Description
This Platinum Series piston family targets Nissan GT-R 3.8L VR38DETT engine combinations and should be selected from the finished-bore specification rather than from vehicle fitment alone. The parent listing is distinguished by 95.5mm / Part #633EGR3-1, 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.
