Nitto Forged Stroker Pistons Nissan RB25DET NEO Skyline (R34) / Stagea (WC34)

Nitto Forged Stroker Pistons - Nissan RB25DET NEO - Skyline (R34) / Stagea (WC34)

A set of six forged pistons for building a 2.8-litre RB25DET NEO, as fitted to the R34 Skyline GT-T and series 2 Stagea. They are designed to run with a 77.7 mm stroke crankshaft, giving more capacity and response for a high-power street, drag or circuit build.

These pistons come in one size: 86.5 mm, a 0.020" oversize, for a 77.7 mm stroke. They use a 0.866" wrist pin, so check that your connecting rods suit before ordering.

Every Nitto piston is produced by CP Carrillo in the USA to Nitto's own specification. They are forged from CP's low-silicon 2618 alloy in the Turbo HD forging, paired with a PVD-coated ring set for tight bore sealing under boost, and fitted with CP's 9310 wrist pins, which are Rockwell tested, case hardened and cryogenically treated.

Note: Installation by a professional is recommended. Engine internals must be measured and set up by a qualified engine builder.
