Source figures from JBugs VW Engine Torque Specifications. Nm values are converted from manufacturer ft-lb specs (1 lb-ft ≈ 1.356 Nm) — where the source lists a range, the note column shows the original ft-lb range.

Conversions are rounded (1 Nm ≈ 0.7376 lb-ft). Always torque in the correct sequence and in stages. Verify against your engine builder's instructions for performance or modified assemblies.
