JE forged piston sets for the Nissan GT‑R R35 are engineered specifically for the VR38DETT engine and designed around the factory 95.50mm bore. These pistons are intended for use in standard-size cylinders, allowing the factory plasma‑sprayed bore coating to remain intact when the cylinder walls are confirmed to be in good condition.

Two compression ratio options are available, allowing you to tailor your build for high-boost reliability or increased response and efficiency. Listed compression ratios are based on factory deck machined surfaces and the use of 0.037" thick JE Pro Seal Sport Compact head gaskets.

Available Options

• Part No. 321269 – 9.0:1 compression ratio
  (Calculated using 0.037" Pro Seal Sport Compact gaskets: NI1005‑037 (RHS) & NI1004‑037 (LHS))
• Part No. 321270 – 10.0:1 compression ratio
  (Calculated using 0.037" Pro Seal Sport Compact gaskets: NI1005‑037 (RHS) & NI1004‑037 (LHS))

Important Note

• Any change in head gasket thickness, cylinder block decking, or cylinder head resurfacing will affect the final compression ratio.
