Hi I have a question about the F20b DOHC type-r accord euro engine. I want to know what is all inter-changeable with the H22a such as internals (pistons, rods, valves, etc....) unless you know for a fact please don't just give me opinions as to im using this info to order parts for an up coming project. Also I dont really care who thinks what engine is better than the other, this is the engine im going with and there is no changing my mind so if you have an opinion id rather not hear about it. Thank you to anyone who gives me useful information. Oh and by the way just so you know im not an idiot I have done honda engines already i just never messed with this one and they don't make many aftermarket parts for them, if they do i just haven't come across them yet any info or parts would be helpful too. Thanks again

 

Well lets see this is what I can give you for now,

Bore = 95mm (F22)
Stroke = 88mm (not an H or F crank) need to know main journal sizes????
Deck height = 219.5mm
Connecting Rod = 145mm (C to C)
Piston = 31mm Compression Height (same as H22)
Piston Dome = 5cc (Higher than Type S)

and I am not 100% but I'm pretty sure that the head is the same as the H22A Type S. But as posted in another thread do not quote me on that.

I'll take a look through my manuals to see if I can find crank and rod journal measurements for you.

 

thank you that is helpful. what im tryin to do is build an all motor F20b dohc engine but i cant find aftermarket pistons, rods, valves, cams, etc. this is why i want to know if the h22a internals fit

 

I have read somewhere that the valves are smaller. From what I understand, there are two versions. 185 hp automatic, 200 hp 5spd. tq is lower than the h22. But the f20b has a higher rev limit due to the bore and stroke ratio. I know the cams interchange. Ive always been curious about this motor. My question is... Why do the Europeans and Japanese get all the cool ****?

 

yeah I don't know why that is I wish america would make a cool motor or car other than a v8. Im going with the 200hp 147tq 5speed lsd engine, i like it cause it is very close to the k20a for half the price

 

I read your post on another thread on this same topic. Will the real Euro-R please stand up! My Euro-r has a red valve cover and is rated at 220 hp. Just like the type S lude. And then there are two engines with blue valve covers. F20b and an H23 VTEC!! WTF?

 

I have heard and seen two different things about the f20b 1. it came with 200hp and 2. it came with 220hp. Im not quite sure which one is right but so far I do know that the real valve cover for a F20b DOHC is a blue, that is not my opinion that is from the places I have called about purchasing this motor. Other than that I do not know that is the best I can do to help. I say is if your bottom end says F20b and its a DOHC then it is a type-r.

 

k the f20b is the h22a type-s motor destroked to a 2.0 form the 2.2, so that honda could compete in touring races which the motor size limit is 2.0. it has the same hp numbers as the type-s h22 but less torque. the head is the exact same as the type-s, but to my understanding the internals are completely different. and the f20b has a blue valve cover not red, thats the type-s valve cover.

 

hmotorsonline sells two F20b's. One with 200hp and another with 185 hp. My H22 Euro-R is a JDM engine, makes 220 hp (RED TOP). The European H22 Type R makes 212 hp (RED TOP). The H22 EURO-R and the Type R have a single plenum intake manifold. The RED TOP Type S lude motor has a dual runner manifold. I would still love to see an F20b blue top in action. Ive heard they pull hard to 9000 rpm! CHECK OUT HMOTORSONLINE.

 

I heard that the F20B DOHC VTEC shares the same cams as the H22A Type S, so I guess its true that the heads are the same.

 

so to answer your question 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. ive been doing a lot of research on this motor cause eventually after my bisi-build gets boring im building an f20b.

 

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.

Let me know when your bisi build get's boring. I'll take it off your hands. Then build it to the next level and spank the **** off any F20B that you would build.

kilerintegra,

Just a heads up. When you copy and paste information from another website. Use some common curtesy and at least put it in quotes and give creadit where credit is due. Seems like I've seen that post almost word for word somewhere before.

 

yes that post was from another site im not tryin to say it isn't i just posted specs that I found about the F20b sorry I didn't do it properly didn't know I had to.

and this is not a "im better than you post" this is a question post so we don't care what you can build and who you can spank, really not interested in all that take it somewhere else please. THANK YOU

and to everyone that gave info on this motor thank you very much I think I know what im going to do to build this the right way....keep giving info though i will keep checkin back

 

Your welcome

But after this last post don't expect any more spoon feeding. Seems as though you now know how to use the search function & google

and good luck

THat's an over and out 2U!

 

just for the record I do know how to use google and it has worked well for me but I have not been able to find info on what pistons fit in the bottom end other than stock or what rod I can go with, and after 2 weeks of nothing but google i figured I would out source and see what other people know this is why i have started this post.

Oh yeah does anyone no who makes sleeves for this bottom end i will probably have it figured out by tuesday but I was just wondering if anyone has had it done yet?

 

Darton, GE or anyone who makes sleeves for the F & H series blocks.
.

 

ghost accord there really isnt much more you can do to my bisi-build, but when i get bored of it youll be the first to kno.

 

Thanks, Just one thing though. What has Bisi done to it for you?

If your at Bisi's limits you must be pushing the 250-300 Whp mark.

 

dos any one know whare i can get the 1998 honda accord sir Vacuum Hose Routing digrams from or any good pix of the moter that would tell me what goes whare on the im
thanx

 

i call it my bisi build cause all my parts are bisi's parts, but i personally built it myself, it has potential to be at 326whp, but im at 268 right now, bisi's headers help a ton, i was iffy on boring the block to 86mm from 85mm since the service limit is only .5 but i havent had any issues so far. another thing that i wish i woulda thought thru more was going with maybe 11.6:1 comp. max instead of 12:1 cause of tuning and gas purposes, i run premium fuel then some octane booster, instead of say 103 octane. from what im told i should be using race gas, so my motor wont last as long as it should but i recently joined the army and im going to be giving the car to my brother but with the stock f22b2 motor that was originally in it till i get back. then either do work with the f22a1 or start the f20b. and now im rambling and thread jacking so yea f20b h22a type-s. answer your question dude who was askin one?

 

I used to think the F20B WAS stronger than the H22 but when you factor in the extra .3 liters of displacement the H22 boasts...? I guess the H22 is the overall stronger engine. Plus the heavier accord chassis really could use the extra displacement which equals power. Yeah the F20b type S or is it Sir?...Is rated at 200hp but that doesn't necessarily mean it's better for the Accord. Alot of fun though. The hell with F ser and H ser, I cracked

 

I moved this conversation over to one of your threads

Sorry about the thread jacking kilerintegra

 

When you get it in and running. Post a video clip. I wanna hear it!

 

Xcuse me, can someone confirm that the SiR-T cams is the SAME as type-S? I'm doing my built right now, mild mods. Fully ported head to match with the SiR-T cams. Just to know the full potential of that cam. If someone can confirms that the cam profile are same, then i don't need to fork out more cash for the REAL type-S cam.

thanks
