Nismo R34 GT-R 400R: The 1999 Limited Edition

The Nismo R34 GT-R 400R (released in 1999) is one of the rarest and most powerful R34 variants ever produced. Built by Nismo as a limited-edition demonstration of what their tuning could achieve on the brand-new R34 platform, only a handful were produced before Nissan launched their own factory R34 V-Spec II program. The 400R was Nismo's statement that the R34 could go beyond the gentleman's agreement 280 PS and deliver true performance to wealthy collectors.

The Build

The Nismo R34 400R included:

• Engine: Heavily modified RB26DETT
• Output: 400 PS catalog (the "400R" name)
• Internals: Forged pistons, billet rods, upgraded valvetrain
• Turbos: Larger HKS or Garrett units
• Body: Nismo aerodynamic package with carbon fiber components
• Suspension: Nismo-tuned coilovers
• Brakes: Larger calipers and rotors
• Wheels: Lightweight forged 18-inch
• Interior: Custom Recaro seats and instrument modifications

Production Numbers

The Nismo R34 400R was extremely limited — fewer than 50 units total. Each was built individually at the Nismo facility in Japan, with each customer specifying minor variations. The total production number is disputed but most sources cite under 50.

Today's Market

When Nismo R34 400Rs come to market, prices are stratospheric:

• Confirmed authentic examples: $1+ million
• Concours-condition: $1.5-2 million
• Provenance with original Nismo documentation: Premium pricing

The 400R is one of the most valuable R34 variants ever sold.

Legacy

The Nismo R34 400R is a forgotten gem of JDM history. Most enthusiasts know about the Nismo Z-Tune (the famous 20-unit special) but the 400R came first and established the template for what Nismo could achieve when given freedom to push the R34 platform.

For Nismo collectors and R34 historians, the 400R is essential. It's the bridge between the production R34 GT-R and the eventual Z-Tune masterpiece.
