placement of O2 sensor on 3.0 SC
I am doing a ITB project on a 3.0 SC with stock crossover exhaust. I want to put an O2 on each bank. What is my best location and method?

The later SC model had an O2 sensor. Look at the parts diagram (in the PET) for Porsche's location? I think they only had a single sensor after the collector for the two sides.
I think the stock crossover exhaust is going to choke off the gains from the ITB setup? '78 SC/w EFI and SSIs |

4-6" inches past the three tube collector on each exhaust bank.
15-40* degrees of angle from horizontal , make sure you will be able to remove the exhaust valve cover for each placement . Not a tough job , just think about placement Mark it an drill it, then weld in the bung Ian

Thanks Ian. What type of metal am I working with? It looks like stainless in those sections.
