What are some good supporting mods when doing an engine swap?

I have a 2000 honda civic that i plan on doing a b18 swap and i don't want to bend my frame so what are some good supporting mods for that?

Hi so actually your cars body is classed as scrap metal now why waste any money on the engine and transmission.Yes it is well passed the intended 8 years of life.

If you need to ask you should not be doing this.
