Are you leaving them polished Al, or will you be anodizing them colors as well?

ill anodize almost all of them black and keep maybe 30-40 of them in raw aluminum. Could do colors but once we get the groupbuy rolling ill have everyone do a poll on which colors. it costs me $ per color per batch so its not cost effective to run a single of 1 color.

Understood. I would be interested to see a Red one myself... To go with my engine bay's aesthetics...

I'm noticing though, the pics look like the tank from 09-11 Nismo's and 2012+ bases.

What about the 09-11 base models? We have a different tank. It has just a plain black plastic cap.

Red black silver and blue are probably the top choices

.... Black cherry.... :tup:

I presume the coolant in the radiator heats up and expansion moves it under pressure into the pressurized tank where it cools and then returns to the system. Here's a pic of the cap off the radiator.

And a close-up of the cap showing it's just a sealing cap with no relief spring.

The third pic shows the cap that is on the coolant tank which is a normal radiator cap. I think the idea of the system must be to increase the circulating capacity of the cooling system by 2-3 quarts. It's obviously not just an overflow system. I think this is the same type system on GT-R and the technology may have trickled down from that system.

Looks like to me someone swapped the two caps in their original positions.

I can verify that my 2012 Sport has the same setup - pressurized rad cap on the plastic overflow tank, and not on the metal spout.

the pressurized tank does absolutely nothing for performance and you will not see any gains by having 1 style over the other.

I will make an adapter in the near future so that if you wanted to use either or then you can.

looking great!

I miiiiiiight have to get a quote or two from you on some round stuff soon. Making rounds in the verticals kinda sucks. But I dont have enough round part volume to justify a machine.

i hear ya on that! this lathe is VERY FAST...shoot me a pm. I would love to take on some of your extra work.
