Default CX7 with Ranger timing gears

My uncle has an 07 CX7 turbo with questionable timing chain slack at 80,000 miles.

I believe the CX7's had variable timing correct?
If so, then according to this post from this thread he can swap the MX5 timing gears and use the Ranger timing chain.

Or, if the CX7 is not VVT then he should be able to swap straight to the Ranger stuff, right?

This should have no effect on timing covers should it?

seems like it would work to me, don't forget you will have to swap the crank gear which i think will make you have to switch oil pump gear as well.

The VVT is integral to that gear right? Not something that can be bolted/unbolted? Not like a cam phaser?

The vvt cam gear is a cam phaser, you should be able to unbolt the 50 tooth cx-7 one and replace it with a 38 tooth miata one. You can not bolt a non vvt gear on a vvt cam

Ok good info. Good enough to go on for now. I guess it starts to boil down to physically having parts in hand for me/us to verify.
