Make Your Own Motor Mounts - Here's How

Post by **mrzabala** » Sun Dec 17, 2006 7:53 pm

hey Greg, was wondering if you can give us an update on how this motor mounts holding up and such. If possible can you take pictures to get a better idea? Thanks. JDM and I plan on doing this motor mounts but would like a good idea on what to expect. Thanks.

300 miles since installation, and these are awesome.

I have had to tighten them a couple times, as it seems the little "ridges" on the mounting surface compress a little as it heat cycles.

Notice how the top and bottom of the mount were concave, due to the meniscus of the Flexane when wet (top) and the shape of the cup (bottom).

Nonetheless, I'm super-happy with how they're working out.

Lol THANKS QV. I thought that was a couple weeks ago but it was only 2 days ago.. Sigh. And one thing on frsport. Someone thats avaliable on aim for frsport.com keeps leaving me off when we start a conversation. I made an order but I wanted to add to it before it was shipped. Any suggestions?

so how about subframe bushing replacements? think it would turn out ok for somthing like that?

Post by **AZhitman** » Thu Dec 28, 2006 11:51 am

I think it'd work great for whatever you wanted to make...

I'm going to try it out with a set of tension rods.

Post by **greengt2nv** » Thu Dec 28, 2006 1:31 pm

F_ING SWEET!!! My motor mounts are ****. and let us know about them tension rod bushings. Oh and just a suggestion. but I think there should have a DIY section on the forum so its not hard to find sweet *** **** like this! just a thought.

have you made exaust hangers yet?

maybe next time try sanding the washers with very course sand paper to make it very rough,give the flexane something more to cling to.>>>>A.J.

Tension rods--- yes!!! My Z's tension rods are putting in overtime. Please let us know how that goes as well!

Hey just a quick thought when i was reading through here.. To avoid a concave shape, you could always use a soup can... just a thought

No, it would still be concave. That is due to the properties of the fluid, and material of the container, not the shape itself, as well as the surface tension of the liquid. If the liquid is attracted to the container, then it will try and stick to it as much as its surface tension would allow. That being said, maybe flexane and aluminum would not have that same attraction, so you may be right.

i found a great place to get mounts from jgstools.com come i got my semi solid mounts from them for about 150-180 i cant remeber which but their just fine if you can deal with vibrations

Post by **AZhitman** » Wed Feb 14, 2007 9:19 am

Yeah, the meniscus of the fluid creates a slight concave shape. Realistically, once they're bolted in, it's pretty irrelevant, but I trimmed and smoothed the edges of mine anyway.

im tryin out this idea of urs..were did u order the flexane 94...and how much?...dont no were to find them..

Post by **AZhitman** » Wed Feb 14, 2007 7:05 pm

It was like $50, not sure where I got it from. Google it?

This is what I found... http://www.markingpendepot.com...D=193

I've already urethaned my stock motor mounts, so I'll try that first. This is next on the list if I don't like it.

These would not be a good idea for tension rods, for the same reason that stiffer busings (whiteline, energy suspension) are not a good idea for the tension rods.

Your best bet for awesome, reliable tension rods are high misalignment spherical bearings or heim joints/rod ends.

I already ordered 2lbs for 2 sets of motor mounts. Hopefully it will work so I work on my wiring. Question for you Greg is can you inform us on how the motor mounts are right now or sometime soon? And happen to have any ideas for improvement (before I start making mine)? Thanks

Post by **AZhitman** » Fri Feb 23, 2007 7:59 pm

I wouldn't change a thing. I snugged mine up after 24 hours and they've been perfect since.

I'm convinced this is the BEST way to go for motor mounts.

Post by **mrzabala** » Fri Feb 23, 2007 9:06 pm

Thanks for the input. Ill be getting mine on monday so Hopefully I can have it in 2 cars soon and have a test drive.

Post by **BlueTyGator** » Wed Jul 18, 2007 3:49 pm

Anyone given any thought to using this stuff on the tranny mount?

I need to replace all three mounts and was thinking about how I could fab up one for underneath.

Advice/suggestions?

Post by **AZhitman** » Wed Jul 18, 2007 4:12 pm

Should be simple. Look at the factory mount and decide what needs to be done.

back from the grave...hmmmm someone is taking after me

Post by **ZiG** » Sun Sep 30, 2007 4:20 pm

So, uh, any word on tension rods? I'm curious how they could be done so that they would stay in place.. Or would you just 'cast' them right in place?

OK, at idle, it's a little rougher than the Nismo mounts were. Good thing we went overboard having this rotating assembly balanced.

Once I accelerate, it smooths right out, and feels smooth as ever. Believe it or not, the car actually feels more "solid" or "well-planted".

I'll be inspecting them after every drive for a while to ensure they're holding up well, but I did several full-throttle runs and it felt great.

I just stumbled on this thread. Simply amazing. I will offer a suggestion though. You mentioned that you had to tighten a few times because the urethane compressed in places. Why not put a large washer on the top and bottom when you are forming these. Basically Put a washer in the bottom of the cup, put the bolt through it, pour in goo, put a washer on top of goo. This should also keep the bolt centered in the cup.

U my friend are one Smrt I mean SMART person Amazing

Post by **ZiG** » Sun Sep 30, 2007 6:41 pm

lol, yeah, put a washer top and bottom, wtf would you even need the flexane for!

I saw this when you first posted it up and I still think it's a great idea. I do have a question, though. Do you think it might be a little more civilized if you used Flexane 80 instead?

Post by **mrzabala** » Sun Sep 30, 2007 8:17 pm

Made this motor mounts awhile back, pretty much the same way Greg made it. Ran for about 500-600 miles. Its rough at idle. I had to raise idle to 1500 to keep it somewhat smooth. Literally feels like your in the vibrator bed in a chiropractors office. Everything blurs out on the rear view mirrors and side mirrors, if your transmission mount rubber spacer is cut off, it makes even more noise. On the positive, the turns are awesome. Grips so much better. Recommend this for the drifters, but not for commutes.
