Its powered by a 1.8 SOHC engine, the non turbo version https://en.wikipedia.org/wiki/GM_Family_II_engine#LT2
According to this article, the 1.8 (84 hp/107 lb-ft) was replaced by the 2.0 (96 hp/118 lb-ft) in 1987. A neat little car to have if you could make it run right. Supposedly at $300 scrap value, you'd only be risking $200 on the mechanicals, but remember it's near Philly -- expect rust.
Maybe Squire, but there are always surprises out there. When I bought my 69 Merc on 2001, it was a NEPA car all its life (Shenandoah PA) but it was always garaged, so amazingly, it only had rust behind the gas filler door by the neck that I had to repair. I still have many old car friends up in that area and am still surprised on some of the cars they find. I think garaging is the key, and using the car sparingly in the winter months. Just last year I was up visiting a friend up there in the summer near Shamokin, PA and on his street there was a mint early 80's Cavalier "Type 10" (whatever that means) hatchback parked on the street. As a FoMoCo and Mopar guy I said to my friend it must have been hermetically sealed - then we drove down a street or two and he showed me a super nice 76 Caprice sedan, but I think these were fair weather cars. When I lived up there, there was always rusty cars, but when I went up to Buffalo, oh my, that's rust on a whole 'nother level then the Philly area.
I spent a decade in Philly. Never had a rust problem Roads were deiced with some kind of coal slag. Nothing like here in NY or back in Canada.
Yep, ash from coal furnaces - kinda feels like putting granola down! Works pretty good and there was always a healthy supply of it.....
