Split motor mounts on an EJ22>Loyale swap

On my RX (EJ20G swap) the car had the round liquid filled mounts when I originally got it. Within a short amount of time those mounts were completely tore up. Since its my go fast car, I decided to spring for some Group N STi engine mounts. I believe it was $60ea from www.subarugenuineparts.com These mounts are pretty gnarly, and I doubt they'll give out anytime soon.
On my '86 Wagon that just got running with an EJ22 I've also notice the mounts starting to split. These mounts are the square rubber ones. I haven't decided on how to replace them yet. Compounded the problem on this car though is a lack of a dogbone (upper engine stabilizer) and decent tranny mounts. But, replacing EA82 tranny mounts is like a waste of time, they practically disintegrate putting them in.
So, there is 2 more for the records. I'm interested to see how many others come forward with this problem.
Whats horrible about it is that when the engine first goes in its no problem... but then as you run it just tears them up. I found out both of mine because the exhausts started hitting on crossmembers and such.

I've not noticed any problem with my swap yet.....but I haven't looked. now I'm afraid to crawl under there
especially since the donor car had 230k miles on it BEFORE I swapped it and started abusing it.

SO that's one EJ22 swap that hasn't had problems.

What method did you use to get the plate that way? Just grind it down? Or did you have something more precise?

I got some used mounts from a junk yard that were in good shape. I made some wedge shaped washers from 3x3x3/8" plate. They are tapered from the 3/8" on one edge to zero on the opposite edge. I drilled a hole in the center and had to grind the rear corners so they would fit flat in the recess in the cross member. I also had to take a hammer to the cross member and completely flatten the step on the upper or outer side of the recess to allow clearance for the mount. It fits good.
Those tapered shims look like a great idea. I am finishing up my EJ22 Loyale, and I have driven it about 5 miles and one of the mounts already sheared in half. I will get some new mounts and make some shims using your dimensions. Thanks.

There IS a reason for it. Without one, you WILL tear your motor mounts, it's just a matter of time.

Also, I rigged up a mount to use the pitch stopper from the donor legacy, along with the tabs on the SJR adapter.
The Group N mounts defintely transmit more vibration to the chassis at idle...but they feel great while driving and shifting.
The EJ22 is now firmly anchored and ready to be abused.
What is the solution for the soft EA82 tranny mounts?

Bringin this one back from the dead!
Has anyone come up with anything for the trans mounts?
I'm considering ditching the round mounts on my donor engine and coughing up the cash for the group n's. But what's the point if my trans mounts are crap?

If you have a good set of transmission mounts you can fill them full of window weld urethane and that will help immensely. just go slow and fill it up in layers,and let each layer cure before adding more.The mounts have to be very clean so scrub them soap and water and an old toothbrush.

Sounds like a great idea, thanks Uberoo.
Just to clarify, are you talking about filling in the open space? And maybe adding a layer to the outside of the existing rubber?

Yep you want the entire thing to be one solid block of urethane.Just do a layer at a time until the whole thing is solid.Might add a bit of NVH though..
you can also chain the engine down a bit which will limit how much the engine can move on the mounts.Lets say hypotehically the engine can move 1/2" on the mounts,but if you chain the engine down it might only move 1/8-1/4".Just run a chain from the engine to somewhere solid...
