Default Big Loud Vibration when accelerating

As some of you may know, I got in a accident and pushed a 745li into a lx450 and that into a 4runner. I was able to rip out the front bumper beam and shove the radiator back in. Now when I drive there is a VERY big and VERY loud vibration that progressivly gets worse after 3k rpms and feels like the car is going to explode around 5k (i havent taken it to 6k, and am not going to).
Anyways, I checked out all the spark plugs to make sure they were ok, and they were. I also let the car idle with the coolant cap off because i heard that it would help with any air pockets that might be in the coolant system?

I don't really know what the problem could be, but the accident didn't penetrate the engine at all. It pressed the radiator into the engine fans "spinning space", but never got pushed into the engine. I don't know what the problem is, can anybody help?

Thanks,

-Jason

Is there a quick fix to this? How would I go about fixing it or replacing the harmonic balancer? Where is it? Also where are the flex discs and what do they look like? I'm trying to get the car running as best I can without spending much money. Thanks for your help and anybody else who could help me would be greatly appreciated!
