no its not completely different ... you use a obd0 pr3 ecu , obd0 b16a dist and injectors , obdo alt and extend the coolant sensor wires from the back of the block (on the stock harness) to the water neck on the gsr .... you dont use the sensor on the crank. then all the same steps as wiring a dx to sir or si to sir ....very easy ..... and if your friend is doing it then why doesnt he already know what he is doing ?????
