Have you been in an NSX before? My friend has one. Unless you plan to make a custom cover for the center console or modify the existing one, don't even start the empeg install.

For a nice fit and finish you'll want to measure everything out, take out the center console cover, remove the factory head and figure out how you want to proceed.

There is at least one replacement center cover/frame available somewhere that might be suitable for mounting the empeg. I'm sure you would be able to find out at NSX Prime. I know my friend has seen people talking about it before. It's definitely upwards of US$100 (probably more than $200).
