Engine stabiliser or torque arm thingy - needed or not?
On all the front engined rear drive cars I have ever had (and usually taken to bits at some stage), I don't remember having stabilising bars at
the front or the engine block to absorb torque.
But all the transverse engined cars all seem to have them.
Do I need to fit one when an engine designed for east/west mounting is fitted north south? The engine has new mounts fitted at approx centre of mass
either side of the block in conventional way.
In the photo archives I have seen some installations where these bars have been fitted, and some without.
It makes some sense that in a transverse installation the whole drivetrain will twist from the torque reaction or driving the wheels and this needs to
be restrained.
But then the engine/gearbox is delivering the same torque whether it is driving the wheels directly, or through a diff.

The mini used to have one fitted to the thermostat housing.
Im considering one for mine, but need it running first!!

No it isn't, unless your diff has a 1:1 ratio.

Very good point ...
I did think about that but came to the conclusion that the torque generated by the engine would be the same irrespective of what it was driving.
but ... I suppose the diff act as a torque multiplier when incorporated into the engine/gearbox assembly.
So is the answer no, the thingy is not needed?

The answer is yes as far as i am concerned
see post above
I thing it depends on your engine mounts rubbers mine are horizontal but if they were say 45% it would stop the engine / box rocking

My engine mounts are about 40 degrees to horizontal.
