So we know the Type-S and the Euro-R H22 are pretty much the same. 11:1 compression, "Type-S" cams, 220bhp...yada yada yada, with the main difference being the ATTS unit in the S and the LSD tranny in the R. But where im confused is if they are both rated the same horsepower and the Euro-R intake manifold is suposed to be better than the "dual-runner, IAB" manifold. How are they making the same power? The reason i ask is im thinking of getting a Euro-R manifold to throw on the type-s but if both engines are making the same power, will the Euro-R maniolf benefit me? I always thought the Type-S intake manifold was the same as the USDM H22s, but if this is the case how is it making the same power as the Euro-R with the Euro-R sporting the better manifold?

 

The Euro R manifold perplexes me. #'s dont lie. If the R makes more power, thats just the way it is. This is probably the only OEM part that makes more power than aftermarket parts.

Good question you ask. Hopefully somebody will help us out...

 

This is confusing to me as well, unless the Type-S manifold has something special to it or the Euro-R motor is missing something, i dont see how they can make the same power yet have different intake manifolds. Specially when its been said that the Euro-R and the S have the same block and head.

 

Well ive been doing some research and it seems that the Type-S Prelude also had a different intake, throttle body (62mm), and larger exaust system (2.25"). If this si the case i can see where the Type-S would make the same power as the Euro-R as long as the Euro-R didnt sport any upgraded parts like the S Prelude. I think im gonna throw on a Eurp-R manifold on and see what happens.

 

this Accord Euro-R (in europe is called Accord Type-R => ATR) with H22A7 makes "only" 156kW = 212hp not 220hp
Im not sure about Type-S cams in ATR...
Other specs like same cyl.head, pistons, cr 11:1 etc. seems to be ok

 

I am very sure that the Euro R does not share the same head as the Type-S. The Type-S head was hand-finished in the factory and the valve seat angle is different from other H22 heads as well.

 

Just when I thought Revi knew everything...

Where would you get a crazy thing like that?

Ah yes, i forgot about this. I read this before somewhere also, i forgot about it. So it sounds like the Euro-R manifold might benefit the Type-S....mmmmmmmm air flow.

 

the head is different..type s =P5P, euro r=PDE but the euro r has the same cams,port and polish etc...the only difference with the head is the webbing on the back, (you know what i mean if you ever tried to install a euro r mani on any other h22)...which is why i never understood the hype about the euro r mani...the runners are more efficient but the plenum is smaller..

I always hear about the Type-S having P5P stamped on the head but mine is stamped p13. The ecu is p5p.

haha revi got pwned

lol

like was said

the euro r has 11:1, teh sexy manifold, a regular h head (with the exception of the intake manifold setup), and a regular exh. mani

the type s has 11:1, factory ported head, supposedly a better dual stage IM, and a bigger exh. manifold, a better intake tube "dynamic chamber" thing, and a bigger exhaust.

they both have the same cams

 

Hey man, you cant get pwned in your own thread, its againts the rules.

 

my bad...i thought i got that P5P info from a reliable source..but then again reliable sources are few and far between....anyway, i own a euro r so i can say positively that it has PDE on the head. i've also dismantled the head before and it does have high lift cams.

The block is stamped H22A instead of A4, but the head is p13. Unless HMO swaped heads on me.....ill FOKIN GO CAVEMAN ON EM!!!!!

wow dude, you almost answered a question ive been having for so damn long. what does it say on your head after the P13? anything else? HF1 or HF2?

i know the head i have has a light port and polish according to the honda.co.jp website..and the euro r has dual exhaust (we at least 1/4 of it is) so how is it smaller??

 

one of the big deals honda made about the type s on their website was about the bigger exhaust manifold and exhaust they used on the type s

its also in the SAE article on it.

btw you drive a lude with a euro r swap in it? I'm in raleigh also....

 

i feel left out......i know nothing about a euro r accord. except that the i/m works much better than the types/h22

this might be a dumb question but why is the driver on the left side? is it the same in europe as here, but they just drive on the wrong side of the road

lol

i think in certain parts of europe they drive on the right like we do

 

i always thought they were right hand drive for some reason

 

only the english drive on the wrong side of the road here...

and i'm pretty sure the accords in the pics above are not euro-r....
those are european type r...

the euro r was only sold in japan....



that's a euro r...

Thats pretty much what i wanted to hear, i just wanted to make sure the Type-S intake manifold did have anything special that made it equal to the Euro-R. I didnt want to spend money on a Euro-R manifold only to not make any power.

So i will go either Euro-R or maybe even the Skunk2 Pro Manifold( ) Do i dare? LOL.

P13 HF-1 is what is stamped on my Type-S head.

 

ups, sorry for misinformation...

yes, pics that I posted are with european Accord Type-R, H22A7, 156kW, chasis code CH1 and of couse LHD. Only England, Japan, Australia and other islands are RHD. I just thought that in US they are called Euro-R...
