This RWD Converted Turbo LS Swap Impala SS is a Super Sleeper! (He Explains How He Did It w/Pics!)

What happens here

After completing all mechanical and electrical modifications, perform initial testing, such as starting the engine and driving the car. The owner notes that the suspension was 'just set' and not finely tuned, but the car still achieved a 9.8681-second quarter-mile pass at 140.67 mph with only 17 pounds of boost, indicating significant untapped potential. Fine-tune engine parameters (boost levels, timing, fuel delivery) and suspension settings to maximize performance and consistency. The ultimate goal is to optimize the car for Drag Week and achieve even faster times.

Goal: Achieve optimal performance and consistency on the drag strip through tuning and adjustments.

Tools and materials

  • Dynamometer — Measuring engine power output and aiding in tuning
  • Time Slip N/A — Documenting drag strip performance
  • Tuning Software/Laptop — Adjusting engine parameters (fuel, timing, boost)
  • Wideband O2 Sensor — Monitoring air-fuel ratios during tuning
