I've come across a 4th generation 1000+rwhp Supra with a big single turbo conversion, stock rear end, stock transmission, and Nitto drag radials. After repeated trips to the dragstrip, we expected the rear end/factory torsen LSD to give up the ghost first but rather, the car insists on killing the factory engine mounts. We upgraded to polyurethane engine mounts and these are getting killed as well. What is a good aftermarket alternative to hold all this power?
Oh yeah... do you know what a 400, 750 and 1000 hp Supra all have in common?
They all run 12's. :D
It depends what you want to do, you can get solid Billet Aluminum motor mounts from BIC Performance as well as polyurethane mounts. Polyurethane have more NVH (noise, vibration, harshness) over the stock motor mounts, but much less than full solid mounts.
