RE: Whats all needed for a Zc swap?
I would suggest just buying the zc engine with the zc tranny. The 4spd (if you have an std)will hook up without a problem but you will be sorry you spent the time doing it. If you have an si stick with it and save your money. Dx is your call, but if its slipping at all or even needs a new clutch get the zc. Most engine/tranny packages come with the intermediate shaft, but make sure first. If you are using the zc tranny you will need 90-93 integra axles and if std hubs from the same year civic dx, or si(If you can buy the knuckles with them so you dont have to get them pushed in). I would suggest shopping through the forum classifieds(4gcivic.com, honda-tech.com, clubcivic.com, hondaforums.com), ebay, junkyards, and of course hondaautomotiveparts.com. Yeah the zc dohc does get about 130hp, but remember its at the flywheel not the wheel, so anyone thinking that they are going to hit 13's with a couple bolt-ons and no sweat should think again. But, coming from an std like I am and doubling your hp with the swap, on a car that needs the engine replaced soon anyhow, priceless. Also this is an easy swap but includes a dpfi to mpfi swap(dual port fuel injection-multi port fuel injection). You may want to get the si throttle cable(same year) so you dont have to fab one up. Ecus can be pm7, pm6, or pg7. pm7 from an integra is the most powerful. pm6 (same years)(from I believe civic is for economy. and the pg7 in for the zc and the best all around ecu. When finding one stay in your era, for obd reasons, it will make the swap easier. I think that about covers it. Check out those sites. Good luck.
Next time you have a question write your year, make, model, and trimline, along with the engine or tranny's. There are so many configurations out there its insane.
