Introducing the AMTuned V8 R8 4.2L 2006-2015 Twin Turbo Tuner kit! This tuner kit gives customers the bare bones foundation removing the harder to achieve fabrication aspect of modifying your vehicle. Customers have the opportunity to choose their own intercooler options which widely vary in the market. After initial production we will be releasing a full bolt on intercooled kit later in 2024. Our kits are designed to give customers the ultimate street-able enjoyment of throttle response and power on demand. The higher output kit options pair great with our AMTuned Built Engines.

This kit will bolt onto your factory exhaust flanges right behind your catalytic converters. Modification of the catalytic converters is highly recommended as material within them can break off and damage the turbines. Wastegates are external on each bank, they are plumbed back into the merged downpipe. Installation of a AN bung into your oil reservoir is required for the oil drains on the turbo chargers, a weld on bung for the oil reservoir is included in the kit. Coolant, oil lines, and fittings for the turbochargers are included. No permanent chassis modification is required.

Kit contains many turbo options from wallet friendly reliable Pulsar units and also genuine Garrett units. We recommend the G25 Series for those looking to stay within the stock rev limits of the vehicle as the turbine size is smaller limiting flow on the top end, and the G30 series for those looking to make bigger power or rev past the factory rev limit. Turbo options are as follows:

  • PSR Mirrored 4849G (G25 Series) Turbo's. 550-900BHP Goal
  • PSR Mirrored 5449G (G25 Series) Turbo's. 650-1050BHP Goal
  • PSR Mirrored 5455G (G30 Series) Turbo's. 650-1150BHP Goal
