On Friday got new gearbox installed. Also put on a number of polyretan mounts and engine aluminium mounts. Next tried to put aluminium mounts for gearbox also... its not doable.Also gearbox broke because it has uber weak mounts on it. To make it work the gearbox should be reinforced first. And a friend of mine who makes 1000+ hp cars occasionally in his workshop told me he never uses aluminium mounts for gearboxes, that wont never work. Ok, welded the gearbox together again and installed it with stock mounts. When all was finished i tried to start the car... wtf the car wont idle at all, and works like with 3 cylinders, wtf, ok reset... same thing, damn. The problem was one vacuum hose had flewn off, jeeeze. Got that fixed and started the engine.... ummm.... its rather insane, the vibration is all over the car. I tried it on Saturday on a racetrack, yes i think there could be a little power gain there tho. But the vibration is nuts.
I assumed that vibration will be quite insane, but handeling should have improved quite a lot. No inertia forces caused by engine movement. Do you have any pic's of transmisson form where it got broke? Did it brake when you were driving? I think aluminum subframe and differential mounts are also needed to use aluminum transmission mounts. (I think too much flex from rear axle broke you transmission)

starting to look awsome, but still tons of stuff to do, all the little things are taking so much time and nerves.
