there's threads on the Mizu radiator which says basically 'Yeah' and theres some odd thread I found about the Mizu fan should and fans, but there's not actually any feedback in it about one actually fitted to the RX-8. My car is now showing classic main fan failure symptoms and a change of radiator was on the list for this year anyway... so I'm thinkin to just go the Mizu and replace the OEM fans with their fan kit.- - hecne the request for feedback from anyone with this actual setup.

Alternative # 2 is the Mizu radiator and the S2 fans and shroud but that's quite a bit more money.
