engine deciding help

so ive been planning on building my own frankenstein h23vtec because i have a h23a1 laying around and was gonna buy a h22 head, and build it up before swapping it in... but thats seeming like too big of a project to focus on now, and im finding myself being "picky" about the head i want....

so i began looking at engines on craigslist, and came across two F20b Euro R engines. it is a blue top, and says Vtec on the valve cover, and F20b on the stamp for the block. I did a little bit of research and i know the H22a Euro R, and F20b Euro R different as far as torque goes, but i can always modify it in the long run to get more out of it...

also heard the h22 euro r, is heavier than the f20b?? probably not by much though...

with the f20b being a 2.0 motor, i will probably save gas too right? unless i build it before swapping it in.
but anyway, what are the exact internal differences between the h22, and f20b euro r's? it seems like most people are saying the f20b has an h22 head on it, its just a destroked h22??

anyway, any advice on this topic is great, theres views both ways as in, go for it, or go for an h22 on other forums, some say h22 more powerful, and better engine, some people saying f20b is more powerful and better engine....

this is first of my looking at an f20b euro r, because it is an accord engine, and really didnt know about it until i came across a great deal on a low mileage one from an engine warehouse by me, looks legit, looks like its in great condition... right around $500, unsure if it was the one made for manual or automatic, havent called yet, im gonna call tomm.

Re: engine deciding help

stay away if its auto. its whole different engine then

"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. The F20B manual version also utilized stronger cams, intake and throttle body from the H22 type S. The difference between f20b manual (200 hp) and auto (180 hp) is cams, intake, throttle body and the gearbox for manual come with t2t4."

Accord SiR wagon, SiR-T F20B 97-01 2.0 L
Valve train: four-cylinder, DOHC VTEC, 16-valve
Bore: 85.0 mm
Stroke: 88.0 mm
Displacement: 1997 cc
Torque: 145 lbft (197 Nm) @ 5500 rpm
Horsepower: 200 hp (150 kW) @ 7000 rpm
Red line: 7400 rpm
Compression: 11.0:1

so yes the bore & stroke are smaller than h22s

Id get type R or S h22a

and btw, type R accords use H22A TYPE R (h22a7), f20b isnt any "R"

Re: engine deciding help

I hadn't decided anything yet.... Otherwise I would of told you a week ago, but I am probably gonna go pick one up in Pennsylvania today, the bare head... I got on to let u know actually. Same deal but local so I can see it in person.

Thanks for the info type t. I read things similar but didnt find that info on difference between auto and manual, I wasn't searching for that lol...
But I'm just gonna stick with my original plan to get an h22 head and build an h23vtec with my h23a1 block.
I know people say that it's more expensive and time consuming to start with an h23 but that's fine with me... The engine in my 95 is still running strong, so I have the time, and I know that my own custom build will be cheaper than buying a whole engine just to do the same and build it anyway...
