Can any one help me?
I was looking for the name of the metal alloy that makes up the cylinders . I know it begins with a (N) but i can' t remember.

Also does anyone have any thoughts on rebiulding a 2.4t
on there own?

I have not been able to sell mine , so I was thinking of rebiulding it to bigger specs, what are my options?

Any help would be great.
