The only other turbo I know of at that time was the Buick LaSabre 231. On the F Body, my sister had the 80 Turbo Formula, I had an 81 Turbo Trans Am. There were supposedly some turbo mustangs running around 78 - 80, never saw one. On the Fender tag it should have embossed W72. I have a 81 Bandit II Turbo Trans Am, that code was Y88 which was the special edition and you will find that on the Fender tag, usually drivers side near the cowl. And should be on the build sheet.
Maybe someone with a W30 could verify if the same held true for it. I would expect you would see W72 on the Fender tag, but not certain.
