I checked thoroughly a couple of years ago. Neither one then made - or now makes - a kit for the 3.0L 12v.

Either Alpine or C.A.P.A. once made an Eaton 62 blower kit for the Gen2 3.0L (would not work on the Gen1s) and the other once made an Eaton 62 blower kit for the 3.5L. A check of both sites now indicates nothing is available for Mitsubishi vehicles.

Ripp once made a 3.0L Gen1 centrifugal blower kit, but it sure was an ugly mess.... fairly simple, though.

If you want one, you'll have to go the custom route.
