Vargas Stage 1 N20 turbo upgrade is good up to 350whp with proper tuning and high grade fuel. Vargas N20 turbo is an all-new turbo specially made for Vargas. They build it with a billet compressor wheel of their own design and a stock turbine. It will accept all of the stock water and oil lines and the original diverter valve (upgraded DV is recommended). This kit is a direct bolt-on replacement for the original turbo and necessary if you want to start making big power from the N20.

The stock plastic diverter valve and chargepipe is the weakest point for boost leaks (the plastic cracks). Vargas Turbo recommends upgrading it to a stronger DV design. The aluminum DV designs will hold up to just about any boost level currently available.

Vargas Turbo Technologies has been in business since 1979, offering rebuilt and re-engineered turbo solutions. For the BMW market, they identified a need for both cost-effective turbo replacements and proven turbo upgrades. 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!

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: 350. 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 tuning is recommended to match thIS turbo to your existing mods and upgrades.

For the racing enthusiast or those just looking for the best, this is the ultimate upgrade to fully maximize the power output of your EWG N55 engine. The compressor wheel inside the turbocharger is increased in size allowing ~30% greater flow thus enabling additional boost pressures at higher engine speeds while retaining efficiency.These are fully cast turbos that are manufactured to Dinan specifications along with an upgraded thrust system over the stock turbo to ensure reliable and prolonged life. In order to attain maximum advertised power gains these big turbos will need to be paired with DINANTRONICS Stage 4, as well as Dinan’s intercooler to fully regulate the boost increase and deliver a polished product although the exhaust and intake are also recommended. 

Benefits of the Dinan Big Turbo for the EWG N55 Engine:

• Fully cast turbo that is manufactured to Dinan specifications with an upgraded thrust system thereby avoiding lengthy turnaround times caused by a core exchange program. 
•  Larger billet compressor/impeller wheel that allows ~30% greater flow over stock which then enables additional boost to be realized while retaining efficiency.
• Turbo assembly is compatible with electric wastegate vehicles only.
• Peak power: 445 HP @ 6000 RPM and 455 ft-lbs @ 3000 RPM and a max gain of 128 HP @ 6000 RPM and 113 ft-lbs @ 6000 RPM when coupled with other Dinan Performance upgrades. (Data from F22 M235i.) 448 HP @ 6500 RPM and 417 ft-lbs @ 3000 RPM and a max gain of 152 HP @ 6500 RPM and 123 ft-lbs @ 6500 RPM when coupled with other Dinan Performance upgrades.
