I totally agree with f87source. It’s not just a cutting operation
Here is a quick outline sketch just showing the difference in size and location of things. And then there are physical lines in the way too.
So below is just for fun and nothing else.
Inner line is original M2 hpfp
Outerline is b58 Supra hpfp.
Lines on the outline is connector orientation. Big box is electrical connector.
