Default Smog equipment
Big favour to ask. I am building a monster and it is based on a 93 coupe. The local regs state that the emissions must comply with standard equip for that model year. My prob is that that I bought it without an engine so I'm guessing based on my 944. The questions are; 1. Is the OS sensor before the cat and did the 93 have a sensor before and behind the cat. 2. Did the 93 have an EGR and or an air pump. Anything you folks can add would be appreciated.

O2 sensor is before the Catalyst. There is no airpump but a checkvalve in the emissions circuit.
What kind of intake are you using?

There is crank case ventilation, but it gets recirculated back into the intake. Its part of the oil filler unit.
