Please help - engine identification

Hello, I have just bought a 1980 Mustang with a non-factory engine.
Can anyone please help me identify what type engine it is?
If you see anything "wrong" about the engine or if you see things that might need attention soon, please tell me.
(I was told it's a 2.3l Turbo, but I can't locate the turbocharger anywhere so i have serious doubts
