NISSAN RB30E / RB30ET ENGINE KIT
Build It. Understand It. Display It.
Recreate one of Australia’s most recognisable straight-six engines with the Nissan RB30E / RB30ET Engine Kit.
Best known for powering the iconic Holden VL Commodore, the 3.0-litre SOHC RB30 became a favourite of Australian enthusiasts in both naturally aspirated and turbocharged form.
Built entirely from 100% genuine LEGO® elements, this detailed miniature lets you choose between the classic naturally aspirated RB30E, the factory-style turbocharged RB30ET, or a modified RB30ET equipped with a front-mount intercooler.
WHAT YOU’LL BUILD
A detailed scale model inspired by the Nissan RB30 3.0 L SOHC inline-six, featuring a functional internal assembly and configuration-specific external details.
Choose the naturally aspirated RB30E with its distinctive grey rocker cover, or step up to the RB30ET with its iconic red rocker cover, turbocharger and your choice of factory-style or front-mount intercooler intake system.
