BMW S63 W.4 Turbocharger Upgrade
The BMW S63 W.4 Turbochargers are complete, bolt-on replacements for the stock turbochargers. There are no core charges with these turbos. No need to send in your stock turbos to get modified while your car sits in pieces waiting for the turbos to get back. Simply install the Weistec W.4 Turbochargers when you receive them. All necessary hardware is included. New turbo inlet pipes that mate up to the factory airboxes(or any bolt-on aftermarket intake), and new charge pipes with integrated methanol injection ports that connect the turbos to the factory intercoolers come standard with the S63 W.4 Turbochargers. A pair of Weistec 304SS downpipes are also included to connect the turbos to the rest of the exhaust without any cutting or welding as downpipes that are for the stock turbos will no longer fit the vehicle. Stainless braided oil and coolant lines are included with custom CNC machined and anodized fittings. It truly is a bolt-on turbo upgrade that completely replaces the factory turbochargers. Even the factory engine cover still fits over the turbos.
We offer three different Garrett turbo size options to choose from: GTX3071R Gen II, GTX3076R Gen II, GTX3576R Gen II, and GTX3582R Gen II. This gives choices that range from reasonable response and mid-range to all-out monster top-end power!
In addition to turbo size options, we also offer a Water/Methanol Injection System and Weistec Anti Surge Valves as upgrades to the W.4 Turbochargers. Couple all these upgrades with a custom tune and you have the recipe for serious power.
An Engineered Solution
The goal of the W.4 Turbocharger Upgrade was to offer bolt-on full replacment turbochargers that fit with out the need for any custom fabrication or permanent modification to the engine or chassis. Something that will let you take your M5/M6 to unreal power levels. The W.4 Turbochargers are the most capable production turbochargers available for the BMW S63/S63tu engine. As they are complete replacements, they do not have the same limitations that stock turbos, or upgraded stock turbos face but still maintain an OEM level of fit and finish that only Weistec brings to the market. This isn't a pair of universal turbos fitted to the car with a lot of cutting and welding. Its an upgrade that can be installed in a day's worth of work with typical mechanic's tools.
