Name's Ben and I'm looking at a 1998 Civic HX as next project. My buddy got this D16y7 project and it is a fun build. I'll be needing as much info before we take a look at her maybe next so I'll be reading around.
Try honda-tech.com for critical info. ClubCivic.com might be worth a browse as well. Stay off Facebook pages. If you fail to heed that warning you'll soon see why I messaged that. The hx motor is a quirky little d15z1 and it's well made and thought out. Honda-tech has the best info I've seen for it yet.
