Description
Manley developed this Extreme Duty piston configuration for Nissan GT-R 3.8L VR38DETT 95.5mm; use the listed bore and compression details to match the piston to the finished cylinder and intended rotating assembly. The selectable configurations in this family are separated by piston grade, so the final SKU should be chosen from the dimensional requirements of the build.
For Nissan GT-R 3.8L VR38DETT 95.5mm builds, piston grade and bore size should be treated as measured engine-build specifications. Confirm the matching cylinder and any required piston-to-wall clearance before assembly.
