PLEASE HELP me Identify this engine!

'97 Chevy Metro LSI Hatchback 1.3L 4Cyl Auto Trans,

I bought this Geo it has had the engine replaced before I got it and I'm not sure what the engine is from, I have a manual but there is a lot of things on the engine that just don't look like what is in the manual.

I don't know where the MAP sensor is on this engine.

So if anyone can tell me how to Identify this engine or can tell what it is from the following photos please let me know.

looks like a standard 1.3 metro/swift SOHC motor to me. the map sensor is mounted on firewall next to wiper motor. see that white round thing in the vacuum line by wiper motor? that is the hose going to the map sensor
