The Kinugawa TD05H-18G is designed and built to suit the 1HD series of motors found in the 75, 79, 80, 100 & 105 series LandCruiser. It utilizes the same flange as the factory CT26 turbo, meaning it bolts directly onto the stock exhaust manifold — no custom fabrication required. However, you will need to modify your induction pipe to suit the new 4" turbocharger inlet.

The factory CT26 turbocharger on the 1HD-T is notorious for snapping the turbine shaft when boost pressure exceeds 14psi — a real risk on engines that are now 30+ years old. The TD05H-18G is the definitive bolt-on replacement that eliminates this weakness entirely, while opening the door to serious power upgrades.

Based on real-world builds and dyno-proven results, the TD05H-18G is the recommended turbo for 1HD-T owners targeting 200HP+ and beyond. Here's why it stands out:

• Handles over 250HP — The 18G is rated beyond what the 1HD-T engine can physically produce, meaning you'll never outgrow this turbo. Upgrade your injector pump down the track without buying another turbo.
• Extremely responsive for its size — Despite its larger flow capacity, the 18G remains highly responsive and delivers strong low-end torque, making it ideal for both on-road and off-road use.
• Bolt-on fitment — Uses the CT26 turbine housing flange, so it bolts straight to your stock exhaust manifold and dump pipe. No custom work required.
• Proven power gains of 60–90%+ — In conjunction with an intercooler, 3" exhaust, and injector pump tune, builds targeting 200HP+ are well within reach. With an upgraded fuel pump, up to 240HP / 680NM is achievable.
• Future-proof upgrade path — The 18G supports the full power range of the 1HD-T platform. Whether you're at Stage 2 now or planning a Stage 3 fuel pump upgrade later, this turbo grows with your build.
• No water lines required — Simplifies installation compared to OEM-style setups.
• Signature 4" anti-surge inlet — Produces the distinctive turbo whistle that sounds great on the 1HD-T engine.

If you're targeting up to 190HP and want the best possible boost response, the 16G is the pick. If you want maximum power potential (200HP–240HP+) and a future-proof platform that won't need replacing as your build evolves, the 18G is the right choice.
