If you do a search you'll find this has been discussed on a few occasions. Bottom line is unless you can get EVERYTHING that is required to run the Eaton on your car for a really cheap price you'll;l end up spending as much if not more than just going with a purpose built KB kit from the start. The eaton, all of it's cooling parts, the EEC, the 03/04 hood, etc... it's would be very expensive...
