Honda Car Forum

i'm looking for something that is possible, even though it might be difficult, aka take a while to work it out. thanks a lot.please do not post any stupid or rhetorical comments. this is a honest question for a mature audience that has knowledge or experience in this arena. i am interested in a complete engine swap for this vehicle but not sure where to get started on this project. any PRODUCTIVE or POSITIVE input would be greatly appreciated. thank you...

Another 2003 honda civic LX engine. Some pretty talented engineers put that engine there and made it fit. What makes you think you're smarter or more talented than them?

I'd put a big block 454 in there.

Go with the big block 454. You may not be able to see over the engine, but everybody will be behind you anyway.

I am with you we dont need stupid questionsI would recomend you ;Try the acura gsr engineIs identic with 2007 civic SI 200hpAnd should fit in your car I hope this help you

Your best bet would be to stay with a honda motor. Since you have a '03 try to use a '03 motor or newer. I'd stay away form B-series motors just because there '01 and older and more trouble to swap than there worth into your body style civic. Your best bet would be a K-series motor. you will need motor mounts, wiring transmission cables and many other parts but would be fun in the end.
