Nissan GT-R is one of the most appreciated sports cars among tuners; but if you ask us, it needs no upgrades. Still, the folks over at Litchfield are offering new performance upgrade options for the GT-R that manage to take the output up to an amazing 750 horsepower.

The tuner is offering five different upgrade stages for the GT-R, with a sixth one under development and promising to raise the output to a total of 1,000 horsepower.

The upgrades include changes from small ECU recalibration or new Y-Pipe for the exhaust system up to the addition of new Turbo intake pipes or improved boost control.

The prices for the upgrade differ depending on the stage the customer selects and will range from £1,095 ($1,700) for stage 1 and up to £14,895 (about $23,000) for stage 5.
