IPD 4T4 Turbocharger

Volvo uses a proprietary design for the exhaust manifold flange and outlet that made it necessary for us to manufacture a custom stainless steel exhaust housing from scratch rather than modifying a component from another car. Volvo also uses a low pressure TCV boost control system that will not work with most waste-gate actuators, requiring us to use our own specific billet actuator.

Our primary goal was to build the best possible solution for performance while allowing the use of intake and exhaust performance components that may have been previously installed by the tuner. Our larger more efficient ball bearing design allows far greater power output, at lower than stage 2 boost levels, without sacrificing mid-range boost delivery. This turbo represents the perfect synthesis of OE grade manufacturing processes and aftermarket performance improvement while maintaining factory fit. We feel this is the ultimate answer for the discerning performance enthusiast.

While this turbo is a bolt in component, it will require the addition of an external bypass valve (like the IPD Boostability components) for more stable boost control. IPD strongly recommends our Bosch 650cc injectors (121145) and proper tuning (like our friends at MTE) to protect your investment. We have complete kits available for the 2004-07 R models and we can help with components for other 1994-2009 turbo models as well.
