u need the wiering harness, most likely an ecu, and i think only a little time. i think thats it but i could be wrong

Then you'll need to then run wiring for VTEC solenoid and buy a pressure switch or bypass it because the JDM \D15B doesn't come with one. Swap over the block mount on the timing belt side from your D15B over to the new D15B. Extend the wiring for the fan switch from the back of the block to the thermostat housing. Get a OBD0-1 distributor and ECU adapter to run a P28 OBD1 ECU or comprable. Run wiring for 4 wire oxygen sensor.

 

dosen't he also have to do dpfi to mpfi conversion
