F20b in an EF?
Has anyone ever swapped this motor into the EF chassis? Ive been reading about this motor and a buddy of mine has one in his lude.. but i haven't been able to surface any info about this motor in the EF chassis. From what i can tell it swaps in just like the h2b. The only headache i can think of would be wiring since this motor is OBD-2.. aaand bottom end parts would be a pain to source out..
any other info comments, thoughts, pros and cons blah blah blah regarding this motor or swapping it to the EF chassis would be appreciated
the intake manifold, headers, cams, valves and springs, anything that bolts up to the head or is an internal part of the head are interchangeable between the f20b and the h22a type-s, as far as internals like the pistons,rods, crank ect. id say no they are not interchangeable, but to my understanding the internals are pretty strong from the factory.
This engine series was used in the CF4, CF5, CF9, CL3 Honda Accord and Honda Torneo from Japan. It uses a DOHC VTEC cylinder head similar to the H22A found in the Prelude but was designed to comply with many countries' sub-2.0 liter tax. The automatic transmission versions received the lower hp version (180 hp), as it was tuned for more mid-range torque than its manual transmission counterpart.

Re: F20b in an EF?
It's pretty much the same as an H22 swap, wiring, mounts etc.
Here is a thread on CRX Community about it.

I would check www.explicitspeedperformance.net as the H and F mounts are the same.

As I said, if you don't like my answer, then search for yourself and don't post asking for help if you don't want the answers that are given to you.

Deph i never said i didn't like your post. It was just bland, and i have already seen that information, a Google search brings that up. and believe me i did use Google. I'm not asking to be spoon fed.. i didn't create a thread saying " i haz aN cAr n i want an moter, tel mee everYting abOut swApIng mOteRz aNd how duz i gEt an VtaK!? KTHXBAI" i was just seeing if anyone on here had any MORE information regarding this motor. There isnt too much info due to the parts not being as readily available, hence the low usage of this platform. I was just trying to see what options i would have after swapping in this motor.
Don't worry about it though. Lock this fail thread.

"but i haven't been able to surface any info about this motor in the EF chassis."
Looks like your question was if it would swap into an EF - not what options are available for the motor.
Obviously you can swap it in.
As far as OBD-2 goes, just go OBD-1 and change out whatever sensors aren't compatible.
Now, you want to know what upgrades are avail for this particular motor? Shouldn't be hard to search for that. Might not be a lot out there, but focus yourself and it makes it a lot easier. Are you going F.I. or staying N.A.?

Re: F20b in an EF?
Then don't be non appreciative if the info that WAS given. I said since this swap is not readily done especially in an EF, you aren't going to find information on it. Pretty much all the info you are going to find out about the motor is what is on google or wikipedia because everyone for some reason prefers the h22 over the f20b.
I don't know what you MORE information you want about it, you have the complete specs, its better than the h22 as they have FRM sleeves (weak) and the f20b has regular cast sleeves like any B or D series. If anything I would suggest you ask over in the prelude forums if the info that I posted was not suffice.

Re: F20b in an EF?
Or if you read the first sentence "Has anyone ever swapped this motor into the EF chassis?" A poorly formed paragraph can be read so many ways. My bad. What I was looking for was an individual that might have swapped this motor. Not if it was possible to swap it in (its obviously possible).

Re: F20b in an EF?
if you want more info just look up h22's in crx/civic's, there's hella build threads about them and as stated before the f20b is a destroked h22, thus meaning that if you find something about an h22 in an ef, you can safely assume it goes for the f20b as well.
