i bought a used 1991 honda crx, and im wanting to get one of the vtecs, and im just wondering how do i find out what trim of crx i have. and if that engine will fit in my crx, im pretty sure its not the si, because ive seen them before and they have the emblem or whatever on the back that says "si" but i dont know what to look for to see if its the dx or hf, any help will be much appreciated, thanks
