I currently have an USDM service manual for 96-98 civics. For most mechanicals parts its pretty much the same.
But for electronicals im not so sure. For most of my works i am relying on the D16Y5 which is pretty similar to my D15Z6. Both are VTEC-E

Do you have any idea where i could find the EU version of this service manual. The EK3 is pretty popular in europe and russia but the only service manuals i can find are USDM.

 

You can try searching ebay, etc. Links to copyrighted material are not allowed in the forum.

 

The only source I'm aware of is helminc.com but I believe they are only USDM/CDM. Also they only have hard copies up to 2011 as I believe Honda went to their own service site from 2012 on and no longer provided hard copies.

Now it might be possible there is a EU version of the Honda Service site like there is for the US and CDM markets which is https://techinfo.honda.com but I'm not sure. You have to pay for day/week/annual pass but they do provide all manual pages the Honda Techs use for all the vehicles in the CDM/USDM markets.

You might try asking your dealership if there is any such website for DIY'ers like https://techinfo.honda.com
