Not emissions, but there are registration requirements that have to be met - assuming he is going to get it "engineered" (officially approved).
Some people try to keep it under the radar........
A roadworthy test in WA is not a difficult thing, but it just has to be right, and an engine swap in particular has certain things that must be met. For instance, it is a lot harder to get an older motor passed in a newer car - trying to put say an SBC where an LS was is heavily frowned upon, but putting an LS where an SBC was is liked. (This is partly to do with "cleaner running" newer engines)
Then if you upgrade performance they like to see better braking (He said he was doing brake stuff also, so that should be no problem.)
Talk nicely to the inspector and they give you good advice. Rarely does a car pass the first time, because there are all sorts of little things that they pick up on - worn wiper blades, tears in the seat (put on seat covers and they don't look under them!), any sorts of oil leaks etc.
We are fairly restricted as tow what we can do without an inspection, but mods can be passed with reasonable ease, and once p[assed you are all good.
We are only allowed to lift 2" total here (including tyre diameter, so if you get a 2" suspension lift you technically must run standard diameter tyres!). You can go higher, but it needs an inspection and engineers report. Most of time the police don't fuss unless it is extreme or you are being right doofus and mouthing off at them.
Hey Noot - I will be keeping my eyes on this thread, and on the lookout for you once you get it out there.
