what obd is the swap, if its obd1 then you need an obd2-obd1jumper harness for the ecu. go for a obd2 b18b itll save you on getting a jumper harness. also you need LS axles and the halfshaft, most swaps come with the halfshaft, but find out for sure. Motor Mounts. ECU. Wiring Harness. If your transmission doesn't come with the fork or the slave cylinder, then you'll need those as well. Theres tons of info out there. I did an LS swap in my 92 hatch. Have fun. http://motorswaps.tripod.com/id2.html
