British outfit Litchfield isn’t convinced Nissan’s Track Edition and Nismo GT-R are enough for some owners.

That’s why it’s just lobbed the LM20 special edition, a turnkey warranty-backed GT-R packing a new realm of power and grip.

Slipped under the bonnet is on a new exhaust system, from turbo to tips, then matched to an uprated fuel system, air intakes, and intercooler. A retuned ECU plays mastermind.

It all amounts to a staggering 496kW and 833Nm, that huge torque peak squeezed through its all-wheel drive system as low as 2100rpm.

For comparison, Porsche’s fastest 911, a Turbo S, needs 6.5sec to reach 99mph.

With such firepower at the driver’s disposal, Litchfield’s tuned its electronic stability and traction control systems to custom standards.

Alcon brakes clamp 400mm two-piece rotors, and are hidden by Rays lightweight track wheels all round. Michelin’s Pilot Sport 4 tyres wrap the rims.

Its front lip’s been redesigned in carbon fibre, along with the grille blade and rear heat vents. The rear spoiler’s also been fitted with an extended carbon fibre lip.

Only 20 units of this special edition will be made, but Litchfield reportedly says it will build more with a different name if the demand is there.
