Post was already way to long, but this is of interest, from Wiki in regards to the Tacoma TRD supercharger.

Oh please let them release it as a kit and covered by warranty, it'd keep the early adopters happy plus bring in the business for the dealerships.

Toyota Racing Development offers a TRD supercharger for the FJ Cruiser and Tacoma equipped with 4.0-liter V6 engine, available through Toyota dealerships. The supercharger increases the Tacoma's power output to 304 hp (227 kW) from the original 236, and the torque output to 334 lb·ft (453 N·m).[10]

This all-new TRD supercharger is compatible on all 2005 through 2009 model year Toyota Tacoma trucks, and 2007 and 2009 model year FJ Cruiser SUV. This supercharger system features Eaton roots-type rotating components in a one-piece integral manifold, iridium spark plugs, and a five-rib serpentine drive belt system. It produces six to eight pounds of boost pressure per square inch.

The supercharger, when installed by an authorized Scion or Toyota dealer, has the same warranty as powertrain, five years or 60,000 miles (97,000 km), or the balance of the new car warranty, whichever is greater. When not installed by an authorized dealer, the supercharger is covered by a 12-month, 12,000-mile (19,000 km) parts-only warranty. The manufacturer's suggested retail price of the TRD supercharger is $4,500, not including installation.
