I'm doing a swap with a 01 gsr and i'm using a type r header. Are the o2 sensors the same or do I have to use a 01 gsr o2 sensor? Also, are the o2 sensors the same for the obd1 and obd2? I'm thinking not, but need a second opinion.

 

i bet all of the obd1 o2 sensors are the same and all of the obd2 o2 sensors are the same.
