Poly engine mounts

[Pantera6]

Reviving an old thread…. I am likely to be in need of replacing my engine mounts in the near future and would be grateful hearing from the members who swapped all of their original factory mounts to polyurethane when this thread first started (Peter Thomson, Nick Mann, Davezj…others?)

Specifically, I am interested to know how your (Prothane) polyurethane mounts are holding up 3-5 years after installation and if you've had any issues with sagging of the polyurethane mounts, especially the rear roll-stop? Also, if you've changed your polyurethane mounts the second time around due to issues, if you could please elaborate on the issue and what you have replaced your polyurethane mounts with (new part numbers/links etc.) that would be most appreciated! Many thanks in advance!

I've used them for 3 years upto when the Legnum crashed. After that they lived another life with the new owner of the engine and they are still solid, no sagging. My experience is that they do offer more firmness, which slightly decreases the comfort from the original ones (some slight vibration is added at specific (low) rpms). If I were to do this again and the original mitsu left and right engine mounts were still good, I would leave them as is and only replace the front and rear roll stopper with poly urethanes. Those are the two that get the most to endure and wear out fastest.

[Davezj]

No issues for me, none at all, no sagging no extra vibration.

All good for me.

I have them for 3 years now - all 4 mounts replaced with the Prothane ones from Eclipse V6 (front roll stopper from a 1G Eclipse).

No sagging at all, engine sits as it should, would do this again and recommend this mod.

All good for me, have had mine in since 2009 and had no problems. I was running the stock front roll stopper until last year when I replaced it with the insert though.

I had mine fitted in 2008 and after removal in 2013 (scrapping vehicle) they been solid as new. Highly recommended. I had though uprated hardest compond of polyurethane inserts, so all vibrations whilst idle were felt. But also better engine/throttle response feeling.

I got mine off eBay.


Different engine mount related problem:

So I've got a bit of a mismatch here. Have I got the wrong kit?

The cross-member mount is too small for any of those inserts.

[peter thomson]

You have bought the kit for the eclipse which has a bigger front mount. It's the same kit I used but that's what was available at the time. I just bought the eclipse mount and used it

[Davezj]

You bought the V6 eclipse kit it loos like to me any way.
You can go out a buy a V6 standard eclipse front mount.
This why I got energy suspension parts to set up the deal001 which includes the correct front mount.

[mattnz]

Damit, thanks guys!

Is there a JDM car that shares the same mount? I don't like my chances of getting an Eclipse mount in NZ!

[Davezj]

This is what you are looking for, but it will take time for delivery.

i searched ebay with 'eclipse V6 front mount' this is what came up, i belive they are the correct ones, but they are in USA.

or you could just buy the correct polley insert, to may be cheaper in the long run.

[mattnz]

Was there also something about saving one of the sleeves from the original mounts?

[MarkSanne]

Nope

[Nick Mann]

The front roll stop. The supplied metal tube is not long enough.

[Davezj]

yeh keep the original metal centre sleeve from that mount and just get a hack saw and run the blade down the outside of the sleeve to clean a lot of the old rubber off it. but don't clean all of it off leave some on to make the sleeve a tighter fit into the new polly insert.
well that is what i have done in all the mount convertions i have done for mates.

[mattnz]

Cool thanks!

installed mines a long time now and up till the date i got zero problems.....DSC00012.JPGDSC00013.JPG

Here is a question for those more knowlegeable on the site. Would the eclipse v6 front mount not be the same /similar to a v6 magna or mitsubishi 380 sold in Australia (Galant elsewhere) ?

[Davezj]

why not buy the correct kit that fits all the VR4 mounts.

you can buy them individually or as the kit that i got energysuspensionparts.com to put together, the number and a link to the kit is specified in this thread.
