Fast response. Strong top end. No compromise.

This is our upcoming G16-STR64 turbo upgrade on the GR Corolla we are accumulating miles on — showing how quickly it comes on boost and how well it carries power through the top of the rev range.

Tuned on the OEM ECU using EcuTek, this setup delivers a responsive, usable powerband that transforms the G16E powerband while maintaining the drivability the platform is known for.

The OEM fuel system supports roughly 380–400whp, and we’re developing additional upgrades to go beyond that.

For now, enjoy the response.

STR64 development continues.
