You cut the fenders under the molding and ran the Civic lower portion? Correct radiator support? It should all bolt together, and a CRX nose holds a larger IC without sawzall action.

How much larger, approx? I've got a 12 inch tall core on the hatch that's way too flashy for me, because I couldn't fit it under the bumper without having it stick out below. I'm in the process of getting a CRX, was hoping I could get away with the 12 inch, if not, I will cut it down and re-weld the end tanks.

12 inch is borderline, 11 inch is doable, depending on thickness. I had 24X11X4 and it pushed the bottom of the bumper out a hair... if it had only been 3" it would have tucked sweet.

CRX bumper immediately swoops forward. Hatchcrap have the little piece that runs under the headlights, and then the bumper cover tucks under that so it eats up even more room, and you end up losing an inch or a little more height with all that BS.

You have a good point with that. My evo8 fmic sticks out from underneath about 1 1/2" inches righ now. I fucked up originally...I cut and welded the bottom pieces from the old hatch fenders to the crx ones...they fit like a dream. Problem came in with the radiator support...crx one was pretty hashed from a previous accident, so all I had was the original hatch piece. I don't even have that big metal bumper support in there anymore, so I'm pretty much fucked if I hit something head on.
