Vargas Stage 1 Turbo Upgrade - E9X 335i N54

Stage 1 N54 upgrade keeps the stock turbine wheel but upgrades the compressor (intake) side to a billet TD04 14T wheel. The 14T wheel, compressor housing, and bearing housings have all been machined and optimized to work with the stock turbine wheel. This 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. Vargas rates this turbo up to 525whp (over 600hp!).

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 greater 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.

Included:
> TD04 14T billet compressor wheel
> Vargas upgraded wastegate arm and bushing
The Vargas rattle kit has much tighter clearances than the originals. The kit uses stainless steel bushings pressed into the housing, new flapper assemblies, wastegate arms, rod ends, and stainless steel c-clips. Flapper is upgraded to 12.6mm (1/2").
> 30% larger thrust bearing
Larger thrust bearing has longer bearing life thanks to more surface area. With the larger TD04 bearing one more problem area of the N54 turbos is virtually eliminated.

Options:
+ Billet 6x6 compressor wheel (now standard)
+ 2000° ceramic coating
+ Inlet & Outlet bundle at a discount - make sure the rest of your intake and intercooler are up to the task of more boost!

No core charge with the new turbo option! Rebuilt turbos include a core charge (used cores must be returned within 30 days).

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.

Are you reusing your original oil supply/return lines?
In some cases, the turbocharger oil lines can be reused. Careful inspection is highly recommended. Aging oil lines are a common source of leaks. The oil supply and return lines can also become kinked during the turbocharger removal process. If you suspect that your lines have been bent or damaged, it is wise to replace them preventively. Another reason to replace the N54 oil lines is that the lines can become plugged and restricted by burnt oil residue, causing the turbochargers to overheat and fail. If you're replacing your turbos, we recommend replacing the oil supply/return lines while you're in there. See below for BimmerWorld Recommended Related Items.
