buy a decent turbo manifold and innercooler to get 300 whp.
then with the price off everything else your going to need your a good bit over two grand.

Both engines can make good power it's up to you wich one you want to build.
Man if I won the lottery today and money was no object at all.I think I would sleeve an h22 build it with forged internals and have hotrex make my manifold and down pipe then boost the crap out of it.

But with $2000 dollars Id just turbo the f22 you have at like 8 psi and set a lower goal of about 200 whp.That way atleast your boosted and you still have more power then a stock h22.
If that motor with 180k blows who cares by another f22 for 400 bucks.

 

Huh I haven't heard that the h22 cams.I may pass on my g22 turbo then and just boost the stock f22 in the car.I may use the money I was going to spend on the head for some forged pistons and an engine seal kit.

 

ok good info so far, but just so you know i was aware of the fact that to squeeze 300whp out of any honda engine would cost more than 2 grand, at least for an accord it would.

my plans are to spend about 5-7 grand on engine alone, so that would leave me with 3-5 grand to buy a turbo, header, exhaust, intake, fuel injectors, and all that other stuff that's associated with making 300whp.

 

Good deal at least you know you have to pay to play.

Hey P have you heard anything about boosted jdm f22b's?DO they have more of a NA setup built head like the h22.I would imagine that the f22b would have short duration cams

 

One characteristic that all JDM engines boast are a higher compression ratio over their USDM counterparts. It's the main reason for the power discrepancies between the two markets, and it's also the same reason why they aren't certified for use in the U.S.
The high(er) compression makes it harder to control certain exhaust gasses (I believe NO (Oxides of Nitrogen)), and the high(er) compression ratios make it more problematic to boost (and control detonation).
The ironic part of all this? Plot the dyno curves of both an F22b1 and an H22 and overlay them. What becomes apparent; they march almost in lockstep until the V-Tec threshold is reached, where due to it's higher compression and more aggressive cam profiles and spinning the thing to stratospheric heights (8k), the H22 comes alive.

The f22 cams (Non-V-tec) are better suited for boost.
Look thru Isky, Crower, Crane or other cam suppliers catalogs; and you will note Turbo Cams are a short duration / high lift design.

One thing that never ceases to amaze me is how quickly guy's (dudes, etc)) are so quick to read the "604HP (Shouting for effect)" and believe it as gospil, but never ask the followup question "Yes, but for how long?" and "How much did it take to keep it there?"

I've NEVER seen a Long Term Review on "Wacky Wally's 604hp Wonder Wagon". I suspect it's more like: "OK, That was interesting; sweep up those pieces and take down that crap that's still attached to the engine dyno" Let's see what else we can spend the budget on"

to ressurect this thread, you guys have said the f22 can hold boost better than an h22, and that an h22 needs to have a built bottom end to withstand boost higher than 10psi. so my question to you guys is, which engine is more reliable? an h22 with 300+whp(built bottom end) or an f22 with 300+whp.

at 300whp, can any of these engines really be any good as far as reliabilty, cause this will be my daily driver. and P, i know about the follow up questions. i am pretty sure 600whp on a 2.2(correct me if im wrong)L engine will not hold up very long if at all. that is why im going with half that, to keep my engine alive for longer than 10k miles.

side question: would a V8 5.xL chevy engine at 600whp be far more reliable than an h22 pushing 600whp? i would think so, but is the v8 really more reliable.

So would you say f22b2 &gt; f22b1 if one were to boost?
