Toyota Racing Development
Toyota Racing Development (TRD) introduced a supercharger for the 3.4-liter engine in 1996 and it became available for the T100, the Tacoma and the 4Runner with the 3.4-liter V6 (and later the Tundra). Horsepower jumped to the range (depending on the generation of the supercharger) and to of torque. This power add on was available for 1997–1998 T100s only. Earlier 3.4 V6 powered T100s have different computer and electrical layouts which do not support the TRD device.
