The Bosphorus Innovations Stage 1.5+ Turbo Water/Methanol Injection Kit is the ultimate all-in-one system for turbocharged vehicles. Combining a digital boost gauge, progressive water-methanol controller, fail-safe system, and a fast-reacting safety solenoid valve, it features a built-in 10 bar (145 psi) MAP sensor and a striking white/red dual-tone LCD screen for precise tuning and absolute safety.
Integrated 10 Bar MAP Sensor & Dual-Tone LCD: Built-in absolute pressure sensor paired with a high-visibility screen to monitor boost, injection status, fault codes, and custom parameters.
Solenoid Valve Safety Protection: Fast-reacting integrated solenoid locks fluid in place when idle—making it 100% safe for rear-mounted tanks, vacuum zones, or lower nozzle mountings.
Pulsation-Free High-Pressure Pump: Utilizes an internal bypass architecture instead of a pressure switch for a smooth, constant, and even spray pattern.
Generous 5.9L Fluid Reservoir: Includes a large 5.9-liter plastic tank to guarantee a reliable supply during intense performance driving.
Bosphorus Innovations Stage 1.5+ Turbo Water/Methanol Injection Kit (MAP, LCD & Solenoid)
Engineered for extreme performance builds, the Stage 1.5+ Turbo Water/Methanol Injection Controller merges multiple standalone instruments into a single, compact, high-precision unit. By introducing a fine water-methanol mist into the intake stream under boost, the system dramatically reduces intake manifold temperatures and exhaust gas temperatures (EGT) to prevent piston melting while eliminating engine knock through increased effective octane ratings.
Advanced Solenoid & Controller Architecture Unlike standard setups, the Stage 1.5+ Turbo kit includes a fast-reacting solenoid valve mounted directly before the nozzle. This eliminates any risk of gravity siphoning or unwanted fluid leakages in complex routing configurations. Furthermore, the advanced digital gauge controller lets you tailor your injection curve with unmatched precision, supported by 100% methanol-resistant nickel-plated brass, standard brass, and EPDM-grade plastic components.
