This is a kit I got a while back offered by "Sam Dog" on m.net through BGL Enterprises. They dont offer the kit anymore but they do have the core:
It's a PWR 4x10" IC though I've had 2.5" inlet and outlet welded on (it was 2" I think) to match the rest of the system.
There's also a small summit racing cooler core and a Jabsco "Centri-puppy" high flow pump. And some random hoses and fittings if you want to add a surge tank.
Original price for everything was around $800 plus hoses. I've since upgraded to a BEGi air/air setup just to try something different. The pump isn't very loud if you mount it with the rubber grommets. No reason you can't use this on ANY car if not a miata. Here's an "installed" photo in my car... (click for larger)

And if you want I'l throw in the cast aluminum elbow for $15. It's pre-tapped for aquamist WI nozzles. I can also throw in BLUE silicone 2.5" connectors (no clamps) for $2.50 each... I have a few.
Asking $375 for the PWR 4x10 IC, Radiator Core, Centri-puppy pump, hoses and fittings shown above. Plus actual shipping and any paypal fees.
aluminum elbow: $15.00
blue connectors: $2.50 each
