This CT12B hybrid turbocharger for is designed for Toyota 3.0- TD, with a 125 hp capacity, and features d an internal modification designed for to adapt the compression capacity and d air flow.. Both available versions utilise a high-flow MFS compressor wheel, a 360° bearing retainer and high-speed balancing.
Documented applications include the Toyota 4 Runner and Land Cruiser fitted with 1KZ-T or 1KZ-TE engines. Compatibility must be confirmed using the original turbo part number d.
Available upgrades — Stage 1 and Stage 2+
Stage 1
Compressor wheel: MFS high-flow
Dimensions: 43.05 / 58.03 mm
Blade configuration: 11+0 Performance design
Bearing thrust: 360°
Balancing: high-speed at 150,000 rpm on a Cimat VSR test bench
This set-up combines a high-flow MFS compressor wheel with a specific blade configuration. It is designed to alter the compressor’s aerodynamic behaviour and its air-moving capacity, without affecting the engine’s final power output.
Stage 2+
Compressor impeller: high-flow MFS oversized
Dimensions: 47.10 / 62.00 mm
Blade configuration: 6+6 Snake Performance
d housing: Inlet: re-profiled for to accommodate the impeller oversized
Bearing stop: 360°
Balancing: high-speed at 150,000 rpm on a Cimat VSR test bench
Stage 2+ features a larger-diameter impeller and an intake housing d that has been reprofiled accordingly. This combination can increase flow capacity, but it may also alter the response time and the optimal operating conditions d for the turbocharger.
What is a hybrid turbo?
A hybrid turbo retains a turbocharger architecture designed for to accommodate modified internal components. Depending on the modification, changes may involve the compressor wheel, its dimensions, the blade geometry, the housings, the thrust bearing or the balancing.
The aim is d to adapt the compression capacity and air flow rate d to the requirements of the engine tuning. A hybrid turbo is therefore not defined solely by the appearance of its compressor wheel, but by the consistency of its mechanical and aerodynamic characteristics.
MFS compressor wheel: standard or ‘ Performance ’?
MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. This manufacturing process alone does not guarantee an increase in air flow d. A standard MFS wheel may retain a geometry equivalent to that d of the original.
An MFS impeller Performance can be given a geometry tailored to the intended application, for example a specific profile, diameter or blade configuration, provided these elements are documented. A standard MFS impeller can be just as polished as an MFS impeller Performance. It is not its appearance that determines its performance, but its geometry and its ability to move more d air.
A higher airflow d can enable the engine to produce more power with suitable engine management and components, though this alone does not guarantee a gain.
Why does the geometry of the blades influence the air flow rate d?
The compressor impeller draws in and then compresses the air sent to the engine. Its diameter, profile, height, width and blade arrangement influence the aerodynamic behaviour of the compressor. A suitable geometry can move more d air under certain operating conditions.
The result also depends on the compressor housing, the turbine section, the boost pressure and the engine set-up. A larger impeller does not automatically guarantee better performance and may alter the turbo’s response time.
Reliability and balancing of the hybrid turbo
The 360° bearing thrust ring, documented in both stages, helps to distribute the axial forces borne by the rotating assembly. It must operate with proper lubrication and does not make the turbocharger immune to fitting faults or d'oil supply issues.
Rotor balancing helps to limit vibrations and mechanical stresses at high revs. Each preparation presented has been d balanced at 150,000 rpm on a Cimat VSR test bench.
Engine remapping and tuning
Operating d'a hybrid turbo may require adjustments to the engine mapping, boost pressure and wastegate. Depending on the level of tuning, the fuel injection, exhaust system, intake air cooling d, clutch or transmission must also be checked and, if necessary, adjusted.
A hybrid turbo does not automatically guarantee a power gain without appropriate tuning. Adjustments must be carried out by a competent professional, taking into account the vehicle and its intended use.

Fitting instructions
⚠️ WARNING — IMPORTANT BEFORE INSTALLATION
Identify and rectify the cause of the previous fault before d installing the turbo. Check the lubrication system, the oil supply and return d as well as the cleanliness of the pipes.
Check the intake for foreign objects. Prime the system in accordance with the applicable recommendations and follow the manufacturer’s instructions. The wastegate must be adjusted during installation and when setting up the engine management system.
Unresolved lubrication issues may lead to further turbocharger failure.
How do you identify the correct turbo?
Check the part number marked on the original turbo d and compare it with the OEM part numbers and the CT12B type listed in this data sheet. Also check the make, model, generation, body style, engine type, power output, installation dates and engine code.
An identical engine specification does not always guarantee compatibility, as there may be several different set-ups depending on the vehicle and its production period.
⚠️ Check your turbo’s part numbers
Before ordering, compare the part number marked on your original d turbocharger with the part numbers listed in this data sheet. An identical engine specification does not always guarantee compatibility.
If in doubt, please contact us with the full part number taken from your turbocharger.
