Available in standard form with power of upto 325bhp (depending on the year), so this goes to show the tuning potential of the Z3M. From this you can increase the power from anywhere between 357.5bhp to 552.5bhp but this is far out of the reach of your local part store.
You will need some extensive work on the engine block, gas flowing, porting, 3 angle valve job, fast road cams, a remap, full balance and blueprint and even then you will need to add some pretty serious forced induction upgrades.
An engine swap with that from the 325bhp Z3M Coupe will give a massive power gain and provide a better base to work from. The more powerful Z3Ms respond exceptionally well to tuning mods. Your first engine modifications for your Z3M should be an induction kit, sports exhaust and fuel boost valve.
The modification that gives the biggest power gain on your car would be a fast road cam. Getting better flow through the head of the engine would reward your Z3M with more power. So get the engine head polished and ported.

The forced induction Z3Ms are around with some impressive Turbo and supercharger conversions being done. These give impressive power gains over standard but require a lot of effort to get working properly. If you have a turbo or supercharger get the intercooler uprated for even more power.
