![Question](https://www.rx7club.com/images/icons/icon5.gif)
I recently installed a new transmission in my car along with some solid aluminum mounts. when I started it up and began driving, I noticed it sounded like I was inside a train engine or something, I can hear EVERYTHING.
I know having solid mounts will transfer more sound and vibration to the cockpit, but to what extent? It is worth noting that I feel vibration around 1500-3000 rpm (not exactly sure where) and then again at about 5000 that dies off after my rpms move past that.
Is this normal?
any info is greatly appreciated!
Thanks,
-Miles

I used to run an rb header and a 3 inch straight exhaust, and a 4 puck clutch, I am not what you would call a stickler for comfort hahaha
Thanks for the info guys!

Those things will rattle half your plastic dash pieces apart. Along with any poly mounts that are not of the double-sided design. Not bad for a racecar with all that stuff yanked. As long as all the electronics are isolated.
I don't think i need to explain how i know this...

I can hear every little gear spinning and oil slushing through the gear box.... And yes, the first time I started the car it freaked me out too. It's like getting that upgraded custom 6 speed transmission in GT5, all you hear is the gear whine : P
Upgrade to solid diff mounts and you get more mechanical tunes...

my first response to the titles was "well no ****!"
i've used factory mounts and solid mounts. I prefer my hockey pucks. above and below the frame with a through bolt design. I can adjust the mount stiffness by tightening down the bolt. used a torque wrench to keep the mounts even. and double nutted so it won't rattle loose.
I can feel all the vibration but not hear anything. very streetable.

Everyone has their own idea of what is street-able. Personally, for a street driven car, no way I would tolerate the solid mount vibration and harmonics. If you are not driving the car lots of miles it will be fun. If you are daily driving it, I bet you get tired of it pretty quickly.
Now that you can just go ahead and remove the entire interior, it won't be any louder and you can cut some serious weight. And take the passenger seat out as well because no one else will care to ride along anymore!

That was more commentary than justification.
I find it amusing that folks who abhor the idea of swapping the engine (because it's the "soul" of the car and who needs torque anyway?) think that second guessing the suspension engineers by throwing chunks of aluminum and hockey pucks in is perfectly OK.
I've never seen a hybrid "street/track" car that was very good at either...too noisy and harsh for street and not serious enough for the track, pick one and go for it.

Vin Diesel had solid mounts in his FD. Paul Walker had stock mounts in his Eclipse. Thats the main reason Vin D won, and not having solid mounts causes premature blowing of the intake manifold's welds.
