Collection: For TD42 Bolt-on Water-Cooled

Engineered for later model GU Nissan Patrol TD42 4.2L diesel with low-mount water-cooled configuration. Our streamlined selection features only the most proven anti-surge configurations for reliable off-road performance.

Why Water-Cooled Configuration?

Later model GU Patrol (post-2000) came factory-equipped with water-cooled turbo configuration. Our turbos are specifically designed to bolt directly to your water-cooled manifold with proper coolant routing for optimal reliability.

Choose Your Power Level:

🎯 ANTI-SURGE TD05H-18G - POWER OPTION

• ✅ 200-250HP capacity - Optimal power for 4.2L TD42
• ✅ Anti-surge protection - Critical for off-road throttle transitions
• ✅ 6cm turbine housing - Quick spool with strong mid-range
• ✅ 3" inlet - Suck more airflow for better response.
• ✅ Water-cooled design - Direct replacement for factory configuration

🛡️ ANTI-SURGE TD05H-16G - CONSERVATIVE OPTION

• ✅ Up to 200HP capacity - Perfect for daily driving and moderate touring
• ✅ Anti-surge protection - Reliable off-road performance
• ✅ Faster spool than 18G - Better low-end response and torque
• ✅ 3" inlet - Suck more airflow for better response.
• ✅ Ideal for stock engines - Conservative power gains with maximum reliability
• ✅ Equally popular - Customers split 50/50 between 18G and 16G

💰 STANDARD TD05H-18G - BUDGET OPTION

• 200-250HP capacity without anti-surge technology
• Best value for highway and touring applications
• Bolt-on fitment with 6cm housing and 3" inlet
• Suitable for less demanding off-road use
• Water-cooled design matches factory configuration

18G vs 16G - Which Should You Choose?

Choose 18G if you want:

• Maximum power (200-250HP)
• Strong mid-range and top-end performance
• Best for highway cruising and towing heavy loads
• Optimal for modified engines with supporting mods

Choose 16G if you want:

• Conservative power (up to 200HP)
• Faster spool and better low-end torque
• Best for rock crawling and technical off-road
• Ideal for stock or lightly modified engines

Both are equally popular - our customers are split 50/50 between these two options. You can't go wrong with either choice!
