Why are they so different?

This is the EX rear mount for a 5 SPD

and this is the one from the LX rear mount 5 SPD

im going to assume the ex is a little stiffer. it is a 4 bolt mount and the lx is a 3 bolt.

 

why are the shapes so different? they don't seem to even be compatible.. what connects to them thats different between the engines or heads?

 

the mounting location etc is all the same it is just that mount that is different. you have to know if you have a three bolt or 4 bolt. you cannot interchange them.

 

well heres the thing. I have a EX head and apparently an EX mount.. im just wondering what mounts to it? Is it part of the intake manifold? They both aren't on my car yet.. i have the stock f22b2 with a stock mount for it. I was just wondering for when i go to swap

 

there is no mount for the head it connects to the block and transmission in the rear. you need to look at the current mount to see if it is a 3 bolt or 4. then get the correct one. you are making this a lot harder than it actually is. pick up a haynes or chilton manual

 

no im not really. i want to swap my head from a non vtec to a vtec head, and im wondering why the mounts are different and if im going to run into any problems. I have both mounts, i don't know why they are different, hence why im asking.

 

the ex is supposedly some fluid controlled bullshit where the others are just a standard motor mount.

 

get the one that is for you chasis. this is not rocket science. only one of them will work.

 

Like he said get the one that fits. I will tell you the first one is air controlled. It gets stiffer at a certain rpm. I have it in my automatic 93 Lx. It has a vacuum line running to it. I can tell you my car vibrates like a bich when its at idles.

 

okay, im not sure what people are not understanding. I have a stock f22b2 that came in the car thats an LX with the original motor mount. I am swapping my head soon to a b1 head, which is from the EX as we know, and i have the motor mount for the EX. My car is 5 spd, all i am asking is why they are different. One has a v notch in it and the other does not. Just wondering why they are so different. Not sure why its so hard to get? maybe im not explaining it well enough, or there isn't a difference i'd notice. Are the through bolt holes in the same location?

 

The reason im asking is because i don't want to start and half way through realize i need something else.

 

It shouldn't matter which mount you use because I have a 94 EX that was AT, and when I converted to 5speed I used a DX rear motor mount and It fit perfectly fine and I had no problems. I believe only AT rear mounts are air controlled. But If your still un sure then just get the mount for your car

 

if you have an LX then you need an LX mount, you swapping heads has nothing to do with what mounts you need. you do not need an EX mount. and there is a big difference in the 2. the ex sits higher and is bigger. the lx sits lower and uses 3 bolts to hold it down.

 

The metal bracket on the engine that connects to the mounts are different also. If you use a big 4 bolt EX mount, you need the EX bracket. If you use the LX/DX mount, you need the LX/DX bracket.

 

^^oh yah I forgot to mention that I'm also using the DX Bracket too

 

plus if your swapping heads then why would you even need to switch the mounts?!?! what ever mount your using now will be fine.

 

well i was going to swap them because the other 3 are new from my motor swap but i ended up getting the EX one somehow i guess. Thats why i was confused, i think i was shipped the wrong set. I will get the LX one for when i swap my head, i'll have more room in there to get to the rear and change it to a new one too.

Thanks for clearing it up
