I'm not mechanically-minded at all but this thread will document both the personal attempts I make at installing or modifying aspects of the vehicle as well as any other mods that I can't or won't do.

Triton in Renmark, SA soon after purchase.
First mod I attempted was a snorkel. Purchased one off eBay, branded CaneToad. Quality was fine and all the pieces were there. I don't think they are any different to any of the other cheaper eBay snorkels. I was content with purchasing a cheaper snorkel, obviously with lower expectations.
I based my install off the 'Service My Ride' YouTube video and the Ironman snorkel installation instructions which are identical.
The only comment I have to make about the installation is that I will (at this point in time) never be doing another snorkel again. When I said i was not mechanically apt, I meant it. I started at ~1:30pm and finished up after midnight with a 20 minute dinner break.
The main issue I had with this was trying to get the snorkel to conform to the body of the car correctly (see picture). Not sure why it didn't work but I had to file a lot of holes and fiddle about before I was satisfied. The front end of the snorkel didn't sit flush and when it did, the back end didn't sit flush. It ended up pulling in a fair bit after tightening the bolts but even then I didn't do it up completely for fear of snapping the plastic.

This ended up being a lot less obvious once the bolt was tightened behind it.
Here are some more pictures of the incredibly arduous process.






My biggest concern is that the rust proof paint I put around the holes wasn't enough. Really not wanting to undo everything and repaint but I might have to. Any suggestions would be appreciated.
Like I said, never again.
The engine starts, but haven't driven it yet.
Big thanks to the forum member who lent me the hole saws. Cut through the metal like butter.
