4T4 Turbocharger Base Plus Kit - Blue Silicone Includes Tune

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.

This kit contains the major components required to complete your Stage 3 project without having to fabricate components to support an external diverter valve. Larger turbochargers typically don’t come equipped with an integrated compressor bypass valve. Fabricating metal pipes and locating an external diverter valve can turn into a very expensive investment. Ipd designed upgraded components able to withstand the harshest environments that allowing you to bolt on an external diverter valve in the correct location supporting the upgraded 4T4 turbocharger. 

If you have previously upgraded the exhaust and downpipe on your car, this is the kit for you. These components will connect to exhaust that was designed for the K24 turbo, but we strongly recommend a high quality exhaust and catalytic package for best turbo response. This kit does not contain an intercooler. An intercooler upgrade is not required for this application but will certainly help with more consistent year round performance.
