Vargas Stage 1 Turbo Upgrade - F10 M5, F06/F13 M6

Important Note: these turbos will work on all models listed below with S63 or S63TU engines. However, we need to know your exact year and model when placing an order. Vargas will build your turbos for your specific application.

Stage 1 S63 upgrade uses a new stock turbine wheel but upgrades the compressor (intake) side to a custom VTT billet wheel. The compressor wheel and housing are all custom cast to Vargas specs but appear stock. The new compressor and turbine bolt onto the stock manifold for an easy install (new seals recommended). Keeping the stock turbine gives near-stock throttle response and lag response and works better under higher boost levels. The Stage 1 works great as a OEM replacement that does not have to work as hard to make power (producing less heat). Vargas rates this turbo up to 800whp.

Turning up the boost is easy but puts greater strain on the stock turbos and generates more heat while straining support systems to keep up. Going to a bigger turbo obviously can generate more boost but it's usually the heat that kills boost and performance, not a lack of size. The higher temperatures spread throughout the rest of the engine and accessories, further straining the oil and cooling systems (which are really undersized to begin with). It's also not good for the life of the turbo. Using a mild upgrade such as Stage 1 can handle increased boost with less effort and heat. Add a reflash to the ECU(s) to match the turbos and you can achieve big power gains with a safer and more reliable platform

A $1,000 core charge has been added to the price shown. This charge can be refunded upon the return of your rebuildable original turbos. You can avoid the core charge altogether by sending your original turbos in for the upgrade. We recommend new seals, gaskets, and oil lines, just like with the factory turbos. See kits below.

Available as unfinished, dark titanium, or black ceramic finish.

These turbos are built to order and depend on the availability of cores. Typical build time is 4-6 weeks.

Not for RHD models.

Vargas Turbocharger Technologies (VTT) is an in-depth leader in turbocharger service, maintenance, and performance. VTT has been servicing turbos in a wide range of applications since 1978 and specialize in rebuilds and parts that allow turbos to run more efficiently and reliably (and yes, make more power too). In addition to rebuild services, VTT designs and manufactures upgrades and accessories that help you get more power or make the entire turbo system more reliable. Horsepower ratings are used as a reference for each tuning stage. Turbos make up just a portion of your horsepower goals. Proper tuning and additional hardware is required to take full advantage of these turbos.
