Stage 1 N55 upgrade uses a new stock turbine wheel but upgrades the compressor (intake) side to a custom VTT reverse 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 425whp. This part number is only for cars with the electronic wastegate (generally cars built from 7/2013). Not for RHD models.

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.

No core charge as this is a new turbo! We recommend new seals and gaskets for the oil lines, coolant lines, and charge pipe ducts. See kits below.

Available only as a stock-like grey finish.

Turbos are built to order and can take between 1-3 weeks for processing and shipment.

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.
