I'd also assume that the specs are inline with the 120v version as the impeller would be the same and an appropriate DC motor would be selected by Iwaki so that it achieves the same RPM as the AC version. This seems like the most efficient means of modifying the pump for the manufacturer. Price is anyone's guess. I'd be interested for $150. Pair one of those with a Swiftech Storm and a decent rad..... gosh that makes my setup seem obsolete
