Description
Manley developed this Extreme Duty piston configuration for Nissan GT-R 3.8L VR38DETT; use the listed bore and compression details to match the piston to the finished cylinder and intended rotating assembly. The parent listing is distinguished by 95.5mm, which should be cross-checked against the rest of the engine combination.
Because this is a Nissan GT-R 3.8L VR38DETT piston family, final fitment depends on the machine shop’s finished cylinder measurement and the intended rod/stroke combination—not simply on nominal engine displacement.
