If you own a Nissan GQ Patrol or Nissan GU Patrol with the legendary TD42 engine, you already know why these vehicles have cult status across Australia.

However, despite their strengths, factory power output leaves plenty of room for improvement.

At United Fuel Injection, we specialise in TD42 performance upgrades, including:

• TD42 modified fuel pumps (11mm & 12mm)

• TD42 modified turbochargers (16g, 18g, 21L, 23L)

• Full TD42 turbo conversion kits for naturally aspirated models

• Injectors

• Intercoolers and exhaust systems

• Airboxes and snorkels

• Dyno tuning

• Complete drive-in, drive-out performance packages

Whether you want a mild touring setup or a 300+ horsepower build, we can supply individual components or deliver a complete drive-in and drive-out TD42 performance package.
