If you really want those, search ebay for "300zx Godspeed" and you'll find some for much cheaper, about $350 shipped. I'm really not sure about their performance but i do know those are flippin huge. I think only Ash's Massives have a bigger core size that i know of. Again i have no idea about how these perform, but i would stick to more proven intercoolers (e.g. Z1, greddy, etc.). Size isn't everything...
