Toyota 2jz Gte Head Bolt Torque Specs
| APPLICATION / ITEM | SPECIFICATION | NOTES |
|---|---|---|
| Initial torque | 34 N·m (25 lb-ft) | Several passes; oiled factory bolts |
| Angle pass 1 | 90° | Follow the 14-bolt sequence |
| Angle pass 2 | Additional 90° | Paint marks finish toward the rear |
| Plate washers | 14 required | Install under every bolt head |
| Aftermarket studs | Stud-maker procedure | Factory angle stages do not apply |
Install all 14 plate washers, lightly oil the threads and under-head surfaces, reach the initial torque in several passes, then paint-mark the bolt heads before both angle stages. Replace any bolt that breaks, deforms or cannot meet the initial torque requirement.

Toyota 2JZ-GTE Head Bolt Torque Specs and Sequence FAQs
What is the head bolt torque on a 2JZ-GTE?+
The 1997 Toyota Supra repair manual specifies 34 N·m (25 lb-ft) for the oiled factory bolts, reached in several passes, followed by 90° and another 90° in the illustrated 14-bolt sequence.
Are the plate washers required?+
Yes — all 14, one under every bolt head. They are part of the specified joint, not an optional part.
When should a 2JZ-GTE head bolt be replaced?+
Replace any bolt that breaks, deforms, or cannot meet the initial torque requirement.
How do I verify the angle stages?+
Paint-mark the bolt heads before both angle turns; when the procedure is complete the marks finish toward the rear. Aftermarket stud kits do not use the factory angle stages at all — follow the stud maker's procedure instead.
