Toyota Racing Development

Toyota Racing Development (also known by its abbreviation TRD) is the in-house tuning shop for all Toyota, Lexus and formerly Scion cars. "TRD" is responsible both for improving street cars for more performance and supporting Toyota's racing interests around the world. TRD produces various tuning products and accessories, including performance suspension components, superchargers, and wheels. TRD parts are available through Toyota dealers, and are also available as accessories on brand-new Toyotas and Scions. Performance parts for Lexus vehicles are now labeled as "F-Sport" and performance Lexus models are labeled "F" to distinguish Lexus's F division from TRD.
 there are currently two official branches of TRD: TRD Japan (a.k.a. Toyota Technocraft) and TRD USA. Each of these branches has both a performance tuning division and a race (or competition) division. 
TRD Japan's Race Division concentrates on the Super GT Series (JGTC), All-Japan Formula Three Championship Series, ESSO Formula Toyota Series, and Netz Cup races (Vitz and 86/BRZ Race Series). Many of these activities has been rebranded under the Toyota Gazoo Racing brand.
TRD USA's Race Division, known as 'Toyota Racing', competes in NASCAR, NHRA Top Fuel and Funny car, IMSA GT Daytona, Pirelli World Challenge TCA, Formula Drift, , USAC, and Lucas Oil Off Road Racing Series. Former competitions include the Baja 1000, Grand-Am, CART/Champ Car and the Indy Racing League. In association with All American Racers, TRD USA was responsible for developing engines for the Eagle HF89/90 and Eagle MkIII Grand Touring Prototypes.
TRD is not to be confused with Toyota Motorsport GmbH (TMG), which is located in Cologne, Germany and currently operates Toyota's FIA World Endurance Championship (WEC) factory team under the name Toyota Gazoo Racing. Within Toyota, TMG is a completely separate entity from, and therefore not under the control of, TRD. Former TMG activities include operating the Toyota Formula One Team (also known as Panasonic Toyota Racing), which competed in the FIA Formula One World Championship (F1). TMG also competed in the FIA World Rally Championship (WRC) as Toyota Team Europe with the famous Celica GT-Four and rally versions of the Corolla, and two attempts (in 1998 and 1999) at the 24 Hours of Le Mans with the GT-One.
Toyota Australia introduced a TRD division in August 2007, with the supercharged Aurion V6, followed by a high-performance variant of the 4WD Hilux in April 2008. Speculation suggested a third model was likely to be a RAV4. TRD was aimed to compete with local in-house tuning shops Holden Special Vehicles (HSV) and Ford Performance Vehicles (FPV). However, in December 2008 Toyota Australia announced it would be ceasing production of its TRD range. The decision took effect on 31 March 2009.

TRD supercharged engine list.
When install is performed by a Toyota dealer, the 3/36,000 mile warranty extends to the supercharger, otherwise the vehicle retains the factory warranties and the supercharger is covered by a 12 month/unlimited mileage warranty. As of 2015 all TRD Superchargers have been discontinued and ceased production, but all warranties will still be acknowledged.
