Thought I’d had these posted but realised I hadn’t, this is the 2005 IS300 workshop manual pages. These come in handy for the VVTi guys due to the VVTi head torque and specs, most apply to the 2JZGE and 2JZGTE VVTi figures.
Most of these documents are applicable to the J-SPEC and Europe-SPEC supras. There might be differences to driving side, wiring and some features and functions.
