Vehicle Applications

• Nissan Skyline GT-R R32
• Nissan RB26DETT engine applications

Protect your legendary Nissan Skyline GT-R R32 RB26DETT engine with the Radium Engineering Dual Catch Can Kit (20-0590-FL). Designed specifically for the RB26 platform, this complete closed-loop catch can system helps remove oil vapor, fuel residue, and moisture from crankcase ventilation gases before they are recirculated into the intake system.

The Radium Dual Catch Can Kit maintains the factory-style PCV and crankcase ventilation strategy while improving engine cleanliness, reducing intake contamination, and supporting optimal crankcase pressure control. Unlike open vent-to-atmosphere systems, this closed-loop design keeps unwanted oil vapors contained while remaining suitable for both street and track applications.

Featuring Radium’s advanced Fluid Lock® Catch Can technology, this system helps prevent collected contaminants from being pulled back into the intake system if the catch can becomes overfilled. The result is improved reliability, cleaner intake components, and better protection for high-performance RB26DETT builds.

Product Features

• Dual catch can design for PCV and crankcase ventilation systems
• Closed-loop system (not vent-to-atmosphere)
• Helps prevent oil buildup in intake components
• Maintains proper crankcase ventilation operation
• Improves intake system cleanliness
• Supports high-performance and high-boost applications
• Designed for street and track use

Advanced Fluid Lock® Catch Can Technology

Radium Engineering’s Fluid Lock® system addresses a common issue found in traditional catch cans: collected fluid can eventually migrate back into the intake system if the reservoir becomes saturated.

The Fluid Lock® design helps contain collected oil and moisture until servicing is required, protecting the intake tract and maintaining consistent engine performance.

Benefits include:

• Prevents fluid ingestion from overfilled catch cans
• Protects turbochargers and intercooler systems
• Reduces intake manifold oil contamination
• Improves long-term engine reliability

System Design and Function

The Radium Dual Catch Can Kit includes dedicated catch cans for both sides of the RB26DETT ventilation system.

PCV Catch Can

The PCV catch can installs inline between the valve cover ventilation system and the PCV valve. During idle, cruising, and deceleration conditions, it captures oil vapor, fuel residue, and moisture before those contaminants enter the intake manifold.

Benefits:

• Reduces intake manifold contamination
• Maintains proper PCV operation
• Helps maintain cleaner combustion conditions

CCV Catch Can

The crankcase ventilation catch can installs between the valve cover vents and turbo inlet system. During high-load and wide-open-throttle operation, it captures oil vapor before it reaches the intake tract.

Benefits:

• Keeps intercooler piping cleaner
• Reduces oil accumulation in intake components
• Supports improved charge air efficiency

Included Components

The Radium Dual Catch Can Kit includes:

• Dual baffled catch cans with dipsticks
• Nissan-specific mounting brackets
• RB26DETT valve cover press-fit fittings
• 10AN adapter fittings and hose ends
• Radium 5/8" PCV hose
• Stainless steel mounting hardware

Specifications

• Catch Can Capacity: 7 fluid ounces each
• Inlet/Outlet Ports: Large 10AN ORB fittings
• Drain Port: 4AN ORB
• Oil Separation: Two-stage baffling system
• Inspection: Integrated O-ring sealed dipsticks
• Installation: Direct-fit design with no drilling required

Why Choose the Radium Dual Catch Can Kit for Your RB26DETT?

The RB26DETT is capable of producing substantial horsepower, but increased boost pressure and engine load can significantly increase crankcase pressure and oil vapor production. A properly designed catch can system becomes essential for maintaining engine performance and protecting expensive components.

The Radium Dual Catch Can Kit provides a complete solution by separating oil and moisture before contaminants can enter the intake system.

Benefits include:

• Cleaner intake manifold and intercooler system
• Reduced oil vapor contamination
• Improved engine reliability
• Proper closed-loop crankcase ventilation
• Better protection during high-boost operation
• Professional motorsport-quality installation
