Does anyone know if i need to modify my standard cross member to put in a L18 or can i get away with the standard one or will i have to get a new one made all together??

<<< a quick search over here will net you all your answers mate. I believe this topic was explained again a few weeks ago

You can either modify the crossmember (the traditional method)

or modify the engine brackets, and leave the crossmember alone.

Depending on the oil pan you use, the crossmember need no modification. Otherwise people mod either the pan or the xmember.
