Top Performance Upgrades for the Nissan Skyline R34 GT-R
The Nissan Skyline R34 GT-R is one of the most celebrated performance cars ever built. With the legendary RB26DETT twin-turbo inline-six under the hood and the advanced ATTESA E-TS all-wheel drive system, the R34 GT-R earned its reputation on both the street and the track. At I Love To Boost, we carry a deep catalog of R34 GT-R performance parts to help you build yours to its full potential.
Turbo and Forced Induction Upgrades
The factory twin-turbo setup on the RB26DETT is a solid foundation, but upgraded turbos unlock serious power. Single turbo conversions remain the most popular route for big horsepower, with kits from brands like HKS, GReddy, and Garrett offering everything from 500 to 1000+ horsepower potential. Upgraded intercoolers, wastegates, and blow-off valves round out the forced induction package. Browse our full turbo and forced induction catalog.
Fuel System
More boost means more fuel. Upgraded injectors (typically 740cc to 1000cc+), high-flow fuel pumps, adjustable fuel pressure regulators, and larger fuel rails are essential for any R34 build pushing beyond stock power levels. Our fuel system collection covers everything from drop-in upgrades to full competition fuel setups.
Suspension and Handling
Putting power down effectively requires proper suspension. Adjustable coilover kits from brands like HKS, Tein, BC Racing, and Ohlins let you dial in ride height and damping for your specific use case — whether that is spirited street driving, circuit time attack, or drag launches. Upgraded sway bars, tension rods, and control arms further sharpen the R34's handling. See our suspension and coilovers collection.
Brakes
With more power comes the need for more stopping force. The R34 GT-R's Brembo brakes are capable in stock form, but track use and high-horsepower builds demand upgraded rotors, performance pads, stainless brake lines, and big brake kit options. Check our brake upgrades catalog.
ECU Tuning and Electronics
Getting the most from your R34 GT-R build requires proper engine management. Standalone ECUs like the HaltechLink or Motec give full control over fuel, ignition, and boost. For less intensive builds, piggyback controllers and boost controllers provide meaningful gains without replacing the factory ECU entirely. Wideband O2 gauges, EGT sensors, and data logging round out the electronics package. Browse ECU and electronics.
Engine Internals
For builds targeting 600+ horsepower, the RB26DETT benefits from forged pistons, upgraded connecting rods, a stroker crankshaft, and metal head gaskets. Upgraded camshafts and valve springs allow higher RPM operation, while ported cylinder heads maximize airflow. Our engine and intake collection covers these components.
Drivetrain
High-power R34 GT-R builds quickly exceed the limits of the factory clutch and transmission. Upgraded twin-plate and triple-plate clutch kits, reinforced transfer cases, and upgraded axles keep everything connected under hard launches. Explore our drivetrain and clutch components.
