Confirming that this is the turbo...

[LMFK7]

Kind of confused and just wanting to confirm that what i have circled is the turbo for the 1.5?

Yeah that’s half of it

Under the heat shield next to your circle

You circled the intake side of the turbo also called compressor housing, inside is the compressor wheel. It takes ambient (filtered) air and pumps it to the intake side of the engine- there is piping and an intercooler btw the turbo and the engine air intake.
The compressor wheel is connected to the turbine wheel via a shaft. The turbine wheel is driven by the exhaust gas and it is housed in the turbine housing, which in your picture is under the heat shield.
The exhaust side (the turbine + housing ) is bolted to the muffler looking thing in your picture - that is the CAT/ Catalytic converter.

P.S.-edit: ... in the picture that you circled, you see two pipes/tubes that go to the center of the turbo (houses the turbo shaft bearing), many think those pipes are for oil, but those pipes bring engine coolant to the turbo.

So our turbo is cooled with coolant and not oil? Is this the reason why i don't see anything in the owners manual to cool down the engine after a drive? Or is it still advisable to idle the car for a bit before shutting down.

That's correct. Coolant continues to circulate through a thermal driving head/heat syphon effect. This is pretty widely adopted now-a-days, though I can't speak for all car manufacturers. I know Nissan adopted it on their 300zxs in 1985.

oil and coolant, both cools it.
If you are just slowing down after drag racing someone, you may want to idle for a minute,
otherwise you don't need to.

Drag racing? oh no no no. I'm a granny shifting, not double clutching kind of guy.

Well then...just shut it off when you reach your destination. No need to waste gasoline to idle it.

Sorry for reviving an old thread, but
Where does the turbo gets air? I mean it looks like the turbo is fully covered by heat shield and/or other parts.

it makes me wonder where? Where does it sucks air for boost? Why? How?

Here's my attempt . I may have cut into the hot side of the turbo

If thats true then im glad! Lol because i install a turbo blanket today and im worried i might block the airway.

thank you!
