Outer Limits 4x4 Board

Hi,
This is all new to me.I used to own commodores up until 1 week ago when i got my first 4x4.
Can i fit EFI onto my 4.2 petrol motor?
Approx how much would i be looking at, whats needed ,and whats involved?

Up until 1 week ago,i didn't know what i was missing.


Any help much appreciated.
Thanks James
