Genuine Nissan RB26DETT 2.6L inline-6 twin-turbo Engine

The Nissan RB26DETT is a 2.6-liter, twin-turbocharged inline-6 engine, purpose-built for the legendary Skyline GT-R. Featuring a factory-balanced forged steel crankshaft, individual throttle bodies (ITBs), and a dedicated oiling system, this engine is revered for its high-RPM power delivery and ability to reliably exceed 600-800+ horsepower with proper tuning.

  • Engine Code: RB26DETT

  • Configuration: Inline-6 (Straight 6)

  • Displacement: 2,568 cc (2.6L)

  • Bore x Stroke: 86 mm x 73.7 mm (Undersquare / High-RPM design)

  • Compression Ratio: 8.5:1

  • Induction: Sequential Twin-Turbo (Ceramic or Steel wheel depending on revision) – T28-style turbochargers (Garrett/IHI)

  • Fuel System: Multi-Point Electronic Fuel Injection (MPFI)

  • Valvetrain: DOHC (Dual Overhead Camshaft), 4 valves per cylinder, Belt drive

  • Oil Capacity: 5.0 Liters (with filter)

  • Engine Weight (Dry): Approx. 255 kg (562 lbs)

  • OEM Horsepower: 280 PS (276 hp) @ 6,800 rpm (Gentleman's Agreement) / Actual ~320-330 hp

  • OEM Torque: 368 N·m (271 lb·ft) @ 4,400 rpm

  • Redline: 8,000 rpm (Factory)

  • Factory Forged Steel Crankshaft & Connecting Rods: Enables safe high-horsepower builds (600-800+ whp) without replacing the bottom end.

  • Individual Throttle Bodies (ITBs): Six separate throttle plates (S1/S2) provide instant throttle response and distinctive intake sound.

  • Closed-Deck Cast Iron Block (Revised): Offers superior cylinder rigidity for high boost applications (common upgrade to "N1" spec block for extreme builds).

  • Piston Oil Squirters: Directs oil to piston skirts and cylinder walls for enhanced cooling and detonation prevention.

  • Separate Oil Pan Baffle Plate: Prevents oil starvation during high-G cornering (track/drift use).

  • Twin T25/T28 Turbochargers: Sequential setup (ceramic wheels on early models, steel on late R34 N1 spec) minimizes lag while providing strong mid-range power.

  • DOHC 24-Valve Cylinder Head: High-flow ports designed for naturally aspirated-like response with forced induction.

  • Front-Facing Intake Plenum: Allows for easier front-mount intercooler piping vs. the RB20/25 series.

  • Nissan Skyline GT-R R32 (1989-1994) – Direct fit

  • Nissan Skyline GT-R R33 (1995-1998) – Direct fit (Note: Minor oil pan/pickup differences)

  • Nissan Skyline GT-R R34 (1999-2002) – Direct fit (Includes VVTi – verify year)

  • 1x Intake Plenum with 6 Individual Throttle Bodies

  • 2x Exhaust Manifolds with Turbochargers (Twin T25/T28 – ceramic or steel depending on revision)

  • Ignition coils (individual pencil coils), alternator, starter, and oil filter relocation kit.
