Ok so I’ve been doing a bunch of research for what engine set up I want to go with in my em1 project. I figured initially to go with a b18b because theyre so cheap, parts are easily accessible, I’m familiar with them , they like boost with head studs and rod bolts ect. Then I started looking into h22a using the h2b adapter plate. 200 hp na is awesome, I have b series solid mounts, a clutch and some serious axles that came with the car, which I would be able to use with the h2b kit. No cutting the floor, no poor axle angle, no f’ing with cable linkage, ect ect Then I saw the jdm f20b and started doing research on it. Iron block, not frm lined like an h22a. 200hp. Obd2. And the best part, the price- Toronto jdm has them listed at $650 for a complete engine. I could go catch the phantom with the mrs, spend the night, and come home with a motor! This seems too good to be true. \*Why are they so cheap? Will it never pass us obd2 emmisons? Are they prone to problems? I’ve heard of oil delivery issues, but that’s about it. It seems like a 200 hp 2.0 dohc boost-able (probably a head spacer to lower compression a bit) would be worth it’s weight in gold to Honda people. What gives? ---

If I am remembering correctly from when member “Slomies” here was doing research on his accord build…that there was also an f22b using in japan that was basically a DOHC vtec accord motor…which is essentially an H22 but some minor differences I guess…for the longest time he was also researching the H series heads on F series blocks too… might be worth shooting him a PM asking him if he knows anything about the f20b. ---

Yeah, the f20b is a jdm only accord sir motor, from I think 97-01? I know the iacv is different, along with some othe small things. But it just seems to good to be true. Run it in a civic with a pretty much stock h22 map on a chipped p28. Siqqq ---

There was also a sohc f20b, but that’s not the one I’m talking about Wiki- > **[Honda F engine](https://en.m.wikipedia.org/wiki/Honda_F_engine)** > > The Honda F-Series engine was considered Honda's "big block" SOHC inline four, though lower production DOHC versions of the F-series were built. It features a solid iron or aluminum open deck cast iron sleeved block and aluminum/magnesium cylinder head. This engine was also used in the Rover 618i, assembled in Swindon at the Honda facility.

From what I’ve read it’s based on the h series and was kind of a test mule for the f series found in the s2000 Idk man. It’s such an odd engine. I’ve never even heard of it until now!! ---

> [@Jam](#): > > Exactly. Thats another thing that scares me. That’s probably why nobody runs it…if you blow it up what do you do? if it’s H series based I’d look into whether or not it has the auto-tensioner that is known to fail frequently on the H series and find out if any parts are interchangeable… is the difference in displacement from the H2223 due to bore or due to stroke?

Jam, after seeing many dyno’s, H22 all motor is a great option paired up with an H2B tranny setup. Dirt cheap considering what they are…big displacement…fun, useable power. ---

if you are a straight NA man i would look at a H2B setup. The biggest problem i came across with H22s are the sleeves. If you want to run a higher comp. piston you need to either sleeve the block or there is one brand of piston that will work with the cylinder walls. You also need to take out the balancer shaft which is a 50-60 dollar mod. from QSD. But besides that i have been in a H2B eg hatch and for a NA car w/ a B16 trans it pulled very hard. ---
