I agree with Vanne.
Architecture of the engine should be the same for M3 and Z4M S54
Only difference would be engine bay sheet metal etc.
Ducting may be different due to the sheet metal.
Check out pictures of the M3 install and compare to your engine bay.
Other than that the only differences between 525 and 575 would likely be pulley size, injectors and tune.
A good tuner can advise on upgrading a 525 kit that was designed for the Z4M to a 575 or better spec.
pokeybritches immediately comes to mind.
