Nitto Forged Pistons Nissan RB30 DOHC RB25 / RB26 Head Conversion

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

These Nitto forged pistons are for the popular RB30 "RB30DET" combination, where an RB30 bottom end is paired with an RB25 or RB26 twin-cam head. They keep the factory 85 mm stroke and suit turbo street, drag and circuit builds that need a strong forged piston.

Pick the bore size to match your block: 86.5 mm (+0.020") with a 12 cc dome, or 87.0 mm (+0.040") with an 11 cc dome.

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.
