specific differences between Type-S and Euro-R

[cp[mike]]

ive never been too clear on the differences between the H22 Type-S and the H22 Euro-R, until recently i thought they were interchangeable names for the same motor... but apparently they both are rated at 220 hp, but the type S is 10 ft lbs less than the euro R. from looking at pictures, looks like they both have red valve covers, but the type S has the standard H intake manifold while the euro R has that well known euro R single runner mani...

any specific internal differences? what car models did they come in?

[LawdoG247]

i always thought they were the same also.

[cp[mike]]

nobody?


heres my current understanding... the h22 euro R came from the Accord EuroR, while the H22 type S came from a Prelude, not quite sure what trim, perhaps the Prelude type S or something. stickydiljoe is running a P0F TCU which he says is the EuroR TCU, and P0x usually refers to accords, so that helps support my theory. of course they are both H22s, but it seems like the euro R was a slightly better tuned version compared to the Type S? so which one is the one that they always sell for $4k+ ? do both sell for the same amount, or does one usually sell for more?


but besides all that, what im really curious about is the actual physical differences between the two. anybody know more information about block/head differences, tranny differences, etc?

Mike, i think they had a post comparing the two on Hondaswap.com

It was a while ago, let me see if i can find it...

This should be a good thread. Http://www.aj-racing.com sells internal head parts for both motors, might be worth contacting, especially since they sell the camshafts for both motors.

that single intake runner really does make a difference in the upper RPM range. that could be why there is a torque difference. other than that i believe they are the same motor. the trannies that come with them may differ which may be why the power distribution is different too.

bump for some elaborate answers!

manifold comparison, no real info yet





edit: check this http://www.honda-tech.com/zerothread?id=641555

same info as posted in the "possible swaps list"

only issue is that it says 217/163 for both, which would mean the mani didnt make a difference... which its known that it does... elsewhere ive seen that the euro R makes ~10tq more than the type S. still researching

The Prelude Type S (engine code H22A) is a 220 hp JDM-only engine, with beefed up cams, intake manifold and pistons.

The Prelude Type SH (engine code H22A4) is an engine no different from a base model 5th-gen Prelude. It's 195 horsepower, with nothing special about it.

^^ interesting. also:

The jdm type-s and euro-r accord have the same hp and torque, take your pick.

^^ for some reason im not believing that that is true.

thing that sucks, is that nobody really knows details about the two. people know all about the intake and exhaust manifold and tranny differences, but no specs/info about blocks or heads :\

I think they might have different head stamp codes also...

I remember something from awhile back on HT...

[xScott]

Well, the cams have different part numbers, so chances are very good that the profiles are different.

This thread should eventually be cleaned up and stickied.

[Accord R33]

Ill add it to the wiki once all the info is straight...

Found something that appears to support your research...

thanks justin, thats the same number that ive seen elsewhere...
