993 head studs
I'm using the 993 head studs on my 2.7L 911 engine that has 11:1 JE pistons. I see that the 933 torque specs show that they're stretch bolts that are:
First stage: 20Nm (15ftlb.) Final stage: 1 x 90° +- 2° rotating angle Does anyone know what head nut torque I should use for my 2.7L engine application? Would that be too tight for my engine case and cylinders? My case has Case Savers. Thanks, Hipdoc |

That’s the same spec for a 3.2 Carrera
Seems tight for a magnesium case where the cylinder expansion and dilivar expansion is near the same. The mag case spec was always 25 ft#. Bruce |
