Dog Bone Engine Mounts

Subject: Dog Bone Engine Mounts Thu Mar 20, 2014 12:31 pm

Has anyone ever tried adapting the Dog Bone engine mounts off of a GTP to a Rivi? I would think that it would eliminate the need for filling the engine mounts or making hockey puck mounts. Could even eliminate that stupid mount that goes through the belt.

You can't. There isn't an upper support to mount them too.

Do you mean the support on the radiator shroud or the motor? Or do you mean there's no bolt holes on the motor for the mount? Either way I was thinking of pulling the whole assembly out of a GTP, drilling the holes in the radiator shroud, and bolting everything up. Looks like it would be pretty straightforward.

The upper radiator shroud on the Riv is not metal. That's not a good idea.

Really? I could have sworn it was metal. Will check tomorrow when I'm changing my oil.

Even if it was metal, it has zero frame/chassis support. Notice that it only has bolts on the outer edges holding it down. It's just a decorative "cap" for the Radiator/Condenser.

Welp, nevermind then. Oh well....

It certainly wasn't a bad thought. I brainstorm ideas of ways to tie this engine down all the time.

There's just nothing underneath that thing to support engine torque...

I knew there wasn't a tremendous amount under it, but I figured the GTP's was similar. Off to go find someone doing a radiator replacement in that to see what supports it (just out of curiosity).

It looks like it should be, but there's not much there. Look at the bracing to support the hood latch.

In a GTP that's a structural piece of metal. Not on the Riv.

That's exactly what I'm seeing. I just started a video on a radiator replacement on a GTP. Strange how they designed the supports so differently for the same engine.

Well, the Riv wasn't designed as a "sports" car like the Grand Prix. It's supposed to be mushy and cloud-like. I'm sure they weren't expecting a bunch of idiots like us to be modding the hell outta these things lol.

which is why we:

- install strut tower brace
- fill engine mounts
- replace OE front struts with almost anything (kyb, Monroe, Gabriel, etc) firmer
- obsess about springs etc.
