done it ..no. I'm in the process. That being said..
Ease of install. Dont know yet. But next honda tuner (Feburary/March 2003) is going to show how to do the swap. And there is a magazine that did it this month called Import Tuner, dont know if you get it. But its not hard from what ive been seeing and researching. With the hasport mounts you will have to remove the stock hatch tranny mount. With the other mounts you dont have to do that.
Pro's there is a gazillion..lol. Torque, hp, bragging rights?? lol
Cons..not much, people will bitch about the weight blahblahblah but its not a big deal. Axles breaking, those tend to be on the fault of the old mounts. The first mounts that came out hasports first gen...the mounts didnt mount the engine correctly and it made people break their axles. I recommend getting the new hasports.. thats what i got...
Keep b16 rex or go h22 hatch??? Ive ridden in both IMO the h22 is better. I love crx's so its hard for me to say that...AND i think a lot depends on how much you have to spend...
Axles. If you use the hasport mounts you can use 90 accord intermediate shaft and 90-93 axles..
Wiring.. it depends on what type of hatch you get. It doesnt seem like a wiring nightmare. YOU NEED THE RESISTOR PACK..
