Would i need an engineers certificate to put a 3.9l and zf from a disco into a rangie - 1976 mod or a 1992 defender ute in nsw or can i just bolt it in and change it on the rego?

The rangie will be ok but the defender may need engineer cert.

In NSW you are allowed to self certify if the engine is less than 15% bigger than the original engine and there are no other changes ie engine mounts etc.
Read the RTA site on this . It is quite good.

Thats what i thought, but the defender came out with a 3.9 in other countrys - us and europe. Also if you put a new 4.6 block where a 3.9 (or 3.5) was, thats more than 15%, but the same/similar engine block. I remember an engineer telling me years ago that i didnt need an engineers for a 400 chev in a hk premier because they came out with small blocks anyway.

anyone had any real life experiences?
