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.
