Nismo 400R: The R34 Predecessor You've Never Heard Of

The Nismo 400R — not to be confused with the later R34 GT-R — was actually built on the R33 GT-R platform (1996-1998). It's the R33 variant that Nismo built with a 2.8L stroker RB26 and 400 PS catalog rating. Only 44 were ever built, making it one of the rarest production cars ever produced under the Nissan brand. The 400R is what happens when Nismo is given the freedom to build the ultimate R33 — and it's also the direct predecessor concept to the later R34 Z-Tune.

The Nismo Project

In 1995, Nismo approached Nissan about building a limited-edition R33 GT-R variant. The goal was to demonstrate what the RB26 platform could achieve when given full Nismo development treatment. Nissan approved the project, and Nismo began developing what would become the 400R.

The project was aimed at the highest-end Japanese buyers — customers who wanted something beyond even the R33 GT-R V-Spec N1. The target price was ¥12,000,000 — three times the standard R33 GT-R's price.

The 2.8L Stroker Engine

The heart of the 400R was a modified RB26DETT:

• Displacement: 2.8L (stroked from 2.6L) using HKS stroker kit components
• Output: 400 PS catalog (the "400R" name referenced this rating)
• Actual output: 450+ hp
• Block: Nismo-reinforced RB26 with additional oil cooling
• Internals: Forged pistons, HKS crankshaft, upgraded rods
• Turbos: Larger sequential twin turbos
• ECU: Nismo-tuned

The engine was assembled by HKS and Nismo working together. Each engine was hand-built and dynoed before installation.

Chassis and Aero

The 400R also received significant chassis updates:

• Suspension: Nismo-specific coilovers
• Brakes: Larger rotors and calipers
• Wheels: Lightweight forged 18-inch
• Aero kit: Dedicated front splitter, rear wing, side skirts, and rear diffuser
• Weight reduction: Approximately 80 kg lighter than standard R33

Production: Only 44 Ever Built

Nismo originally planned to build 100 units, but production was capped at 44 due to:

• Cost: Each car was extraordinarily expensive to build
• Engineering time: Nismo had limited engineering bandwidth
• Demand: At ¥12 million, the market was niche

Of the 44:

• 44 were sold to customers (all in Japan)
• 0 were retained by Nismo (they built the Z-Tune as their museum piece)

The Nürburgring Connection

The 400R was tested at the Nürburgring Nordschleife by Nismo's test drivers. Reported lap times were in the 7:52 range — extremely fast for a production car of 1996 vintage. This was faster than the standard R33 GT-R V-Spec's 7:59 time, demonstrating the improvement the 400R brought.

Today's Market

The 400R is one of the most valuable JDM cars in existence:

• Clean examples: $500,000-$800,000
• Mint low-mileage examples: $800,000-$1,200,000
• Concours-condition examples: $1+ million

A 400R sold at BH Auction in 2021 for ¥86,250,000 (approximately $780,000 at that time's exchange rate).

Legacy

The Nismo 400R is the R33-era precursor to the R34 Z-Tune. It proved that Nismo could take the RB26 platform and push it to 400+ PS reliably. The techniques Nismo developed for the 400R — stroker crankshaft, reinforced block, larger turbos — were later used in the R34 Z-Tune and in Nismo's ongoing RB26 tuning programs.

For R33 GT-R historians and Nismo collectors, the 400R is the ultimate R33. It's the car that demonstrated what was possible when the corporate limits were removed. And with only 44 ever built, it's one of the rarest production cars ever sold under the Nissan name.
