This thread is for those running the entire ES motor mount sets. What kind of ride quality do you get with this? I am ready to get the entire set but I want to see what I am instore for with ride quality and harshness. Any feed back please post.

The ES Motor Mounts won't effect your ride, but they do allow for more engine vibrations to enter the interior of the car. I have two of the ES Motor Mounts installed on my SE-R (the "dog-bone insert" and the rear engine mount). The driver and passanger mounts were replaced with stock Nissan units. This setup was recommended by Courtesy Nissan to minimize engine movement and retain stock like dampening of engine vibrations. The increase in vibrations are most noticeable the first two weeks after installation and seems to diminish to a reasonable level afterwards.

I also have the ES Hyperflex kit installed on my SE-R. This kit replaces all of the stock rubber bushings with polyurethane units. The biggest change I noticed with this kit was the elimination of any play and slop in the suspension. Ride quality? It's hard to say. I upgraded the suspension w/ ProKits & AGX's at the same time. If you're looking for a stock ride, stay with the stock rubber bushings.

On the contrary, the ES motor mount inserts will make your car overall louder, especially at free-way speeds in 4th or 5th gear. I think the sound is the equivalent of free-flowing exhaust system, a deep resonating tone emitting from the car.

They are worth it though, you can rev-match much easier for downshifts, and upshifting is overall smooth even at high rpms.

I did the ES motor mounts and the entire ES bushing kit all at once, except for the shifter bushing which I had done prior to the rest of them. I cannot recommend them enough. Especially on my car, which was a 91 SE-R with 90k miles on it... it made such a massive, gargantuan difference in the way the car drove and handled. It made the car feel 100% brand new again. Completely removed all the engine movement slop, suspension slop and made the car feel tight as hell. Literally, not "tYtE y0".

Yes the mounts do transmit some vibration into the cabin. But it's easily livable in my opinion, and not even worth considering as a negative factor. The rest of the bushings just plain kick ass. Do them all at once and you'll be amazed at how much of a difference it makes. Combine all that with a good suspension and you'll want to take the long and twisty way to work every time. :)

Do the front and rear mounts. In all the sr20 cars the left and right are fluid filled, if you replace them w/ the stiff es mounts your car will rattle itself to death. Just remember to up your idle to about 1000rpm to settle vibrations when your not moving. Also you will put a few more ponys to the ground w/ the ES mounts. Well worth the effort.

I just did the ES mounts last week in my black car, and am now taking every opportunity I get to recommend them. They made a HUGE difference in the drivability and feel of this 165k car. Sure, you get a bit more vibration at idle, but it feels better than it did before once underway - no bucking on shifts or getting on/off the gas. I also highly recommend Suspension Restoration Parts (suspension.com) as a vendor, nice people, great prices, and very timely shipping.

I wouldn't up the idle that much. Maybe a 100 rpm. I think that is what he meant?? The front and rear ES motor mount inserts are a really good investment IMHO. Yes more vibration and louder at freeway speeds, but worth it. Easy to get used to.

I was also think of getting the ES MM front and rear mounts. I have a question about the installation process. I know that the front dogbone mount is easy to replace, but the rear mount looks much harder to get to. Is the rear mount difficult to replace? Any info would be appreciated. TIA

One of the better threads I have started. You guys have some good things to say which I value.

I too did have the front and rear inserts in my B14 and it was a noticeable difference. I was fortunate enough to do the front control arm bushings as well and boy did that help straightablity when driving.

My concern is doing the side mounts and having that rough hard idle and irratating vibration. I have yet to drive a car with it to experience the feel. I am ready to just get the stock sides and then continue with the front and rear inserts.

My car has 170K on it and I don't want it to feel like it when driving so thats why I want to replace what I can in one shot instead of dicking around.

I plan on doing the front and rear control arm bushings on my current B13 as well as the shifter bushing and add in GC/AGX combo. This should hep ride quality a lot. Any more feed back is by all means welcomed.

Thanks guys :)

No, he meant "up to 1000 RPM". Not "up 1000 RPM". In other words, stock idle is set at 850 RPM, push it up about 150 so that it idles at 1000 RPM.

My concern is doing the side mounts and having that rough hard idle and irratating vibration.

For what it's worth, it didn't affect my idle at all. Rock solid. Just installing the side mounts shouldn't do anything to your idle. As far as irritating vibration, this is something that's 110% subjective. What's irritating to one person won't be irritating to somebody else. All I can tell you is that I have had both the full ES mount set AND the full JWT solid mount set in my SE-R, and both sets were easily within my tolerable limits. Some vibration transmits into the cabin, and you can feel it a little bit in the pedals and the steering wheel but it's not bad at all in my opinion.

It will initially be noticable at first because you're not used to it. You will get used to it in a couple days and then you'll never really notice it after that. The mounts don't make your car vibrate so much that it knocks your fillings loose - it's more like it just adds a little bit more vibration than it already had. As I said, it's easily within the limits of what I consider tolerable, for a daily driven street car, and the benefits of poly mounts are well worth it IMO.

I bought the ES torque mounts, and I know what they're like, but I also bought the ES shifter bushing.

What's it like? What does it do? It was cheap, so I had them throw it in too, what the heck...

I have a short shifter, if that makes a difference.

Where are you guys getting the ES stuff from? I highly recommend Suspension Restoration. They're really friendly, I only had to tell them everything once, and they got it right, and they were fast, and the prices are good. (better than Courtesy for the same stuff, actually)

I don't have the link here at home, but I can post it once I'm at work, if anyone's interested.

The ES shifter bushing kicks ass. I have the SMC short shifter and the ES shifter bushing... the poly bushing makes the shifter feel much more like it's a gated shifter. Very strong and responsive action while shifting, it's a large and noticable difference in feel. 100% for the better in my opinion.

Sounds cool, thanks Zak!

Add that to the list of stuff sitting around to add to the car...

This is what happens when you live in an area with cold weather/snow. Mods accumulate in your garage over time, and then they all get put on the car at once :)
