I happened to speak to Ross this morning and asked him about the status of his turbo kit. He indicated that he hadn't released Version 1, even though he had thorougly tested it (on a vehicle, putting on about 5000 miles with no problem). Issue as I understood him was that due to the design of exhaust fitting into the turbocharger, the unit wasn't generating as much boost as he wanted. He has redesigned and is just about to take delivery of the prototype Version 2 unit -- which he will fit to a car and test this Spring. He is hoping for 5-6 lbs. of boost. If all goes well, the "kit" will be available in July or August. It should be usable for 302 Mustang engines & Explorer engines (right up to 2004). He's sorry that it's been delayed, but he says he'll return calls from interested parties. Usually one has to leave a message. Best to give him a few specific times to call you back.
