Turbo motor passed the smog test. Glad I left the cat on for the visual.

It depends on how far north you are. Historically we haven't salted the roads, so most of the rust comes from cars parked in fields with wet grass. But recently as the wintertime temps have increased, they've started using a salt solution on the roads here when the temps are hovering around freezing. Once it drops down below 25 they stop salting.

Cool. When I moved to Arizona I thought I’d gone to heaven with all the rust free steel.

“Ray Charles with his feet” booger welds for the new wide-band hook up. Sigh.

The dyno sniffer said that my AF is OK but, since I have the gauge, what the heck.

“Transmission” leak appears to be blow-back from an engine oil leak. It never ends...

Isn't that a little close to the turbo outlet?

Yes.

See page 10

"Mount the O2 sensor in the exhaust system at least 18 inches downstream from the exhaust port"

Going in I thought we would mount it under the car but the muffler guys said it should be placed ahead of the cat. I don’t know to what extent the cat effects the reading. As I recall, the efi O2 threads into the bottom of the manifold before the turbo. Any advice would be appreciated.

You are going to burn up your wideband. Where is your cat located? stock b21ft location?

Doubt it. That engine is putting out relatively little heat.

You need to be before the cat. If you have it after the cat (assuming the cat isn't a gutted shell), you will have erroneous readings. https://www.youtube.com/watch?time_c...&v=HADOcrcMikA

All modern vehicles have pre and post cat O2 sensors.

I had mine in that spot for a long time without issue. Just leave it until you upgrade the whole exhaust.
