Description
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.
Why Upgrade from the Factory CT26?
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.
Why the 18G is the Performance Choice for 1HD-T Owners
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.
16G vs 18G — Which Should You Choose?
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.
