Hey man, I hate to burst your bubble, but its probably better you and all potential purchasers are well informed. The motor you have is not an Accord Euro R motor. The Euro R was produced from 03-07 and takes the form of the TSX in our domestic market. It is a 220 hp version of the k20 motor.

The motor you have is a very rare one. The H23A vtec motor produced only produced from 99-00. It was placed in the limited production Accord Wagon SIR. The blue valve cover is a dead giveaway. People will often mistake this for the F20B, which also had blue valve cover. This motor produces slightly less HP and slightly more torque than the H22A. It's hard to find accurate specifications on this though. A lot of info says different things, however, honda did a press release stating that this H23 was a brand new engine beginning production in 99. Limited info can be found on world.honda's website. http://world.honda.com/news/1999/4990121.html

Nice rare JDM-ness.
I wouldnt trust what the guys at Noyan say as far as I could throw them - but their motors have always been quality to me.

I bought a GSR motor there, and it put down 173 to the wheels in 99% stock form. I was impressed.

If you want more info on this motor - Google "accord wagon sir"
