ITALIANRP IRPPCD677-P CUSTOM PISTON 3.8L D95.53 MM (+/-95.50–95.58 MM RANGE) NISSAN GTR R35

VR38DETT Engine Architecture | ItalianRP Platinum Series Custom Pistons

High-output VR38DETT engines frequently encounter ring land failure and skirt deformation when cylinder pressures exceed factory safety margins during high-boost applications. The ItalianRP IRPPCD677-P Custom pistons are engineered to solve these structural bottlenecks by utilizing a proprietary high-silicon aluminum alloy that maintains superior dimensional stability at extreme thermal loads. This validated custom configuration addresses the mechanical problem of piston-slap and oil consumption by utilizing a high-precision 95.53mm bore size (+/-95.50–95.58mm range), providing a optimized clearance profile that ensures a perfect ring seal and maximum compression retention under 1,500+ hp loads.

The Platinum Line features a high-precision bridged-box forging, which increases structural rigidity without a significant mass penalty, effectively reducing parasitic reciprocating weight. This architecture is validated for extreme RPM stability, preventing the crown deflection typical of lesser forged components. By incorporating a specialized skirt coating and an optimized crown design for enhanced flame propagation, these pistons provide a high-precision solution for professional engine builders seeking to maximize the volumetric efficiency and longevity of the R35 GT-R power unit.
