What're These?
 

These are on my 93 RX7 FD and I am just wondering what they are.

This bar is in my engine bay and was welded on, one of the previous owners had 1jz in it so it probably had something to do with that, do I need this or can i cut it out?

Whatever this is, it is on the underside of my car and it is bent, is it crucial? Do I need to replace it?
Thanks Guys

Without Pics your guess is as good as mine.

One...


Two...

First pic looks like a fabbed motor mount for the engine that was installed.
Second pic looks like someone decide to jack up the car at the wrong location and bent the subframe.
It's been done before and usually doesn't damage the car to the extent of the car not being safe.It just looks like shit.
