You will need a OBD 1 ecu, since your car is a 95. 96 and up came with obd 2. You can still use OBD2, but you have to get a conversion thing (not sure what its called), so its easier to use OBD1. As for the Head you can use i think any vtec head, B18c head, b16 head, and b17 head. With a b16 head, your OEM LS headers will bolt right up and maybe the manifold too. HOWEVER, if u want it done right, then go get some gsr or type r pistons and rods and maybe a crank too. You might want to change the OIL pump and water pump too. ALSO you need to take the block to a machine shop, have them hone it, resurface the head, tap the head for oil line and thread a hole for a KNOCK SENSOR.
