Nitto Forged Pistons Nissan RB30 DOHC RB25 NEO Head Conversion

Nitto Forged Pistons - Nissan RB30 DOHC - RB25 NEO Head Conversion

Built for RB30 bottom ends running the RB25DET NEO cylinder head, these Nitto forged pistons keep the standard RB30 stroke. They suit turbo street cars and weekend drag or circuit builds using the NEO head.

Both sizes use a 2 cc dish. Choose 86.5 mm (+0.020") or 87.0 mm (+0.040") to match your bore.

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.
