ok I have a 6th gen Civic myself I am doing the H22 swap in. First of all I dont reccomend this swap for a first timer. If u are brave enough to do it then listen up.

things u will need:
-Hasport mount kit
-Hasport modified rear tranny bracket
-P13 ECU, or would reccomend the P72 ECU with Hondata mod
-H22A engine, tranny
-if u go with the 92-96 H22A's then u will need the firewall mounted map sensor
-OBD2 to OBD1 conversion adapter (if u want OBD1 obviously)
-92-96 engines will need the injector resistor box
-custom axles(1990+ integra axles/1990-93 Accord intermediate shafts and left inner joint), or u can go the easy way (but expensive) and get driveshaftshop modified stage 1 axles like I did.
-Prelude shifter cables
-Prelude shifter box
-Prelude upper and lower radiator hoses or 1992 Integra LS upper radiator hose or 1994 Del Sol VTEC lower radiator hose (all these will work or so I am told)


things that need to be done:
-lots of modification to wiring harness
-cut holes in chassis for shifter cables and shifter box assembly
-extend fuel line to reach fuel rail
-radiator fan shroud triming or get a slimline type of fan
-modify exhaust cuz it will not bolt up

I think thats it as far as the things u will need... check this link out for more specifics http://www.honda-tech.com/zerothread?id=650329&page=1

common questions and reccomendations...
-I found a company that makes aftermarket hybrid headers just for the H22 swap in a civic. http://www.imagineengineering.com. They are on a huge waiting list. About 4 to 6 weeks so definately get one ordered as soon as possible.
-Spring rates and chassis stiffening are the key to making these front heavy Civics handle. Don't believe any losers that say that its too heavy for the chassis and cant handle blah blah blah. They just dont know what they are talking about. Sure for a street car the H22'd Civic can handle pretty well. It will never be no autocross ripper. If u want autocross stay with the D series. As far as the spring rates goes no one really knows for sure. Some people say go with the prelude spring rates or things like that. I actually called Ground Control. They have a hybrid coilover set for Civics. Its for B series engines. The B series is only like 70 or 80 pounds lighter than the H22 so its very comparably. Their kit is a 400F/300R. I am going with 350's in the rear just for the bit of added weight the H22's have over the B's. I will let everyone know how it handles when I get it all together.
-As far as shock tower bars goes well I personally believe the stiffer the better. There is no better bars on the market than Carbing strut bars. check them out. Beware though they are expensive! http://www.passwordjdm.com
-Cold Air intakes. Well some people have used the Prelude CAI. I ordered the ITR intake (cuz it has the same diameter piping as the Prelude one). Obviously the Civic and integra chassis's are similar so thats why I choose the ITR one. Either CAI will requre modifing.
-As far as exhaust goes 2.5 inch is definately the reccomended size for the H22A's. No one sells a 2.5 for the Civic. U can go with a 2.25" one like Magnaflow or Thermal or companies like that if u like. Personally I believe a universal cat on the imagine engineering header, with a custom built 2.5" mandrel bent exhaust (from a local shop) is prolly the best way to go. Also for universal high flow mufflers I would go with Magnaflow. They are the best priced high flow mufflers that I have found with straight thru design. They are a quality company which makes good power on the dynos I have seen with their exhausts on . They are around 100 dollars for the universal mufflers.
-Ohh yeah dont forget to upgrade the anti sway bars for the front and get a kit for the rear. As far as sway bars goes I have had the Skunk2's b4 and I was not happy with them. I have already installed the Suspension Techniques ones and their quality is off the chain and they dont rub on my exhaust!!
