To swap a B18B or B20 into an Ek you need; 99-00 Si rear trans mount bracket, Si driver side mount bracket(bolts to the block), Del Sol Vtec AC mount bracket, 94-01 Integra or 99-00 Si shifter, use all stock civic rubber motor mounts. Wiring may be as simple as plugging everying in and extending any needed sensors, for LX and DX modles. EX will all plug right in and is wired for vtec if you are going LS/vtec. The HX modle needs a bit more wiring, 5 wire HX o2 to B series 4 wire o2, HX 3 wire CFS to B series 2 wire CFS. Plus removing al the extra un needed HX EGR wiring. Dont worry about the starters they all will work just the same, use the one for the motor and trans you use(if using LS use the one from the LS ect). Same with the Alternator just use the one for your motor. The civic's plug will plg right in.
