Hey there,
What do you think of the vid? adding a silicone at the engine mount to make it stiffer?

You'll get a bit more responsive engine input, but it'll also transmit more vibrations to the cabin and chassis.

This trick works, but you want to make sure that the silicone you're using sets up fairly hard. If it's soft, it will just squeeze out the sides and eventually fall apart. The good stuff is a 2-part mix. I've heard that "Shoe Goo" also works pretty well.
Also, you want something that's got good adhesion and either start with new mounts, or REALLY clean the old ones so that it sticks in place.
You can achieve a similar effect (throttle response) without adding as much vibration by fitting a "torque strut" to resist rotation of the engine. (there's already one at the bottom of the engine, but it's got a lot of rubber in it) I had one mounted from the upper engine mount to the strut tower for a while. It was just a piece I had laying in the garage from a Miata. I liked it a lot until the engine vibration took its toll and broke one of the brackets. You get a LOT of noise doing that because it, a fairly rigid mount straight into the firewall. So, it resonates and sort of amplifies engine noise. It actually sounded kinda cool if you're into that sort of thing. Just a low growl, sort of like intake noise.
Something like This, but you'd have to fabricate brackets for it.
Simplify and add lightness.
