Identifying an engine?

[Toaster Pilot]

I have an old Saxo which should have a 1.1 HFX engine in. It's been replaced aparrently with a 1.4 but I gather they look very similar (and it says HFX 1.1 on it in scrapyard paint....)

The engine number is clearly visible - is there any way I can identify which it is based on that? Can't find any other ID markings on it apart from "Z05"

Yeah I thought there would be a tag with the engine code - my A6 1.8T has a tag saying "APU" next to the front lifting eye

From multiple sources, motor factors etc, HFX refers to the TU1JP 1.1 engine - the VIN even contains "HFX "

That's what is supposed to be in there from the factory - now how do I identify a TU1 vs TU3...

This looks promising although the diagrams show a spin on type oil filter and it has a cartridge type.

Like the using oil to determine capacity method above too - will do that if I can't find any more markings!
