4T4 Turbocharger

If you drive a 2004-2007 R model, you’re a part of an elite group of Volvo enthusiasts. The R model is one of the most advanced performance vehicles, even compared to models offered today. The stock K24 turbocharger offered on the R can leave a lot to be desired when it comes to overall performance delivery. We’ve been testing and tuning the limitation of the R model since it became available in the U.S. market. Working closely with our tuning partner MTE has allowed us to discover the primary performance limitations.  

IPD’s 4T4 ball bearing turbocharger for Volvo’s B52X4T engines is the first completely custom manufactured bolt on turbo available. This is a serious turbo for the enthusiast that wants to extract the maximum performance from the factory supplied engine in their car or for the engine build producing up to 500 crank horsepower.

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.

IPD’s 4T4 turbocharger and associated components are designed to function in harmony as a kit and have been developed as such. Due to the complexity involved and nature of this product IPD cannot extend any warranty beyond basic 1-year manufacturing and workmanship defects when not used in conjunction with IPD 650cc fuel injectors, IPD bypass valve and IPD/MTC ECU tune. If you choose to install and use IPD’s 4T4 turbocharger with components and/or ECU tune not recommended by IPD, warranty claims will be subject to evaluation, failure due to improper tuning will not be covered.
