Outer Limits 4x4 Board

Gday guys my names Nick. iv been reading this site for a while now and i was wondering if you can help me. I have a 95 rodeo 2.6ltr dual cab, i would like to put a commodore v6 in it. Is there any one who has done this and can give me some pointers on what parts are better or problems that may accure. Im thinking about doing it myself, how much will it be roughly. Will my it help my fuel economy aswell. thanks heaps

My advice would be to use the money and put it towards a later Rodeo V6. Alot less mucking around and easier to service etc. May end up being cheaper too
