On November 3, 1997, NISO released a racing version
of the Skyline GT-R simply known as the 400R. It was comprehensively upgraded
in every area. Many of these were inspired by the GT-R LM NISMO fielded in the
24 Hours of Le Mans.
It use a larger version of the RB26DETT engine
called the RBX-GT2. This had a larger bore and stoke which meant the block and
cylinder head had to be reinforced. Other upgrades included forged connecting
rods, a forged crank shaft, reshaped pistons, an N1-spec turbocharger. This
produced around 400 bhp and was unique to the 400R.
To match the engine a new intake, exhaust and
intercooler system was fitted. The interior had a leather-wrapped SRS steering
wheel, titanium shift knob, monoform bucket seats.
Body upgraded consisted of wider fenders, side
skirts, rear bumper, front bumper with bigger air scoops, redesigned hood and
rear spoiler made of carbon fiber. 18 x 10 inch wheels called NISMO Nismo
LM-GT1 were fitted.
When R33 production ceased in 1998, NISMO had
produced and sold 44 units for the Japanese domestic market.This made for
395 bhp and 347 lb-ft of torque which was combined with carbon driveshafts and a
carbonfibre rear wing making for the most extreme road-going Skyline yet.
Considering the RB-X engine proved itself at Le Mans and Pikes Peak, the 400R
has some solid motorsport DNA within it and as only 44 examples were ever
produced, you’ll struggle to find one for much less than US$ 85,000 (£ 68,000).
