2005-2006 Cobalt / Pontiac G5 2.2 Ecotec Swap Kit - Harness, Throttle Body & Tuned ECU

The factory ECU on the 2005-2006 Chevy Cobalt and Pontiac G5 2.2 is not supported by tuning software. This kit swaps the car to 2003-2005 Cavalier/Sunfire engine management, which can be tuned. This swap is for race cars only.

What's in the kit

• 2.2L Ecotec L61 Standalone Wiring Harness, all new components
• Ported and Bored 60mm 2.2L Ecotec Throttle Body, no core required
• Tuned 2003-2005 Cavalier/Sunfire ECU for your transmission (manual or automatic), shipped tuned and ready to install

What you still need

• Throttle pedal and cable from a 2003-2005 Cavalier or Sunfire
• Your stock fuel injector harness, which the SBR harness reuses
• Your TPS and IAC from the stock throttle body, which transfer to the 60mm unit

The harness is a standalone engine management harness and does not include a gauge cluster connection.

Before you order

Put your cam, intake and fuel octane in the notes box on the cart page so the ECU is tuned for your build. Automatic transmission harnesses are built to order, so allow about 2 weeks.
