Product Description:

The Blouch Dominator 1.5XT-R is a refined evolution of the popular Dom 2.5XT-R, designed for faster spool and improved drivability. Originally developed for 2.0L applications in the UK, this turbo features a custom 56.5mm turbine wheel in place of the 60mm turbine found in the Dom 2.5XT-R. The result? Quicker spool response with a slight trade-off in high RPM power, making it an excellent choice for those seeking a balance of power and responsiveness.

Beyond the turbine, the Dom 1.5XT-R incorporates cutting-edge turbo technology from Blouch Performance Turbo, including:

• Billet, fully-machined closed die forged XT-R compressor wheel with advanced aerodynamics for optimal efficiency.
• Custom compressor housing, precision-machined in-house for improved fitment.
• Water-cooled center housing featuring a low-inertia, low-friction ceramic ball bearing assembly for enhanced durability and performance.
• Blouch custom turbine housing (10cm²) with an adjustable upgrade actuator, ensuring precise boost control.

Designed to eliminate boost creep issues, the turbo’s wastegate actuator and turbine housing work in harmony to provide a flat, consistent boost curve, making tuning easier.
