On the turbocharged G16E-GTS, a high flow downpipe, a cold air intake and a custom tune are the core power parts, since together they change exhaust flow, airflow, boost and fueling. We offer the LIMIT+1 GR Corolla High Flow Downpipe + Midpipe w/ EPA Approved GESI Cat and EcuTek custom tuning through LIMIT+1 x Boosted Performance Tuning, as well as LIMIT+1 GR Corolla Power Packages 1 to 3.

Next steps include a turbo inlet, an upgraded intercooler and the LIMIT+1 x Delicious Tuning GR Corolla Flex Fuel Kit, which lets a matching tune use ethanol blends such as E85. For larger builds we carry Injector Dynamics injectors, the Artec GR Corolla Sport 400 Bolt-On Turbo Kit and the LIMIT+1 GR Corolla G16E-GTS Performance Cylinder Head.

The G16E-GTS is a turbocharged 1.6 liter three-cylinder, and how it holds up when modified depends mostly on how far the build goes and how well it is supported. Heat control, fuel quality and a conservative custom tune matter most as power goes up, which is why oil coolers, intercoolers and a proper flex fuel setup are part of a well planned build.

For higher power builds, we carry upgraded engine parts such as the LIMIT+1 GR Corolla G16E-GTS Performance Cylinder Head, HKS and CP Carrillo pistons and rods, and ARP and Lamspeed head studs.

Under the Magnuson-Moss Warranty Act, a dealer cannot void an entire factory warranty simply because aftermarket parts are installed. A specific claim can still be denied if a modification is determined to have caused the failure, and ECU changes are detectable. Warranty decisions are made by Toyota and its dealers, not by LIMIT+1.

Every product page lists the model years, trims, and drivetrain configurations the part is built for, and every collection on this site is organized by platform. If your vehicle carries other modifications, or you are between model years or trims, send us your year, trim, and current setup before ordering and we will confirm fitment.
