Hello everybody, I'm a proud owner of a 1999 Lude Eudm. I'm from Italy so sorry for my bad bad english

I'm planning to buy a jdm H22A coming from an Accord EuroR with t2w4 (lsd).
Thanks to euro (the european money, not the jdm engine) the engine seems to be almost cheap, but I have ONE important question before bidding, I hope you would answer!
So...the owner makes the compression test and the result was 210psi in all 4 cylinder.
I think all of you agree with me that is good there is the same 210psi in all cylinder, but this isn't too low for an H22A that supposed to have 220hp and 11:1 of compression ratio?

I tried to check on the net if someone makes the compression test in an euro-r but...no results
If you can help me...thanks in advance

The JDM H22a is 10.5:1 compression ratio. If I remember correctly, I got around 215 +/- 5psi across all four cylinders when I tested mine shortly after I installed it. You'll know if yours is the euro-r, if it has the red valve cover or "red top".

I'm sure mine is an Euro-R (red top and t2w4 tranny with lsd).
I'm worried 'cause the compression test seems to be too low...

You have nothing to fear. That compression number sounds just fine. The most important idea is to ensure all numbers are close to each other, which sounds like the case here.

When I bought my Euro R, I was told it put down around 245 across the board. You might want to get a leak down test or whatever done.

210psi VS 245psi.
What I have to do? You think it's very bad my compression results?

As long as all cylinders are making tha same com you are ok.If they wasnt i would worry bro we are going to video my dyno

Kinda digging up an old thread here, but thats probably a better idea than making a new one as the topic is the same.

I have a H22A8 11:1CR motor, and i did a comp test today. Took an average of 3 tests per cylinder on WOT.

#1 272 psi
#2 263 psi
#3 254 psi
#4 261 psi

Had a valve adjustment at Honda about 6 months ago, maybe wasnt so good of a job, but there is only 18 psi difference between lowest & highest value, (6.6% variation total), so i guess thats ok.
