H22 Vs. F20

I was thinking about doing a swap for my BB-4. Did some research and got 3 results.
F20, F22 & the infamous H22.

Wanted to make sure what F20 it was? Is it the F20B or F20C?

Secondly a good friend of mine mentioned that the H series were known for having weak crankshafts, and often broke when revved too high. Can anyone confirm this?

I'd like to have a fairly reliable DOHC with VTEC and more power. What's your opinion?

Re: H22 Vs. F20

Isn't the F20C the S2k engine...? Good luck mounting that in a FWD lude... H22's are completely reliable. You're friend is an idiot You can break any engine by over-revving it...

Re: H22 Vs. F20

Re: H22 Vs. F20

I has f20b in my 4th gen. And I wouldn't trade it for anything. Most H22 parts are interchangeable with the f20b. Its a great engine. If u have any questions let me know.

Re: H22 Vs. F20

The F20B is just a de-stroked H22. They made it for cars in foreign countries that needed to be 2.0L or under to avoid certain taxes and whatnot. The F20C is the AP1 engine. The H22 can take a lot of abuse if maintained properly. Tons of people run them and beat on them regularly with no problems. If I were you I'd go with an H22. But that's just me.

Edit: Yes, your auto F22 tranny will work with an F20B.

Re: H22 Vs. F20

Its fairly simple, same mounts, tranny will work fine, (gunna be slower than a turtle in peanut butter) but it will work. You have to change over the injector plugs, and a few others. Use a h23 timing belt tensioner and a H22 timing belt. F20b=156 teeth and H22=155 teeth. A few more details but all in all its pretty simple

True if he decided to go that route, but the f22 tranny on an F20b isn't a good combination for accel. But if you wanted to save gas then its perfect. I forgot you have an auto anyways so its gunna be slow regardless.

Re: H22 Vs. F20

F22 Turbo makes great power.

H22 makes good power, and it has the after market support.

F20B, as said before, is just an H22 with a shorter stroke.

I'm using an F20A (dohc), an H23 with a shorter stroke.

Re: H22 Vs. F20

I believe the f20b has iron sleeves as well, so great start for boost on future applications.

Re: H22 Vs. F20

id say H22 because parts are more readily available and the aftermarket is HUGE for it. Not to mention if you ever want to upgrade or repair it there are more people on here who can help

Re: H22 Vs. F20

You guys make the f20b sound like some engine that you cnt get parts for, when most of the parts that anybody would mainly change are interchangeable. And the the pistons are interchangeable with other f series engines. And there's web sites that offer oem f20b parts, so its not like its impossible, costly but not impossible but that's the price you pay to be different. So if your scared that you'll blow the engine or headgasket then go h22. H22 parts are more readily availible, but you can get f20b parts but it will take a lil longer.

Re: H22 Vs. F20

^^ is that directed to me? The F20b is a great engine, but H22 is too. Both have there down falls but I guess it would come down to what your personal choice is. Either have a engine that parts are easily ready, or an engine that parts are hard to come by and gives you braggin rights. I choose braggin rights.
