A lot of wheel hop problems can be traced back to the radius rod bushings in the front crossmember. The stock ones are really soft, and allow for quite a bit of up-n-down AND fore-n-aft movement of the suspension (to help keep the ride softer). Stiffer radius rod bushings can do wonders. Davens installed urethane bushings in his front suspension when he did his B18b install (w/Honda LSD), and he was having some bad problems with wheel hop. He installed a JimFab front crossmember, and the problems VANISHED. I think the JimFab might be a bit of overkill, but it definitely worked. If it were me (cheapo that I am), I'd try to locate some urethane radius rod bushings first, and look to replacing the entire front crossmember as a last resort.
