Lamspeed Racing Toyota G16E-GTS GR Yaris/Corolla Race Cylinder Head.
Over the past 9 months we have been testing our race cylinder head on both the drag strip and the circuit at World Time Attack 2023. As with all our products, we first develop and test it in our own GR Yaris before releasing it to the public.
As of the beginning of 2025 we have refined our G16E-GTS cylinder head package starting off with a few hand ported iterations. When we found our desired port shape that net us the gains we desired on the dyno this was then put to the test in a real life race scenario. Both our World Time Attack Circuit and Drag GR Yaris both now run our CNC ported cylinder head package with the gains showed below in the images of the before and after dyno graphs along with real life results.
Proven results!
