I4 engines have an inherent dynamic imbalance that makes the engine vibrate up-down at two times the frequency of the crankshaft. This is usually countered with soft engine mounts that eat this vibration. Land Rover mounts are very stiff and don't absorb much of that vibration, making the whole car noticeably vibrate on idle. This adds to the sporty feel of loud exhaust, no windshield, GRP seats.

I'm not sure there Albert, I and a few builders around me have replaced the sierra mounts for land rover fitting them to various engines. On tickover they provide enough dampening to reduce vibration with the larger and softer sierra mounts you can noticeably feel the engine move when driving and you get a lot of movement back through the gearbox and stick, feels like the engine is sat on 2 large bowls of jelly. I've seen 2 sierra mounts snap at the bottom bolt because of the extra movement and lateral forces induced by hard driving and cornering. One on mine i didn't notice till the engine was removed on the cvh.....

My car has a resonant frequency at 4k you can feel when dropping down the gears but that's more the car then the engine. Again it's all about choice, good thing about the self build. In fact suns coming out here so might be going out soon to test them again..........
