QT 3.8L VR38 Performance Long Block - Stage 0
The QT 3.8L VR38 Performance Long Block is engineered for enthusiasts and professionals who demand reliability at high power levels from their Nissan GT-R. Fully assembled and ready for installation, this long block is built with meticulous attention to detail using precision machining and carefully selected OEM components.
This is not a mass-assembled engine — it is a carefully engineered foundation designed to survive and perform under serious power, load, and abuse.
Every QT engine is thoroughly inspected, measured, and refined to ensure optimal tolerances, smooth operation, and long-term durability under increased power and torque. The rotating assembly is balanced to ensure stability at high RPM and under extreme load, critical clearances are verified, and all components undergo a multi-stage cleaning process before final assembly.
With a focus on strength, consistency, and real-world performance, QT applies proven motorsport principles and hands-on engine-building expertise to the VR38 platform. The result is a solid foundation capable of supporting demanding street, track, and high-horsepower applications—without compromise.
This long block is designed as a rock-solid base for high-horsepower GT-R builds, combining OEM reliability with performance-focused preparation — built by people who genuinely understand how this engine must be done right.
