I've had a 95 Prelude for about 5 years now, 2 years ago i swapped out the H23 and put in a USDM H22.. pretty easy to swap out, just had to change the ECU and harness.

I'm new to the boards since I just bought a civic, I've been a long time member of PreludeOnline.com. My Prelude is pretty busted up since I got rear-ended on the interstate on the way to Carlisle in 2004. I've been driving it still with a green rear bumper on it haha, cracked hood/front bumper (all aftermarket.) So now i have a civic that has 175k miles on, and a H22 just sitting here, taunting me.

So basically my question is, how extensive is a USDM H22a1 swap into a 98 Civic EX? I've searched the boards and found alot of "its hard", but nothing in detail. I probably won't end up doing the swap because it is probably very time consuming and also very pricey. But I was just curious if anyone could give me some details about the swap, or a link to a write up somewhere. Thanks in advance and I look foward to chatting with all of you.

 

All I know you need is new motor mounts, axels, and shift linkages, ecu and all that stuff. I don't know everything that is needed tho.
