Default Solid mounting engine

Can I ask people's opinions on solid mounting the engine if they have or haven't done it before?

The mounts I've got are shot to pieces, the car is used only for track days so not worried about comfort but thinking of welding some plates to the casing of the mounts to the frame .

I know if i do I will have to keep a eye for any fractures etc and things rattling loose..

What your guys thoughts?

Even for track days it will be unbearable, also it won't do the engine much good - all those stresses through the engine block etc and no absorption of any of the vibration.

As a short term fix can you "fill" the existing mounts with tiger seal etc to repair and stiffen then up a bit ?

I would not solid mount the engine.

Even race cars don't do that for good reason. I realise the vibrations will be bad through the car for the driver, but that is just the start of it. Those vibrations will eventually snap the mounts. You need to fine a good strong way to mount it but using some form of rubber mount or poly bushes. This is more important on a track car than a road car due to the abuse it's likely to get.

A buddy of mine got hold of some liquid polyurethane and made his own mounts. Again this might be harsh but a good compromise is to use the liquid poly to fill the cavities on the old rubber mounts and make them like new.

The mounts I've got are from a rover 400 I was struggling for a replacement which is why I thought of it . But I've just come across a picture of a Honda d series mount it looks the same just mounted other way round . Has anybody used them ?
Thanks

I might have some rover 400 mountd in good condition floating about. I used a rover 41r donor car when i built my clubby, but used metro engone mounts because i used a metro frame.

If you send me a pic of your cutrent mounts ill see if i can dig them out. My recollection tells me they were good

Thought I recognised this topic, it's been raised before here.

Richard says he wouldn't do it again, I'd trust his judgement!

stuff metal in all the gaps in the mounts and pump it full of sikaflex and give it a week or so to dry you will be surprised at the difference it makes.

I recon it's worth a go!
I we expect smoothness, why choose a mini?
I don't mind the ciment mixer feel lol didn't have any choice I think, had minis with standard mounts and s,c box/Weber etc it is what it is,
The mounts snapping are like falling domino,s
One leads to the other, and so on!
Dose a engine vibrate enough to bust mountings?
I don't think so
It's the rocking that bust stuff,
When we put lumps in a bench run Dino crate the were solid and Wer smoothness it's self!!
Think the question is? Can you make them?
Meaning ,yes but they have to be SOLID,

I'm not disagreeing with other points made!!
And if you want smooth that's cool,
Rubber mounts letting me down has been a major big fat head ache, if I could start again I would definitely not use factory fit smooth ride mounts,
