Engine Mounts ???? Help Needed (pls no flame)

[miggs32]

I am pulling my KA (yes "T "is what the future for this motor) but I want nice engine mounts. Not the crap they sell you at the store. Little help needed?

[EazyBreazy]

get some solid ones from one of our sponsors ie. spl parts or phase two motortrend

[Structure240sx]

you can fill your stock ones with 3m window glue from home depot/lowes

get nismo poly mounts

or some other solid type mounts from a few different companies (some metal some solid poly)

[Ezzo]

What do you mean by "Nice mounts" are you going for a more connected feel to your engine? then you would want a more solid mount. if you want it to be comfortable then the OEM Nissan ones will do just fine for your ka-t. I hear the Nismo's are still comfortable and add a much more connected feel. I plan for them in the future but I haven’t been in a 240 with them yet. As for the Window Sealant that structure talked about that’s also another alternative I know a lot of people take.

What you want to look at when filling your mounts is Shore hardness. Shore hardness is A measure of the resistance of material to indentation by a spring-loaded indenter. The higher the number, the greater the resistance. Normally used for rubber materials. ( gotta love Google ) So prettymuch measuring the resistance of rubbers before the surface punctures

The higher the shore hardness the stronger the urethane is going to be IE. more vibration is going to go thru to the driver but your going to have a stronger hold against engine flexing. So you sacrifice a little comfort for a little stronger of a mount.

Different Sealants I’ve seen used in the past are as follows.

1. PL makes a Poly Urethane Construction Sealant that has a shore hardness of 90. Runs about $5.99 a tube



2. 3m window weld (08609) Fully cured it has a Shore hardness of 55-60 that runs between $10-$15 a tube.



3. http://www.mcmaster.com/ Sells a flexible urethane used for casting compounds. It has a shore hardness of 80. Comes in about a quart I think. Runs about $24 and you don’t need a caulking gun to use it.

Thanks to Chris D, he e-mailed all of the companies to find out the shore hardness of those products. So far a lot of people are Very happy with the PL products they have a whole line of urethane sealants. I'm sure that other people have used more than these 3.

Besides filling your mounts you can ither go for the OEM replacements, Nismo makes a kit, And ive seen some solid metal motor mounts floating around here and there.

When filling the mounts you should layer the urethane product that your filling them with so that the curing is faster and you will have less air bubbles. with the MC masters stuff it is in a can and quite viscous so you can probly agitate a lot of the bubbles out of it before you pour.

Hope that helps you in your decision!

ill be filling my stock mounts with 3m window weld either today or tomorrow. thanks for posting that info up ezzo. makes me feel better about going with the 3m ($14 at the zone). not too stiff, but just about right. i wonder if theres a way to compare these to the nismo mounts or pury poly mounts with the shore hardness measuring.

[Ezzo]

Well you could allways try to E-mail Nissan or Nismo about the shore hardness of the mounts. Being a part between 89-94 they might think it an odd question lol. If anyone has access to a Durometer (sp?) they could easily test the stock mount. I remember the stock mounts on the MR2 were around a shore of 70. So as a benchmark for you thats a 2.2l NA motor. Are you going to add the 3M in addition to the motor mounts insert? or are you planning to eliminate the insert and make a whole new piece out of the 3M? tell us all how it goes and your oppinions on it.

[j-z]

im just straight going to fill in the stock ones with the 3m. basically itll all be one solid mount when im done.

[fiznat]

Very nice post Ezzo .

There are a lot of options for motor mounts (read above), but I personally think money can be much better spent elsewhere. As long as your OEM mounts are in good shape I seriously doubt you need anything more than that.

[j-z]

my stockers have 145k miles on them and i can move them by hand without anything attatched to them. $14 isnt a bad tune up for worn mounts, especially when ill be more than doubling my torque output.

[1995240sxSE]

I used 5 hockey pucks for mine they are VERY stiff and you get lots of motor feel and at $1.00 per they are the cheapest motor mounts on earth plus they clocked my motor for clearence for a turbo!!!

[Ezzo]

HAHA i heard about the hockey pucks!! please take a pic of them if you can. I thought it was a joke when i first heard it but then when i started to think about it, it sounded really feasable.

And for the 20-30$ just to add a little extra stregnth to some tired motor mounts its not a bad saturday project.

[miggs32]

Never thought of filling them. Thanks all for the info.

[j-z]

i filled my mounts today and they came out really nice. too bad i cant test them yet though. still have to assemble the motor.

[scarboroughdub]

so how do you go about filling the mounts.

step by step would help.

[j-z]

go to autozone and buy a tube of 3m window weld for $14.take off your stock mounts.clean your stock mounts with degreaser.fill stock mounts with the 3m.let it sit for 24 hours and reinstall.

[1995240sxSE]

take a look at my 911 emergency post and look for the pic of my motor you can see hockey pucks!

[shotgunhunter4]

Wow, I had no idea you could do this. Thanks this is awsome!!!1 I love cool cheap mods like this.....and i was going to spend 180 dollars on Nismos..Pshh..

[Iamjohnhayes]

or if you want to buy solid poly mounts jgs makes a nice set 120 for the pair

[shotgunhunter4]

Yea, 5 dollars still sounds way better than 120. I picked up my tube today at Home Depot. I plan on filling the mounts tomorrow, ill let ya'll know how it goes down and how the ride is.

[Craving4Boost]

where are you suppose to fill it in from? are you suppose to cut a little hole and squeeze it in or something?

[Chezedik]

Will clocking the engine differently hurt the trans mount?

[Iamjohnhayes]

how much clocking are you talking bout? and im sure if you have a good solid-poly mount it cant hurt it too bad.

[j-z]

daaaaaaaaaaaaaaaaang..... my mounts are fully cured now and holy shlt! them things are SOLID and arent going anywhere. one tube was just perfect as i used the whole thing up on all three. and when were talking about filling the mounts, you just squeeze that shlt in all the empty spots of the mounts to make it one solid mount. $14 for all 3 vs $120 for two vs $230 for all three hmmmm..... yeah thats a no brainer!

[Chezedik]

With the 3 puck, two puck method.

Nice man, I can't wait to do mine. don't think ill get around to it today. How long did it end up taking you? and whats up with the $14?? is that what you paid per tube? i got mine for 5 bucks at home depot. Congrats on a cool cheap mod well done though

[j-z]

yeah the 3m is $14 a tube. it took me a total of 15 mins to do all three. reason it even took that long is because one of my motor mounts i couldnt get out of the car. the nut stripped while i was trying to impact it off, and i couldnt even get it off with those grabbing sockets cause its in such an awkward position. so i was laying all up in the trans tunnel trying to squirt that shlt in there resting on the subframe. but i got it done and it was well worth the $14 and 15 mins.

[shotgunhunter4]

alright cool man. I picked up the poly urathane tube. We'll have to see how it is compared to the 3m.

[Neil]

i want to try this for my subframe bushings... definitely going to find some something with a shore hardness of 90+. Thanks for the relativity, Ezzo

My Nismo transmission mount looks just a tad twisted I dont see any future problems with it down the road. The hockey pucks are good, just alot of vibs at idle, when driving no problems at all. Nice strong feel with power all going to the drivetrain.

+ 1 on the JGS Mounts, defentily worth the money, especially if your going the turbo route.
