Speak to Kamikaze Motors - I bought a Mongoose MAP80G (upgrade alarm, uses standard key fob) off ebay and they arranged the install. Can't remember how much it cost all up but it was good value. Works great.
I've read a few threads which say otherwise, but cbf digging them up. By most accounts, this is acknowledged as one of the best n/a mods for a 350z/v35.
Anyway we've got enough takers, so up to you.
The ISO kit comes with a valve that you open when the temperature is really cold (but subsequently reduces the benefit of the ISO spacer). It certainly won't kill you car. The main difference is the copper kit doesn't need this valve.
Unless you live in the snow I wouldn't worry about it.
The Motordyne has consistently better reviews, especially the ISO version.
That's as I understand it. You can choose whichever one you like. I think ISO is the pick for Australian conditions, unless you regularly drive to the snow.
I'll update you in the Sydney buy.
^^Noted. Damn annoying SAU.
Melbourne seems to be sorted if everyone confirms.
