Ive heard they are, it's an energy suspension mount, you would have an urethane mount on both the front and back, and a side mount, I used my dog bone arm to mount my catch can. I also replaced the big end of it with a solid aluminum mount. I plan on turning a small end out of urethane or doing the trick of filling it with urethane
Re: yay! Finally broke something racing!!!
while we're on the subject of mounts, torque dampener? basically a shock absorber, right? I had a buddy in high school who had a saturn, he broke the upper rear mount and was too cheap to spend 40 dollars on one, so he put in a steel chain ha bolted it to his firewall. I never looked at it after a week or so, so I couldn't tell you if it held up.

That wouldn't work on these cars since the whole point of the torque dampener is to keep the motor from torquing towards the firewall. not away from it. In theory with beefy enough motor mounts you don't need it at all.

those energy suspension mounts also have an interlock, the top of the mount can't separate from the bottom. The only issue with getting rid of the dog bone, is the engine is still going to move under acceleration, this is movement that is wasted not turning the wheels, the wheels don't want to move so the engine twists instead, no mount by itself is going to stop this. I noticed a big difference going to the partly solid dog bone, the engine can move somewhat but not nearly as much, I definitely think you will have far less engine movement with it there and if you do the urethane conversion

Honestly I haven't had any problems with the motor torquing. I have all of the mounts including the dogbone bushings filled with poly, and they're quite strong now. I just hate how the engine sits cockeyed. Plus it'd be nice to have cheap, easily replaceable poly mounts.
I guess it will wait to be seen until after I get the energy suspension mounts. I'll try it both ways, and if I don't notice a big difference in engine movement I'll delete it. Otherwise it stays.

he has those mounts available, the thread shows the energy suspension mount part number to get that bolts to them, the mounts usually go for about 30 each, the energy suspension part,but will probably outlast the car

All the DX Accords should use the shorter front mount with the stamped engine bracket. You have the cast bracket which is used with the taller front mount, so I'm guessing you have the taller front mount as well. That would be why the engine sits wrong.
The mount brackets I made along with the GM tranny mount are designed around the shorter stock mounts, so they will work for both the front and rear mount. They should also work on cars with the taller front mount if you add a spacer or switch to the stamped engine bracket. I can't absolutely confirm it will work but I'm pretty sure it will.
The GM poly mounts are about as close as you can get to solid mounts without actually being solid. You can remove the torque arm and still have virtually no engine wind up. That was my motivation for designing them in the first place.

Nice! I'll be hitting you up in a couple of weeks for mount brackets then.
Re: yay! Finally broke something racing!!!
make any progress on your trackcar? I officially have a rod knock, the accords been sitting all week now. workin on a couple swap ideas, maybe even using this one for parts :( Only for her twin though.
