Understanding the Foxbody’s Appeal
From its iconic lines to its aftermarket support, the Foxbody Mustang holds a special place in automotive history. It’s a prime canvas for modifications, and an LS engine swap is a natural evolution. Adding a turbocharger takes it to the next level.
The Power of LS and Turbocharging
The LS engine family offers robust construction and impressive power. Turbocharging harnesses exhaust energy to compress intake air, increasing horsepower and torque significantly. The LS and turbo combination is a winning one.
Key Components of a Winning Combination
Building the perfect Foxbody requires careful component selection.
Selecting the Perfect Forced Air Inducer
The turbocharger is the core. Choices include single and twin-turbo setups, depending on goals, driving style, and budget. Consider brands like Garrett and BorgWarner, along with the turbo’s size and A/R ratio.
Routing the Exhaust: Manifolds and Headers
Headers and manifolds direct exhaust gas. Choose stainless steel or mild steel based on budget and durability needs. Fitment in the Foxbody engine bay is key.
Regulating Boost: The Wastegate
The wastegate controls boost pressure by diverting excess exhaust. Select the appropriate size for your desired boost levels.
Managing Pressure: Blow-Off or Diverter Valves
BOVs and DVs release excess pressure. BOVs vent to atmosphere, while DVs recirculate the pressure. They protect the turbo.
Cooling the Charge: The Intercooler
Intercoolers cool the compressed air for denser intake. Air-to-air and air-to-water systems exist, with layout critical for the Foxbody.
Fueling the Beast: Upgrades
Fuel system upgrades are vital. Use larger injectors, a high-flow fuel pump, and upgraded lines to deliver the necessary fuel.
Orchestrating the Symphony: Engine Management
The ECU is the brain. A proper tune maximizes performance and reliability. Consider standalone ECUs or piggyback systems, along with dyno and street tuning.
Adding the Finishing Touches: Additional Components
Include oil lines, air filters, exhaust modifications, and gauges to complete the system.
Planning and Preparation: Laying the Groundwork
Before the wrenching begins, meticulous planning is required.
