RB30 Power Steering Pump to VK56 Conversion Upgrade Kit

Replace your RB30 power steering pump and bracket with a bolt-on adapter for a readily available VK56 pump. Whether you’re building an RB30DET or an RB30-based hybrid, this kit gives you an adjustable pump mount while retaining your existing power steering lines.

The bracket fits RB30, RB20DET, RB25DET, RB25DET NEO, and RB26DETT engines in supported R32, R33, and R34 Skyline applications.

Why upgrade your RB30 power steering setup?

• Easier pump replacement: Choose from aftermarket, OEM, or used VK56 power steering pumps instead of searching for an original RB pump.
• Single-stage pump: Simplifies the hydraulic setup on R32 builds with HICAS.
• Bolt-on installation: Replace the original pump and bracket using basic hand tools. No cutting or drilling is required.
• Adjustable belt routing: The pump can be positioned to share a belt with the A/C compressor. The included idler pulley increases belt wrap to help keep the belt engaged at high RPM.
• Built to last: The 8 mm steel bracket is powder coated black. Engineered, cut, and assembled in the USA.

Kit includes

• RB30-to-VK56 power steering pump adapter bracket
• Tensioner
• Idler pulley
• Installation hardware
• Installation instructions

Pump and belt are sold separately unless selected as options.

Optional upgrades

• VK56 power steering pump
• Belt
• Magnetic laser pulley alignment tool
• AN pump and rack fittings with PTFE power steering hose
• Reservoir hose adapter for R32 hydraulic HICAS cars retaining the factory reservoir

HICAS note: The single-stage pump removes the original pump’s hydraulic supply to HICAS. Completing a rear steering delete requires separate HICAS hardware and plumbing work.

Pump warranty: Optional power steering pumps carry the manufacturer’s warranty. We offer them so you can order the conversion parts together.
