if your gonna swap engines y dont you put in the ZC. it's just as easy as swaping in the si. only with your std civic you'll have to modify the wireing harness. I also have the std civic, and plan on putting in the ZC SOON.

the only reason that im not going to get the zc is because my friend is selling me the si motor, tranny, and ecu for $200 because he is getting a vtec.

well if it were me i would wait and get the ZC that way i would have to do a swao twice, but if you plan on keeping the si in there a while there are ALL kinds of mods you can get for it.

That's cool..Si tranny, Si engine, distributor, ecu and harness...I'd buy the harness off you, however I'm a brokeass right now. Hold onto it though if you want to sell as I'll buy in a few weeks.

Your gonna need to modify the DX harness anyways. Please don't think the Si Harness swap onto the DX or Base harness...theya re completely different at the connectors and the wiring routes differently...tried it, been there.
