Would this be great for a 335i N54 with heavy performance mods?

Absolutely, I run it in my Shelby GT350

Can i use it on a 2005 bmw 545i?

The 2005 545i uses 5w30 or 0w40 when in temperatures over 50 degrees F.

Is this good for an old/worn opel zafira b 1.9 cdti, or is it a bit too thick for the system?

I’m sorry I don’t know about your particular car however it went into my 2020 Shelby gt 350 easily, as it is the required viscosity. The oil was not thick like the old 20/50 weight oil it was actually easy to pour. The oil pressure typically runs over 100 lbs in the Shelby if that helps.
