Yeah, it will definitely settle down the engine movement... just like a set of aftermarket mounts would. But I would expect it to translate a lot of that absorbed force into the cabin in the form of buzz/vibration (just like aftermarket mounts do).
They're decently cheap, so if you can figure out a mounting method I'd say its worth a try. I sold mine for nearly what I bought it for new, so no skin off my back.

The best way to set those up is to not be so tight that they transmit all that vibration, the job of these is to limit the added motor twist under acceleration, so run it a bit lose so its more or less "floating" when engine is at idle when there is no twist. I’ve had the best luck running them that way. I’ve tried cranking the shit out of them too so they are real tight at idle and all they do it’s transmit all the engine vibration through the chassis because there is no forgiveness at all. The motor needs to move a little or things are going to start cracking/breaking from the vibration, or at the very least annoy the shit out of you.
Thanks
It's not the new turbo engine, but 2-liter NA. 143hp. Surprisingly quick and fun considering the power. 
Thanks! I think it could serve me well as a daily driver.
And it use a lot less fuel than the old 525ix I've had as a winter beater/daily now.

So for 400-450whp turbo set up, on an 03 F20c with 160k miles, would you be worried about the stock valve springs / guides / seats? I changed the retainers about 10k miles ago, and will be putting in a new short block this week. I haven't had any issues in the head, and I know normally stock would be sufficient, but with the mileage, are these things you would think are worth the hassle of replacing?
