Supra (A80)

1993-2002 / Coupe / Japan

Minor Engine, 2JZ-GTE (Twin Turbo)

Timing Belt Failure

Symptoms

Catastrophic engine damage. The 2JZ is an interference engine, if the timing belt breaks, the pistons strike the open valves, bending them and potentially damaging the pistons, head, and block. The engine stops instantly and will not restart.

Cause

The timing belt is a rubber component with a finite service life. Toyota specifies replacement every 100,000 km or 7 years. Many A80s have changed hands multiple times, and the timing belt service history may be incomplete or unknown.

Fix

Replace the timing belt, water pump, belt tensioner, and both idler pulleys as a set.

Do not replace just the belt, the tensioner and idler bearings have the same service life and a failed tensioner will throw the belt.

Use genuine Toyota or Gates Racing parts.

Cost: $800-1,500 including parts and labour.

This is a moderately involved job (6-8 hours) that requires removing the front of the engine.
