Looks like some kind of ignition booster...

It's either that or a fancy voltage regulator. The Japanese are really into that line of electronic tuning. Sometimes it makes power, sometimes it doesn't.

basically the same thing. i was looking at a 300zx last weekend that had the HKS setup for his TT ignition. it is kinda like a capacitor/amplifier for the ignition circuit and he said it works really well. improves both spark and life span of the plugs, especially on turbo motors where detonation is more of an issue

Sounds like a little CDI box. Other Japanese tuning companies make ones that just sit on the +12 V battery circuit to smooth out voltage flow to all engine electronics. I bet those two boxes are one of each.

Luckily modern COP setups don't really need an additional boost unless you are running crazy amounts of boost. Evo X guys are seeing benefit coil upgrades and CDI amplifiers at around 30 psi of boost or so. But that's common for these little 4-banger turbo powerplants.

Call me crazy, but the first pic is way different than anything else i've seen and I kind of like it. That said, does anyone know what all those hoses are going into the overflow tank? Are they even functional?

that is a ARC coolant/oil catch can.... it is functional.... you never see them around because ARC discontinued that tank after they went bankrupt... they re- opened again but they only sell a tank that is compatable with other vq engines.... makes sense because that tank was z34 specific so i guess they werent really making a ton of money because it was specific, rather than the tank now is compatible with the 350z, 370z, g35, g37.... less labor more money i guess
