If you’re considering tuning your Nissan TB48 engine, you should know about the variable intake system. This system, labeled VIAS by Nissan, works by switching on a solenoid and providing a vacuum to a diaphragm. This diaphragm opens the intake control power valve at the correct rpm. It typically opens at 2000rpm and closes at 3600rpm. However, the Nissan TB48 ECU is not compatible with Elite 550/750/950 ECU models. If you want to use this system, you should add a Haltech Air Temp Sensor.
Nissan TB48DE straight-six engines are a great choice for performance vehicles and a popular upgrade for Nissan vehicles. This engine has a 4.8-liter displacement and is available in both manual and automatic transmissions. In automatic transmission versions, the throttle body uses an electronic control system while manual transmission models use a cable-operated throttle body and position sensor. While manual transmission TB48 engines do not come equipped with a MAP sensor, you can install a MAP sensor if you wish to increase boost levels. If you choose to install an external MAP sensor, make sure to connect it to a spare AVI. This engine also features a variable inlet camshaft. It is disabled at low Rpm but enabled in mid-range and high-rpm conditions.
The Nissan TB48DE is a straight-six engine that puts out 185kW of power and 420Nm of torque. Its design allows it to operate under very high loads and is capable of towing horse floats and other large objects. Nissan has also modified this engine to give it a better performance.
Using the right valvetrain can help make your engine run more efficiently. The Nissan TB48DE uses a variable intake system (VIAS) that provides variable rpm and boost levels. The ECU controls a solenoid that supplies vacuum to a diaphragm, which opens an intake control power valve. Typically, the valve is switched on around 2000 rpm, and off at around 3600 rpm. To get the most benefit from the valvetrain, you’ll need to use a Nissan TB48E ECU with a Haltech Air Temp Sensor.
TB48DE valves are made of the same high-grade Supertech materials as the rest of the valvetrain. These materials are designed for high-revolution motors and have a smooth, tempered surface finish. This ensures superior durability, and a smooth, low-friction operation.
TB48DE exhaust system
If you’re in the market for a new exhaust system for your Nissan, you’ve come to the right place. Performance Exhaust Nationwide p/l manufactures a high-quality exhaust system for Nissans. This system is engineered to add power, torque, and fuel mileage. It features premium band clamps for added stability and a 360-degree sealing surface. Its muffler is also made of stainless steel and features a 22-inch free-flow design.
TB48DE intake system
Nissan TB48DE intake systems are designed for full-chassis drag cars and street/strip conversions. They are not designed for use on Nissan Patrols and require extensive engine bay modification. The TB48DE features a variable inlet system (VIAS) that uses a solenoid to provide vacuum to a diaphragm. The diaphragm then opens the intake control power valve, typically at 2000 rpm and closes at 3600 rpm. It is not a direct fit for Nissan Patrol models and requires a considerable amount of engine bay modifications, including relocation of other engine bay items.
If you are looking for Nissan TB48DE valves, you’ve come to the right place. These new valves are made with the finest materials for maximum performance and durability. The black nitride coating on these valves helps minimize friction in the internal engine. They are also CNC milled for exact fitment and long life.
If you’re planning on revving your Nissan TB48DE, you should start by checking the valve guide size. Then, you can choose the valves based on their recommended RPM range. This is an excellent way to improve horsepower at higher RPM. If you’re looking to add more performance, you can go for one-piece titanium alloy valves. These valves come with Supertech spring retainers and keepers.
