Hennessey Performance engineering of Texas has a new, 600 hp upgrade for the Nissan GT-R. Included in the package is electronic boost control, better air induction, and a front-mount intercooler system.

Hennessey Performance Engineering has just made us even bigger fans of the Nissan GT-R. The Texas-based tuner released a 600 hp (441 kW) upgrade to the car just in time for the holidays.

Called the Godzilla 600, the tuning package also provides up to 570 ft-lb (773 Nm) of torque.

This is not the first GT-R specific upgrade from the company. They have a tweek to the on-board computer software that adds 65 hp (48 kW) and 75 lb-ft (102 Nm) of torque after only 10 minutes.

The Godzilla 600 is not as simple. This package includes an upgrade to the air induction system, electronic boost control, an improved wastegate actuator, and front-mount intercooler system. Also included are turbo down pipes, mid-pipe exhaust, and rear section exhaust all in stainless steel.

Hennessey will install the package for $14,500, or ship the items to you for $11,500.

We wonder how soon you will notice the difference as you try to outrun Texas Department of Public Safety Highway Patrol as you race down I-10 away from HPE headquarters.
