it doesnt come with the cover i think, thats why i m confuse about all this rite now and what does blue top mean?

blue top means the valve cover is blue.

If that f20b was taken from a jdm accord cf4, it should be dohc.

ok, i'll add a pic tomoro

my dad and i did not ask the seller ==
my dad made a decision to buy this because engine running smoothly and silently lol, and we didnt know what engine it is either ==

don't just simply buy without knowing what kind of engine it is, it's like marrying (buying) a Vietnamese wife and the worst outcome will be the wife left suddenly and leaves u with nothing

lol, i am lucky this time ==
will check carefully next time

not the F20B from CF4

Looks like a D series?

Not even close to F20B...more like standard PGM-EFi engine to me.
And definitely SOHC.

sadly to say that it is definitely SINGLE OVERHEAD CAM (SOHC)

but isnt it a F20B?
somewhere below the engine says so?

Its an F20B SOHC!
This engine series was used in the CF4, CF5, CF9, CL3 Honda Accord.

150hp/6100rpm
137tq/5000rpm
6400rpm redline
9.5:1 compression ratio
85.0mm bore x 88.0mm stroke

F20B has SOHC n DOHC versions... the one u have is obviously the SOHC version.

anyway, it is true that CR-V also use F-series engine?

ok, thx guys

it is a F20B. the first version from SM/CB Accords

F20B got many type wor..

CRV is B20B and K20A

ops not the blue top..

i thought the CF4 and cl1 uses f20b dohc. the one with blue top?

and TS, this does not look like a transplant. looks like the basic engine that came with the SM4.

if transplant, most ppl would go for this http://www.mudah.my/F20b+auto+tiptronic-11418502.htm it's cheap!

as i said f20b many variants.. not every one is a blue top..

http://en.wikipedia.org/wiki/Honda_F_engine#F20B

yeahh. i was saying the cf4 uses f20b. isnt the f20b that cf4 uses comes with blue top? or there are other variants?

http://en.wikipedia.org/wiki/Honda_Accord

Look on d bright side. At least ur engine is not d earlier carb fed SOHC F20.

What is the original engine used in SM4 (1991, 2.0l, imported from Japan)?F20A..

And I changed the ori engine to F22B, is this engine good?

And this F22B a SOHC or DOHC? how many valves and how many cylinder?

Comparing F20A (previous engine) and F22B (using now), of course the latter one got more power. it is also more fuel efficient. And after I use Shell Helix 5 instead of ENEOS (used previously), I have found that SH5 is more fuel efficient too (My experience)

Here the pictures of engine I took, please have a look and give any comment。 ThankYou
