Iâ€™m in need of technical advice regarding what to do with a D15B8 engine that I just purchased to replace a worn-out D15B7 engine in a â€™92 Civic LX. Iâ€™m very new to Honda engines and must admit Iâ€™m dazed and confused by all of the different engines and combinations available for swapping. The engine I just purchased was being sold as a D15B7, and I find out after purchasing it that itâ€™s actually a D15B8. I am disappointed to learn that it originally came from a Civic CX, and has only 70 HP vs. the 102 HP of the original engine in my Civic. Several questions: 1.) Although I know this engine will actually fit into my Civic, is it going to be so underpowered that Iâ€™ll be wishing Iâ€™d used another D15B7 or something else? Iâ€™m not really so concerned about having a powerful engine, but I donâ€™t want to feel like Iâ€™m driving a Geo Metro. 2.) Will this D15B8 engine bolt up and work properly with the automatic transmission thatâ€™s in my Civic?(it's currently attached to a 5-speed) 3.) Are there any parts on the D15B7 engine that will swap onto the D15B8 that will help increase the HP? Thanks for any and all help.
