Turbos

If more boost and reliability are your goals choose from one of our BMW turbo upgrades. Our turbo upgrades range from stock turbos rebuilt with stronger internals to all-new, ground-up turbo upgrades. BMW turbos such as the N54 are capable of really impressive power numbers on stock engine internals but the factory turbos lack the precise tolerances and reliability that an upgraded unit will deliver. In other words, the stock turbos can only do so much and if big power (>400whp) is your goal a turbo upgrade must be in your plans. Our partners are leading experts in turbo technology and upgrades. Each Stage has been professionally developed and tested. Additional upgrades and tuning may be, or is, required. Contact us for more details on tuning options.

This is an OEM replacement left side (bank 2) turbo assembly for the S63 engine. This is a new turbo from Garrett, not a rebuilt unit. This is a complete assembly, including the manifold to the engine and the wastegate. Signs of a failing turbo are high oil consumption and blue smoke from the exhaust (not from a leak or failing CCV system) because the internal oil seals are no longer retaining oil. Without critical lubrication and cooling effects from oil, the turbo shafts and bearings are usually the first to wear and that requires a complete rebuild. You might also see increased turbo lag or failure to hold boost, which is usually a sign of a failing wastegate or some other internal issue. With any internal problems, the turbos need to be replaced. This is a new turbo - No core charge.

Vargas Stage 1 N54 turbochargers are brand new and include all housing, wheels, and internals. These are brand new units and thus do not require a core charge, making the process easier and simpler. All VTT turbos come with a performance TD04 upgraded thrust to extend the life of the turbochargers. The stock thrust system has shown to be prone to failure and upgraded thrust parts were created to remedy this. The upgraded thrust option consists of an upgraded thrust bearing and a 30% increase in surface area on all complimenting thrust pieces. Every VTT Stage 1 upgrade includes a Billet VTT Compressor wheel. These are fully forged billet wheels, utilizing the ultra-efficient 6×6 blade HTA wheel design as well as extended tip technology to increase airflow a solid 20% over the cast 14T wheels. The use of an aluminum aftermarket charge pipe, and BOV combo is always recommended with upgraded turbos. Add the VTT Cold side Charge pipe, and Turbosmart Raceport BOV to your order for just $349! Please see our BOV article for proper installation to avoid compressor surge! Upgrading your PCV valve is always recommended at the time of turbo upgrade or replacement, as the stock valve can be worn. This means it can stop functioning to its full potential, causing oiling issues with your BMW. This upgraded valve not only replaces the worn stock valve it is also much stronger and will help eliminate any future PCV issues.

Vargas Stage 1 N55 turbo upgrade is good up to 425whp with proper tuning and high grade fuel. Vargas N55 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 N55.

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: 425. 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. (Data from F32 435i. Other variants may differ.) 
  •  Dinan Installation instructions detail a procedure which is quicker than BMW's turbo replacement procedure saving the end-user money and time at the shop (Applicable to RWD vehicles only). 
  • Includes o-rings and gaskets needed for complete installation on a RWD vehicle only. If installing on an xDrive vehicle Dinan P/N D313-0117 is required for additional installation hardware.
  •  Factory matching new car warranty (4yr/50k) when run in Dinan specification.
  • 50 State Emissions legal; CARB EO # D-176-49.

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.

Ready to take your B58 to the next level? Don't want to deal with core charges, long lead times, or restrictive factory housings? Look no further! VTT has you covered with our 100% new casting B58 “GC” turbocharger upgrade. We start by keeping the great design elements of the factory B58 turbo and removing the not-so-great ones such as the small factory inlet area, bearing housing oil structure, thrust bearing, and anything else we saw that could be improved upon. With the basics covered, we stepped it up a level adding in proprietary VTT changes and finished off by having all these parts cast to OE quality. What this means for you is serious B58 power made easy; GC's are a drop in B58 turbocharger upgrade that supports over 600WHP while maintaining factory spool and all factory connections including oil, water, downpipe, and charge pipe. Key Design Elements: All new castings with factory restrictions removed. No oversized wheels stuffed into factory housings here! GC is cold side, and bearing housing only Full 3' turbocharger inlet size with an included 3-4' silicone inlet elbow that removes ALL factory inlet restrictions 9-blade Mar-M 246 turbine wheel with the latest aero technology for increased flow while maximizing spool 9 blade “point-milled” compressor wheels with the latest aero technology to maximize flow while virtually eliminating surge Direct connection to ALL factory lines including oil, water, downpipe, and factory charge pipe Redesigned, and improved internal components including bearing housing oiling, and an upgraded thrust bearing NO CORE CHARGES. The new unit is sold to you outright. Keep your old unit in case you ever want to go back to stock. Or sell it to recoup your investment -it’s up to you! No long lead times; once fully released production units will be on the shelf for same to next-day shipping (please inquire about stock levels when ordering) Full 12-month unlimited mileage/No Hassle Warranty. If you have an issue we will replace the unit no questions asked Turbocharger Purchase includes: 1 – VTT B58 “GC” turbocharger 1 – VTT B58 “GC” 3'-4' Silicone inlet elbow with adapters for factory connections 1 – 3' hose clamp for silicone inlet elbow As with any turbocharger upgrade it should be coupled with complimenting upgrades such as fuel system upgrades, intake, downpipe, intercooler, tune, etc. While you will see gains going from stock turbo to a GC/GC+ with no other changes, to realize the full potential of the upgrade other parts/tune must be added. The GC, GC-MID, and GC+ Come with a silicone intake tube, that will fit the stock airbox, and SOME intakes with no mods. It does not fit all, such as Injen, etc. If this is the case, you can either modify something work, or you can add the VTT MAF housing, and filter which will work with the GC inlet hose. Please be aware. This system removes the PTC heater, and it WILL register a shadow code in the DME. In our testing, this did NOT throw a check engine light. The code is only there if your scan the car. If you wish to remove the code it must be coded out.
