Whifbitz built 600BHP GR Yaris, the most powerful Toyota GR Yaris in the UK!

Andrew’s GR Yaris came back to us for even more power, it was making 451whp on pump fuel at 2.3 bar boost and its now making 506whp on E50 fuel at 2.5 bar boost, that’s an estimated 600bhp at the flywheel!! This is currently the most powerful Toyota GR Yaris in the UK!! Next step is to setup the launch to see what 1/4 mile times we can get from it.

Spec list and more details about the car can be found on our website here

If you need your GR Yaris tuned or maintained please get in touch, we have various tuning options from just a remap to what you see here depending on your requirements.
