The Supras twin-sequential turbos provide snappy response at low RPM and prodigious output at increased speeds. During low-RPM operation one turbocharger is optimised for early boost to improve response and torque from a standing start. In the midrange the second turbo comes on for a smooth transition from the primary to the secondary turbocharger until both turbos operate at full boost. Toyota chose to use a serpentine belt-drive system to power engine accessories which are attached directly to the cylinder block instead of to brackets. Aluminum engine mounts also save weight. In 1997 extreme weight reduction measures used hollow carpet fibers and a hollow rear spoiler. The Supra Turbo still weighed in at close to 3500 lbs. The 2JZ-GTE like its smaller capacity cousin the 1JZ has proven to be built to withstand the rigors of high power output without the need to resort to internal aftermarket components unless venturing above the 500hp mark.
