what about filling the piping with chassis foam? then you'd be the ultimate gangster

mjjstang · 05-07-2005, 05:19 AM

I did this about 8 months back and went to put the sr in, It took me 8 hours, (no joke) to get the engine to sit in the mounts, after 7:59 of struggling I took out the urethane with a screwdriver using my rage, and then the motor slid in like butter. maybe ill redo it one day with the stuff meph was talkin about.

I know I am digging this thread out of the grave, but I do not care.

I have a question that is relevant to the topic and has not been discussed in this thread or any other thread, that I know of.

Anyway....when the mounts are refilled and the engine is finally put back on the mounts, is the engine lifted back up to stock height?

Ritz S14 · 08-08-2006, 11:24 PM

The motor would only be slightly lifted if you "impregnate" the mounts in an "unloaded" position.

Basically.. the mounts are 15 years old, they'll sit exactly how you pulled them out.

Rayne · 08-09-2006, 10:43 PM

Thank you for the answer. I thought there might be a slight lift. I am going to fill my shot motor mounts this weekend.

I will post any helpful information I discover later.

haha... on my first S13 a few years back my tranny mount died on me. Horrible shaking at idle. I was getting Nismo mounts soon so I just bought the stuff at Home Depot and squirted the goo into the mount... while still on the car. Drove it the next day and felt so much better.
Hey, it was ghetto but it worked well for about 1 month.
I got a set of S14 KA mounts laying around... hmmmm....

So what happend after 1 month? I always thought about this, but I figured it'd benefit me to get the engine back to stock height.

*ManoNegra* · 08-10-2006, 01:13 PM

I got my set of Nismo mounts and tossed the old ones then. The Home Depot special worked fine but if I were to do it again I would follow the instructions above: take KA mounts off, fill with goo, wait a few days and then reinstall. Cheap and effective.

Luckily I bought some used ones that are oem with only about 60k miles on them (or so the seller claimed). So the swapping should be easy. I bought the urethane like 2 months ago, but I've been hesitant to try it because Im trying to sell the car...wouldn't want to mess anything up which would prevent me from selling it.

I bought the huge urethane bottle, so the gun is expensive, lol.

*ManoNegra* · 08-10-2006, 01:51 PM

the caulken (sp?) gun was ~10 iirc. If you're selling the car then perhaps you shouldn't bother. Mounts won't make a buyer want to give more $$$.

420sx · 08-10-2006, 01:54 PM

i did alot of pb mounts in last 2 years and they all hold up real well. +1 for industrial strength polyurethane! 3 99 in home depo u need 2 of them and a gun. thats it.

***S14DB*** · 08-10-2006, 01:57 PM

Another thing is to drill dead center into the side of the mount and drain out the silicone gel. Then fill the void with Window Weld.

420sx · 08-10-2006, 02:09 PM

but thats more work.

How does a motor mount work than? I thought it was solid. Is it like a hydraulic cushion? If the silicone fluid leaks out, will the mount compress and cause the engine to drop? Haaa ha, breast implants...

***S14DB*** · 08-11-2006, 11:52 AM

Stock KA mounts leak like fake tities. Nismo's are solid with no silicone fluid.

HyperTek · 08-11-2006, 02:11 PM

i got solid aluminum motor mounts and went this way with the tranny mount =rock solid

tubedae86 · 08-11-2006, 04:15 PM

lol, think mine are going to be solid in my rolla? Cant wait to get teh cross member powder coated!

krustindumm · 08-12-2006, 12:25 AM

I made solid mounts for my KA. I just welded plates across the factory mounts. The engine doesnt move

Rayne · 09-11-2006, 11:10 PM

Here is some useful information I found discovered.

1. Do not buy the "Liquid Nails" Polyurethane Construction Adhesive, particularly if you fill your mounts as described in the original post.

I think I could have done a better job on the motor mount I was able to get off so I am going to buy some used mounts and do a write up on what I do differently. I will post the pictures and information in this thread after everything is said and done.

TipStylez · 09-11-2006, 11:39 PM

^keep my updated. Il be doing this soon, and been looking for the best way to do this and what to use.
