For those seeking a top-tier OE replacement upgrade turbo for their 1.6L car, the BorgWarner unit is the ultimate solution. It seamlessly replaces vehicles originally equipped with MINI Factory Borg Warner Turbochargers, offering an upgraded alternative for both the Cooper S and JCW models.

Keep in mind that the larger inlet necessitates an aftermarket intake system featuring a silicone hose or an aftermarket silicone intake hose to adapt to the larger inlet. Adjustments to factory inlet boots may be required for proper fitting.

With a piggyback tune, this turbo delivers power ranging from 225 to 255HP. With a more aggressive tune, you can push the limits up to 300HP. However, it's crucial to acquire a custom flash tune (not supplied) to prevent the turbo from backing off during full pulls.

Warranty claims for this turbo upgrade must be supported by a receipt from a professional repair facility, indicating the installation date and vehicle mileage. Additionally, a separate receipt from a professional repair facility should accompany the warranty claim, specifying the date and mileage of the turbocharger failure, reasons for the failure, and proposed repair solutions if necessary. Borg Warner will consider replacing a failed turbocharger due to material and workmanship defects, provided proper documentation is provided. Please note that all associated labor charges for diagnosis and repair are the responsibility of the vehicle owner.

• Also referred to as a Lambda Probe.

Vargas builds on their stock replacement turbo kits with this Stage 1 upgrade. Using the stock housings but with improved internals, this N54 turbo upgrade is good up to 470whp. Stage 1 is a hybrid of stock and upgraded internals - a new larger higher-flow cast compressor wheel matched with the stock turbine wheel. The Vargas stainless wastegate arms are also part of the rebuild. The Vargas standard rebuild is good up to 400whp so Stage 1 gives you a more capable turbo system to match your upgrade goals.

Vargas Turbo Technologies has been in business since 1979, offering rebuilt and re-engineered turbo solutions. With the N54, they identified a need for both cost-effective turbo replacements and proven turbo upgrades. The biggest complaint on N54 turbos is the rattle from the wastegates. The factory wastegates have actuator arms that lose their tension very easily, resulting in an annoying rattle. N54 wastegate rattle is the biggest complaint we hear from our customers. Vargas rebuilds each turbo assembly with OEM internals and replaces the actuator arm with a stainless steel arm of their own design. Because the Stage 1 uses stock BMW/Mitsubishi turbo housings, all of the stock turbo plumbing and intake hoses will match up. It's recommended that the rest of the system be upgraded to handle your tuning goals. The final Vargas rebuilt turbos are better than the factory rebuilds and at a lower cost!

Two other upgrades are also offered for Stage 1 -

• TD04 thrust bearing upgrade - stronger and 30% more surface area than the stock thrust bearing for better bearing life and less stress
• Billet Aluminum compressor wheel - stronger and more efficient compressor wheel than stock for 20% better airflow

Silicone inlet and turbo manifold pipes are also strongly recommended as upgrades over the stock plastic and aluminum pipes. Since both are prone to cracks, the silicone will be a lot stronger and almost no chance of a disappointing boost leak. Turbo replacement is the best time to add the silicone hoses. There are two styles of turbo inlet pipes - with stock diverter valves (DV) or with aftermarket blow-off valve (BOV). For the turbo manifold, there is no standardized connection to the intercooler so you will need to make note of which type you have and select the appropriate adapter from the options list.
Option A (+$25) - 2.5" and 90* turn up from the intercooler (CPE, AA, ER Sport, CXRacing)
Option B - 2.5" and angled up from the intercooler (AD Engineering, ETS, Helix, Cobb, ER Compeition)
Option C (+$25) - 3.0" and angled up from the intercooler (VRSF)
Option D (+$25) - 2.75" and angled up from the intercooler (Wagner EVO)
Option E (+$50) - 3.0" and straight out from the intercooler (AA Race)
Option F (+$25) - 2.5" and straight out from the intercooler (Forge)
Option G (+$15) - 3.0" and straight up from the interooler (AMS)

Install Kit - an Install Kit is also offered that includes all of the additional parts and pieces that will need to be replaced during this install (gaskets, hardware, etc).

Oil Recommendation - modern engine oil is formulated for emissions and to be environmentally friendly. The additives in current oil lowers the oil's ability to withstand high temperatures and stresses, lowering its shear strength and its lubricating properties. Vargas recommends oils with high ZDDP (zinc and phosphorus) content that will better protect and cool the turbo bearings. Examples of high-zinc oils are Red Line Race, Red Line Euro, Motul 300V Racing, Joe Gibbs Racing, Valvoline VR-1 oil, and most Diesel-spec oils that you can buy off-the-shelf. Some oils, especially the Race type, will need more frequent oil changes and may be harmful to catalytic converters.

WHP rating: 470. This rating is used to compare various stage of Vargas turbo kits. There is no advertised horsepower gain with this kit as it depends on your other mods and tuning. The rating is provided as a reference to use in your tuning planning. Custom N54 tuning is recommended to match these turbos to your existing mods and upgrades.
