Understanding the M133 Engine and the ESS Supercharger Upgrade

The Mercedes-Benz M133 engine, found in models like the CLA45 AMG, GLA45 AMG, and A45 AMG, is a 2.0-liter turbocharged four-cylinder that already delivers impressive power stock—around 355 horsepower in early versions and up to 375 in later production runs. However, enthusiast demand for even more performance has led to the development of aftermarket supercharging systems like the ESS (Eaton Supercharger Solutions) kit. The goal of a 600-horsepower build transforms this compact engine into a street-legal missile, but it requires a precise understanding of the costs involved before committing to the project.

This article provides a comprehensive cost breakdown of installing an ESS supercharger on your M133 to reach the 600-horsepower milestone. We will detail each expense category, from the core hardware to labor, tuning, supporting modifications, and ongoing maintenance. By the end, you’ll have a realistic budget range and know what to expect from this significant performance investment.

Initial Costs of the ESS Supercharger Kit

The heart of the upgrade is the ESS supercharger kit itself. Designed specifically for the M133, this kit replaces the stock turbocharger system with a positive-displacement supercharger to deliver consistent, low-end torque and high-rpm power. The kit typically includes the supercharger unit, intake plenum, intercooler, drive belt system, and necessary bracketry.

  • ESS Supercharger Kit (base): $6,500 – This includes the supercharger, brackets, belt, and intercooler core.
  • Optional Upgrades:
    • Upgraded intercooler brick (for hotter climates): +$500
    • High-flow intake system: +$300
    • Installation gasket kit and hardware: +$200
  • Total initial hardware cost range: $6,500 – $7,500

Some suppliers offer a "full kit" that includes piping, silicone hoses, and all fasteners; anticipate a premium of $1,000–$1,500 for these extras. For the most accurate pricing, visit the official ESS Superchargers website or contact authorized dealers like Eurocharged, which often provides bundled packages.

Labor Costs for Installation

Installing a supercharger on the M133 is not a weekend DIY job for most owners. The engine bay is tight, and the work requires removing many stock components (intake, turbo, exhaust manifold, cooling system parts). Professional labor rates vary by region and shop specialty.

  • Estimated labor hours: 12–18 hours (experienced AMG specialist)
  • Average hourly rate: $100–$150 per hour
  • Labor cost range: $1,200 – $2,700

If you have access to a well-equipped shop and mechanical experience, you can save on labor but risk improper installation. Most owners should plan for $1,500–$2,500 in labor. Some performance shops offer flat-rate installation packages; inquire with local tuners like Weistec Engineering or MBWorld forums for referrals.

Tuning and Calibration for 600 hp

A supercharger alone will not make 600 hp without proper engine management calibration. The M133’s ECU must be remapped to adjust fueling, ignition timing, boost levels, and temperature thresholds. Tuning is a critical cost that can make or break reliability.

  • Dyno tuning session (full day with wideband lambda): $500–$750
  • ECU remapping (software and license): $300–$600 (if using a flashable tool like ECUTEK or a custom file from a tuner)
  • Remote tuning (data logging, revisions): $400–$700
  • Total tuning cost range: $800 – $1,350

Do not skip this step. Poor calibration can lead to detonation, overheating, or engine failure within miles. Reputable tuners such as Eurocharged or RENNtech have proven M133 calibration experience. Also, budget for a boost controller or MAP sensor upgrade (around $200) if required by the kit.

Supporting Modifications Needed for 600 hp

The stock M133 fuel system, intake, and cooling are not designed for double the factory power. To reliably support 600 horsepower, plan for the following upgrades. Prices are estimates and can vary by brand.

Fuel System Upgrades

  • High-flow fuel injectors (750 cc–1000 cc): $600–$800
  • Upgraded low-pressure fuel pump (in-tank): $400–$600
  • High-pressure fuel pump (HPFP) upgrade (if needed): $1,200–$1,800

Cooling System Improvements

  • Larger front-mount intercooler or upgraded heat exchanger: $500–$1,000
  • Additional electric water pump for intercooler loop: $300–$500
  • High-performance radiator (optional but recommended for track use): $600–$900

Intake and Exhaust

  • High-flow intake system (cold air or open element): $300–$500
  • Free-flowing downpipe and exhaust (mandatory for 600 hp): $800–$1,500

Transmission and Drivetrain

  • Upgraded clutch pack or torque converter (if automatic): $1,000–$2,500
  • Stronger driveshaft or axles (highly recommended): $1,500–$2,500

Miscellaneous

  • Upgraded engine mounts (to handle torque): $300–$500
  • Wider tires and wheels (to put power down): $2,000–$4,000

All supporting modifications together can easily add $5,000–$12,000 to the total build. For a 600 hp target, the minimum supporting modifications (fuel, cooling, exhaust, injectors) will cost about $3,000–$4,000. This article originally estimated $1,500, which is optimistic; a realistic budget is $3,000–$5,000.

Hidden Costs and Maintenance Considerations

Ongoing expenses are often overlooked. A 600 hp M133 supercharged engine generates significantly more heat, stress, and wear. Plan for the following:

  • Increased oil change intervals: Use high-quality synthetic oil (e.g., 5W-60). Every 3,000–4,000 miles: $120–$150 per change.
  • Spark plugs (one heat range colder): $80–$120 every 15,000 miles.
  • Belt replacement (supercharger belt): $50–$100 every 30,000 miles.
  • Potential engine internal failure: Be prepared for a piston ring job or rod bearing replacement. Set aside $1,500–$3,000 annually for unforeseen repairs.
  • Clutch replacement (manual transmission): $1,500–$2,500 if launching hard.

These maintenance costs should be factored into the total cost of ownership. Without a reserve fund, even a short detour from reliability can be financially devastating.

Cost-Saving Tips Without Sacrificing Reliability

If the numbers seem high, consider these strategies to reduce upfront expenses:

  • Buy a used ESS kit: Check forums like MBWorld or the ESS enthusiast group. A used kit in good condition can save $1,000–$2,000.
  • DIY installation (if experienced): You can save $1,200–$2,500 in labor. However, factor in time and specialty tools (about $200–$400).
  • Bundle tuning with installation: Some shops offer a package price. Ask for a quote that includes labor, tuning, and supporting parts.
  • Source parts from reputable eBay or Amazon vendors: For intercoolers and piping, but never counterfeit fuel injectors or pump.
  • Consider a lower power target: 550 hp requires less expensive fuel system upgrades (stock injectors may suffice) and less aggressive cooling.

Performance Gains and Real-World Results

With a properly installed ESS supercharger and supporting mods, the M133 can achieve 600 hp at the crank (approximately 500–520 whp on a dynojet). Torque exceeds 500 lb-ft. Typical gains over a stock M133:

  • 0–60 mph: 3.2–3.5 seconds (vs. stock 4.0)
  • Quarter-mile: 11.2–11.5 seconds at 125 mph (vs. stock 12.8–13.0)
  • Power delivery: Immediate low-end torque, less lag than big turbo setups

These numbers are achievable with a good intercooler and sticky tires. Unsprung weight reduction (lighter wheels, carbon ceramic brakes) can further improve response. Many owners report daily-driver usability as long as boost is kept conservative.

Comparison with Turbo Upgrades for 600 hp

An alternative path to 600 hp is upgrading the stock turbo to a larger hybrid unit or a full GTX2860R or GTX3071R kit. Here’s a quick cost comparison:

  • Big turbo upgrade (turbo + downpipe + tune): $3,500–$5,000 (less initial cost than ESS)
  • Supporting mods needed: Similar fuel and cooling ($3,000–$5,000)
  • Labor: $1,000–$2,000 (turbo swap is easier than supercharger)
  • Performance: More top-end power but more lag; lack of low-end torque compared to positive-displacement supercharger.

The ESS supercharger is superior for street driving because it delivers torque from idle, but it costs $2,000–$3,000 more upfront. For track or drag racing, a big turbo may provide better top-end numbers at a lower price. Your choice depends on driving preferences.

Final Cost Summary Table

Here is a consolidated budget for a 600 hp ESS supercharged M133, including both low-end and high-end estimates:

Item Low Estimate High Estimate
ESS supercharger kit & components $6,500 $7,500
Labor for installation $1,200 $2,700
Tuning & calibration $800 $1,350
Fuel system upgrades $1,000 $3,200
Cooling system upgrades $800 $2,400
Intake & exhaust $1,100 $2,000
Transmission/drivetrain $1,000 $5,000
Maintenance reserve (annual) $1,500 $3,000
Total (build only, no reserve) $12,100 $24,150

Note: The original article estimated $11,300–$11,800, which omits transmission upgrades and detailed cooling/fuel systems. A realistic minimum for a reliable 600 hp build with all supporting modifications is around $14,000–$16,000 including labor and tuning. If you can do your own labor and source used parts, you might get closer to $10,000–$12,000.
