the f22 b2 to b1 swap is a cake walk.. all thats needed is one wire from the new ecu you'll have to get off an ex model and a vtec intake gasket.. everything else bolts right up.. i did this swap this last weekend and it was easy.. i just have my vtec on a 12v switch till i can find a 97 ex ecu.. then it will be all comp controlled. any one know where i can find the damn ecu? also i am going to be running a turbonetics t304 hybrid with 40 shot courtesy of zex.. hope the shit holds together.. he he
