Is there much of a difference between b16 ob1 and b16 ob2 how much of a difference is there?

 

The OBD differences have to do with sensors and emission standards. You have much more freedom with OBD1 cars (and often the motors) than you do OBD2. OBD2 is a massive pain with extra things such as EVAP purge solonoid's and valves, 2nd 02 sensors, crank angle sensor, (ect). (speaking in terms of D and B series motors).

 

speaking of b16 part is there much difference? I know they are different years but how is the performance part?
