Collection: RB Collection

The RB26DETT is one of the most celebrated inline-six engines ever built — the twin-turbocharged heart of the Nissan Skyline GT-R that dominated motorsport and built the GT-R legend. J-Spec Garage's RB Collection covers the parts to build and sustain serious RB power, from the RB26DETT in the R32, R33, and R34 GT-R across the broader RB-series family.

Shop forged pistons and rods, head studs, camshafts, valvetrain, gaskets, oil system upgrades, and rebuild components from Brian Crower, Tomei, GSC Power Division, Platinum Racing Products, and more. Whether you're refreshing a stock RB or assembling a 1,000+ hp build, these are the components to do it reliably — backed by our price match guarantee and fast US shipping.
