Hey guys sorry if this has been covered before but tried searching and couldn't find anything. Im putting a 304 EFI 5ltr out of a VN in my VL i would like to know if in VIC this requires an engineers cert? I was lead to believe because the walkinshaw had an injected 5ltr i didnt but judt need confirmation thanks.

Na I don't think you do engineers wise. Just as long as the emissions gear is correct. I'm not sure but I think since your going with a newer motor in an older car it should be fine. Do you have to re rego? I wouldn't stress til anyone catches you out

Yeah thought it should be fine but just wanted confirmation. And nah its got reg so recon not even tell them?

if your vehicle is a six cylinder non turbo then I believe you will need an engineer's certificate. upgrades to both front brakes and suspension may also be required. I'm in the middle of completing this conversion on a NA 6 right now and both brakes and suspension needed an upgrade

Ive had 3 of them over the years, one was originally a 6 n/a, one factory turbo, and a factory v8, never once needed an engineers. Why bother anyway these days, go the ls conversion at least its worthit!!!

This comes up all the time. Mine was an n/a 6, but is registered as a v8, Not engineered. As above just fit the correct suspension and brakes.

If your in vic you will need engineers cert!!!!

^^ agree with gouldy, went to Vic roads a couple of years ago to get my engine number changed over after an injected 5 litre conversion and the prick behind the counter said I needed an engineers certificate, I tried to explain to him that I shouldn't need one considering the Walky came out with an inj 5 litre, but wouldn't back down so I left it at that .ended up going to werribee vicroads a few months later and copped the same thing. So ended up getting an engineers cert. pretty costly
