Upgrading to a larger turbo and making supporting modifications is one of the top power-boosting choices you can make. Blouch, a pioneer in turbo development, always builds top - notch turbos. Their new XT - R series of turbos features a billet compressor wheel. This design optimizes the turbo's aerodynamics and boosts compressor flow within the same inducer geometry, enabling you to generate more horsepower at lower boost pressure. It comes with a 43 lb/min fully - machined billet compressor wheel, a high - efficiency Garrett GT turbine wheel, a Garrett GT full ball bearing system, and an 8cm² bolt - on turbine housing. This turbo is suitable for Subaru WRX/STi and can achieve up to 430HP. Specifications include a Garrett Ball bearing CHRA, a 56.5mm turbine wheel, a 68mm XT compressor wheel, a flow rate of 43 lbs per minute, and options of 8cm or 10cm exhaust housing. The turbo package includes water pipes, an oil feed line, turbine inlet and outlet gaskets, and a ported exhaust housing.
Using this Blouch 18GXT - R turbocharger is straightforward. First, make sure your Subaru WRX or STI engine is turned off and cooled down. Then, carefully install the turbo using the included water pipes, oil feed line, and gaskets. Connect everything according to the engine's layout. When starting your car after installation, let it idle for a few minutes to allow the oil to circulate properly through the turbo. As for maintenance, check the oil level regularly as the turbo relies on proper lubrication. Also, keep an eye on the exhaust housing for any signs of damage or wear. If you notice any strange noises or a decrease in performance, it's a good idea to have the turbo inspected by a professional. Remember, don't push the engine too hard right after starting it up, especially in cold weather. Let the turbo and engine warm up gradually for better performance and longevity.
