As part of performance mods, have removed the smog pump, associated brackets, the crossover supply pipe, along with vacuum hoses,
& the single groove wp pulley on quite a few '80 Turbo cars. The '81 Turbo's (except Export cars) had all the C4 crap on them, and the smog pump & supply line are different.

I mentioned a turbo heat shield too, but thats doesnt look like one from a turbo 301. Heres a pic of a turbo heat shield, its shaped different and slightly different mount hole arrangement.
Thats a heat shield of some sort but not from any 80/81 turbo Ive seen. Might be like nuclear said and not even from/for your car?
I removed the emissions/smog pump stuff on my 81 turbo too, but instead of eliminating the parts totally, I kept everything installed for a stock look or for a future owner to put it all back if desired. I just gutted the smog pump then let it act as a free spinning pulley in order to keep the stock belts.
