2003 supercharged g35 guidance
 

So I've recently acquired a 2003 supercharged g35
and have no idea how to maintain/ care for it.

What goes in this (inter cooler) reservoir, any liquids? It was completely empty when i checked
i looked online and read the manual and it seemed like a coolant reservoir so i filled it with coolant. But now im not so sure if thats what its for because i lifted the car and looked under. This is what i saw

The light blue is the (inter cooler reservoir) which has a hose connected to what i think is a pump (green)

The heat exhanger at the bottom (inter cooler/little radiator looking thing with a stillen logo) do any liquids go into that? I'm completely lost
Ive been reading guides and manuals but found nothing

And am i supposed to change the supercharger oil as well? If so how do i go on about doing so.
Thanks for your time.

Dude WTF??? Did you seriously put something in your car that you have no idea if it even belonged there? And you bought a supercharged G which you know nothing about, wow. :eek:

I really want this thread to be a joke because I am baffled at what I just read but I digress and will make a couple of sane comments for the moment. Before you do ANYTHING else you need to get that car to a shop that has SC experience to give it a complete inspection top to bottom and back to front. I wouldn't even start it ATM, you might have put coolant in the right place but if you didn't that move could be catastrophic and cause massive problems for you. Looking more carefully at your light blue line it seems to go into the valve cover unless I'm seeing it wrong but if it does uh oh. Read as much as you can on the forced induction thread and bettter yet, the same thread on my350Z.com. Very knowledgeable members on both sites but the Z guys do it a lot more to their cars so there's more chatter over there. I'll just shut up now and move on but GL, hope everything turns out OK for you......... :dunno:

EDIT: Nvm though it was an air-to-air system. Check out the installation instructions it lines out the details of the water-to-air exhanger.

Ohhh also, you ABSOLUTELY MUST use 91 octane fuel! Also, when changing your spark plugs you need to use NGK PLFR6A-11 and you need to reset the gap to 0.043, if you don't know how to gap irridium plugs then you better leave that to the professionals, feeler gauge and a pair of very small pliars is what I usually use.
