Those groovy engine dampers
#7
I'm just gonna get an ebay one and make it fit around the turbo. If it doesnt work, I can move on to progressively more expensive and complicated solutions.
My hunch is that putting a brace directly opposed to the engine's movement at the place of greatest angular momentum will have the greatest likelihood of fixing the problem. All the other solutions seem to offer marginal improvements in stiffness that are very close to the axis of rotation.
If the ebay brace doesnt work, I will probably do the MS mounts next, followed by the okayama tranny brace and then the FM chassis brace.

The Okuyama tranny brace helps a bit...but not like doing the Beatrush rear brace will.
If you replaced the soft rubber mounts on the Okuyama with something of a higher durometer you would probably be in good shape.

Sounds like it may be sold out for now.
Here is the Okuyama front lower.

These guys ship really fast. I would hold off on both of these until you do the Mazdaspeed mounts though.

Yes. They make a nice difference on their own. Even better when paired with the diff mounts. You won't get that shifter to stay in one place though untill you eliminate the powerplant frame and hard mount the tranny. The Mazdaspeed mounts are a great compromise.
You could look into these too.

I have never heard of anyone actually having a set though. Kinda expensive

I was making nowhere the power that you are. Rob at Flipside had the same issue once he got near the 200 whp mark and ended up eliminating the power plant frame altogether and building a front mount for the rear diff and hard mounted the transmission. It is the best shifting Miata I have ever driven. Its pretty loud with all the gear noise being transmitted right into the cabin.
