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.

No one buys an M3 because they like limits.

The Active Autowerke supercharger systrem is truly modular and fully upgradeable. Running on 91-93 octane pump fuel with full emissions system intact, this system has stood the test of real world conditions and delivers thrill-worthy performance on demand while still retaining that BMW feel for a comfortable daily commute.

VTT is proud to offer its very own N54 to B58 Coil conversion kit for the N54 platform. While factory coil upgrades such as S55, and our own N54 coil upgrades do provide more spark, the BMW B58 ignition coils are extremely robust and can support well over 1000whp with no issues. This means a plug, and play affordable solution that fits like stock, and looks AMAZING doing so! Vargas's 6061-T6 Billet bracket comes in a variety of colors including matching shades for every N54 Valve Cover we offer (even the cast wrinkle). This means you can mix and match the color of the bracket with coil color, with VC color to truly tailor your engine bay to look exactly how you want it to! The kit comes with the following: 1 – Billet Aluminum Coil Bracket in the color of choice or Genuine Carbon Fiber 6 – Plug and play VTT wiring harnesses 6 – Custom VTT stalks to convert the B58 coils to the N54 head (We ensure proper spring length inside the boot for optimal spring to plug contact) 6 – Coils in the color of choice (optional) **Note: This only fits the stock N54 Valve covers or Vargas Billet and Cast Valve Covers.

These extra-strength silicone pipes replace the plastic pipes coming from the turbos to the top-mount intercooler on the M3/M4. Since the stock pipes are plastic there is the potential for cracks and boost leaks which will surely spoil the fun.
