how available are the euro h22a7 ? and any one know avrg price ?

 

check ebay and maybe hmotorsonline.com might have em too.

 

Check forum FS threads, there's usually someone parting out a setup and you can usually pick up something cheaper than through hmo.

If you're not comfortable with that, then go with a JDM H22A from hmo.

One way or the other, just make sure you get the JDM ECU if you aren't planning on tuning. I believe the JDM ECU is tuned a bit better from the factory.
