Top 10 B58 Turbo Upgrades
From sneaky stock-location cast turbos to massive top-mount watermelons. This is how you breathe fire.
1. KLM Race Savage Series (PTE 7680 Next Gen)
The absolute pinnacle of B58 performance. This massive twin-scroll top-mount kit features the 1400+ HP capable Precision 7680. It’s a dragstrip missile setup that requires a fully built engine, built trans, and heavy fueling mods to spool.
2. DOCRace Top Mount (PTE 7275 Next Gen)
The legendary 1200+ HP setup. DOCRace’s tubular manifold paired with a PTE 7275 is responsible for some of the fastest B58 timeslips in the world. Significant lag for the street, but when boost hits, the violence is unmatched.
3. KLM Race Bottom Mount (PTE 6870)
For those who want 1000+ WHP but prefer a stealthier bottom-mount layout. The 6870 is a phenomenal mid-to-large frame turbo offering a better powerband for the street than the 7275 while still cracking four-digit horsepower.
4. SpeedTech Top Mount (BorgWarner EFR 8474)
A beautifully crafted top-mount kit utilizing BorgWarner’s EFR series. Known for incredible transient response thanks to the Gamma-Ti turbine wheel, making it an elite choice for responsive 900+ HP setups.
5. BigBoost Stage 3.4 Bottom Mount
BigBoost uses massive Garrett cores in a bottom-mount configuration. The 3.4 kit is capable of 900+ WHP and is a favorite for guys who want extreme power without fabricating top-mount exhaust routing.
6. Dynamic Autowerx (DAW) Ultra Flow 4
One of the largest hybrid/cast upgrades available. Squeezing every last drop out of the stock location, this beast flows enough to hit 850-900WHP on E85 without the complexity of an external wastegate tubular kit.
7. Pure Turbos Pure800
The gold standard for a 700-800WHP daily driver. Drops right into the factory location, spools incredibly fast, and has proven reliability. The most popular B58 cast turbo upgrade for a reason.
8. Vargas VTT GC (Game Changer)
A solid, budget-friendly cast upgrade. Perfect for the 600-700WHP range. It keeps the factory heat shields and looks entirely stock to the untrained eye or the feds, making it a great sleeper setup.
9. TurboSystems Stage 1
A mild upgrade over the stock turbo. It utilizes an upgraded billet compressor wheel in the factory housing. Good for around 550WHP, giving you a noticeable bump in top-end pull over stock without any extra lag.
10. Pure Turbos Pure600
The entry-level "писюлька" upgrade. Barely larger than stock, designed to hold boost better towards redline where the factory turbo falls flat. Ideal if you just want a reliable 500WHP daily on pump gas.
