Im planning to swap a H22a in my 99 civic. I just wanted to know what suspension would be good? I want to drop my car about 1 or 1.5 what would be ok to hold the weight of the engine and would not feel very very bounce??

who's doing this swap for you first of all??

Im probably going to Progressive Racing I went to visit the shop last week end and he showed me Pics and there were some guys there with there cars. he showed me there engines and answered all my question, he was going to take me for a ride in one so i could see how it feels but there was to much snow. I liked the way they treated me and I felt confortable. so im going there

sorry for so much info:)

bbarbulo ...why does it matter? (me being curious)

as for the swap anything stiffer then stock will work for it...ask the guys that make springs (call h and r or ground controls) they will know

It matters cuz of the nature of the question... if he said he was attempting it alone, I would have not responded anymore. Just find that ppl like that (esp with that kind of username) ask questions with no real intentions in mind, that's all. But since he's having it done ... the question is legit.

Let us look at the dynamics of the car now.... The weight distribution will be altered, no doubt. Let's assume you're adding 100 lbs... First of all, move the battery to the trunk. If you can do without A/C, remove that too.... (I'm not even sure if you can keep the A/C with an H22 swap :shrugs: ). Also get a Benen Industries hard bar (front bumper re-bar replacement, saving you 30 lbs!!!), so now, the H22A is a little more bearable. Now...you want the front to resist side to side weight transfer to it, else it will slide around like a pig in mud...but at the same time, we know that the stiffer end of the car will hit the guard rail first. So you don't want too stiff, but just right. That being said, I'd use H&R Sport Integra rates all around. It ought to compensate somewhat for the extra weight, but not be so stiff that it will cause extreme handling dynamics. Unfortunately, from there on, you'll have to experiment with sway bar combinations to return the car to some sort of civilized balance. Also consider some Z-10 radius rods for your poor poor car. I'd use a Type R front sway bar, and a USDM Si rear sway bar to start off...then change the rear as appropriate. Personally, I think this is such a departure from what Honda intended, that you will never have the car feel like it's a Honda. It's almost a faux par. In summary, relatively soft fronts, relatively hard rears...with a stiff front sway bar, and a soft rear sway bar.

The user name is what my wife calls me so I went with it. I am doing the swap the first two weeks of May. I just wanted to know what suspension and things would be good so i can buy them and have them put on the time of the swap.

What shocks do you have on now?? Those springs should be combined with some really heavy duty shocks. Koni and Bilstein are the ones that come to mind as being capable of the job. I do recommend consulting a tech in the field... like call progress suspension's tech line and chat with them. I can suggest things...but they have shock/spring dynos to prove it :)
