What mods would I need an engineering cert for? I know the engine, but what about manual conversion, lowering, body kit, headers, exhaust, etc, etc?

What sort of car? If you are using factory parts to convert to manual you won't need to involve engineers. Same deal if you are just using off the shelf (Selby, Lovells etc) springs to lower it. If you were going lo-rider with airbags or hydraulics etc then you would need engineer reports. Body kits are generally just bolt on (or fibreglass/bog on!) and generally have no affect on performance so again no need for engineer. Exhaust shouldn't be a concern either as long as you haven't hacked holes in the inner guards to run your headers through (like some V8 conversions into early Holdens). Of course there are db levels that you need to adhere to for rego and the exhaust needs to exit a certain distance past an opening window (no side pipes on four door sedans), your local exhaust shop should know exactley what is and isn't allowed. The later model the car is the less freedom you have with mods.

If you are talking about doing a V8 XF (as your sig suggests) then you probably will need engineer reports on the conversion. There was a thread recently in the Garage section about XF V8 conversions - do a search for more info.

Yeah it's not about the V8, already know that'll need a cert for it.

I'm still fairly undecided on my a car but I'm leaning towards an ED Fairmont of late, the old man said I'd need a cert for a manual conversion and lowering (which I plan on whatever car I get) but I didn't believe him, there's no way all these people would have lowered cars with the added cost of a engineers cert.

I guess being out of the TOG for 15 years has ruined his mind lol.
