Ct20 turbo

Types of CT20 Turbos

A CT20 Turbo refers to a turbocharger that is commonly used in Toyota 1JZ-GE, 1JZ-GTE, 2JZ-GE, 2JZ-GTE, 2L, 2LT, 3L, 3S-GE, and 4A-GE engines. These engines are typically found in Toyota Crown, Chaser, Mark II, Aristo, Camry, Celica, and Supra models. The CT20 turbo is an OEM turbocharger, meaning it is a part that was made by Toyota for use in some of their older models. The CT20 turbo was used in many factory models up until the mid-2000s. After that, many of these engines were discontinued, and the CT20 turbo fell into disuse.

The CT20 turbo is a popular choice for engine modification because it is a reliable and efficient turbocharger. It is also a good option for those looking to increase the performance of their engines without going for an aftermarket turbo. The CT20 turbo is capable of providing a significant boost in power and torque. It is a good choice for both daily drivers and weekend warriors. There are different variants of the CT20 turbo, which include the Toyota CT20 turbo A, B, C, and Toyota Turbo CT20B, CT20, CT201, and CT201B. They all differ in specifications, such as the turbine and compressor wheel sizes.

  The CT20 turbo uses a journal bearing system, and the bearing diameter is 10.0 mm. The bearing system supports the shaft and allows smooth rotation.

• Oil feed and drain ports:

  The CT20 turbo oil feed port and drain port diameter are 6.0 mm and 8.0 mm, respectively. The oil ports allow oil supply to the bearings and oil drainage from the turbo.

Maintaining the CT20 turbocharger is crucial for ensuring its longevity and optimal performance. Here are some key maintenance tips:

• Quality oil:

  Using high-quality engine oil is essential for the turbo's health. The oil lubricates and cools the turbo, reducing friction and wear.

• Regular oil changes:

  Changing the engine oil regularly prevents the buildup of contaminants that could damage the turbo.

• Proper cool-down:

  Allowing the turbo to cool down before turning off the engine is important. This practice prevents turbo coking, extending the turbo's lifespan.

• Quality aftermarket intakes:

  Investing in high-quality aftermarket intake filters is essential. The intake filters ensure proper airflow to the turbo while preventing debris entry that could damage the CT20 turbo.

• Regular inspections:

  Regularly inspecting the oil lines, wastegate, and other turbo components for wear or damage is essential. Early detection allows for timely repairs, preventing further damage.

How to Choose CT20 Turbo

Selecting the right CT20 turbo for a vehicle is a critical choice that can fundamentally influence execution, productivity, and generally speaking driving experience. Here are a few elements to consider while choosing the right CT20 turbo for particular necessities:

• Understand the engine:

  One should understand their vehicle's motor. Knowing the motor's kind, limit, and alterations will assist with coordinating with the CT20 turbo's qualities to the vehicle's necessities.

• Determine goals:

  What does one need to get from a turbo help? Is it true that one is searching for more top-end power, snappier speed increase, or a fair balance? Understanding these objectives will assist with directing the choice cycle.

• Consider vehicle use:

  For a ct20 turbocharger, constant power delivery is required for towing or hauling large loads. In contrast, a smaller turbo may suffice for a car used primarily for commuting in city traffic.

• Evaluate brand and quality:

  Choosing a reputable brand known for quality and dependability is significant. Peruse audits, look at rankings, and request proposals to distinguish trustworthy ct20 turbo venders.

• Check compatibility:

  Not all turbos are compatible with every engine. Ensure the CT20 turbo chosen is designed for the specific engine and its modifications, if any.

• Consider supporting systems:

  The exhaust, intake, and intercooler are all vital to a turbo's performance. Ensure these systems are adequate to support the chosen turbo and that they are in good condition.

• Set a budget:

  A ct20 turbocharger can vary significantly in price. It's crucial to set a budget before shopping. Remember that a more expensive turbo may provide better long-term value through performance gains and engine efficiency.

How To DIY and Replace Ct20 Turbo

Replacing a CT20 turbo is a simple task that can be carried out by following the steps below. First, gather all the necessary tools for the job. This includes a socket set, wrenches, a torque wrench, an oil drain pan, new gaskets and seals, and possibly a boost gauge. Then, follow these steps:

• Remove the old turbocharger: Start by disconnecting the negative battery cable. Then, drain the engine oil and coolant. After that, remove any air intake piping connected to the turbo and disconnect the wastegate actuator rod. Finally, loosen the turbo-to-exhaust manifold bolts and the turbo-to-downpipe bolts and use a lift or jack to support the vehicle and access the turbo.
• Prepare the new turbocharger: Before installing the new turbo, ensure that it is properly lubricated and primed according to the manufacturer's instructions. Use clean engine oil to lubricate the bearings of the turbocharger. Also, ensure that all gasket surfaces on the engine are clean and free of debris.
• Install the new turbocharger: Position the new turbocharger onto the exhaust manifold, ensuring proper alignment. Install the turbo-to-exhaust manifold and turbo-to-downpipe bolts with the specified torque using a torque wrench. Then, connect the oil feed and oil drain lines to the turbo and ensure they are properly tightened to prevent leaks. After that, reconnect the air intake piping to the turbocharger, ensuring a secure fit and proper sealing. Also, connect the wastegate actuator rod to the wastegate.
• Final steps: Reconnect the negative battery terminal and refill the engine oil and coolant. Start the engine and check for any leaks or unusual noises. Also, ensure the wastegate actuator operates smoothly.
