Nitto Forged Stroker Pistons Nissan RB30 DOHC RB25 / RB26 Head Conversion

Nitto Forged Stroker Pistons - Nissan RB30 DOHC - RB25 / RB26 Head Conversion

Nitto's 3.2L stroker pistons suit RB30 bottom ends running an RB25 or RB26 twin-cam head with a 90 mm stroke crank. This combination is a favourite for high-power drag and street builds, and these are the same style of piston used in Nitto's RB30 3.2L kits.

Choose 86.0 mm (standard bore) or 86.5 mm (+0.020") with a 6 cc dome, or 87.0 mm (+0.040") with a 5 cc dome. All use a 0.866" wrist pin.

Nitto pistons are made by CP Carrillo to Nitto's own specification and are forged from CP's low-silicon 2618 aluminium in the Turbo HD forging. Each set comes with a PVD-coated ring set for strong bore sealing under boost, plus CP 9310 wrist pins that 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.
