Read the archive post about the cluster face swapping, it basically goes that a turbo cluster will install as an upgrade, but for a turbo car it will not work to install a non-turbo CSM cluster.
It makes more sense when you see the scans of the cluster faces, and the gearing/readouts they have listed. This way you know which one swap over. I've installed a 240 KMH AUS face into my 240 KMH turbo cluster, direct and 100% accurate minus the needle removal and re-installation.
I have to upload new copies of the scans to a new archive location.
I'm also thinking that matching your top speed (preferred if mph to swap to mph, KMH with KMH), then it will match. Same thinking for your tachometer, highest RPM matching and you are good there too. This is from memory, so I'll have to back this up.
