267-A
Unlock stronger mid‑to‑high RPM performance with the Kelford 267‑A Stage 1 camshaft set, engineered specifically for the Toyota G16E‑GTS 1.6 L turbo 3‑cylinder engine used in the GR Corolla and GR Yaris. These precision‑manufactured performance cams deliver enhanced airflow and extended power potential beyond stock profiles while retaining excellent drivability.
Stage 1 Performance Profile: Aggressive cam timing with 266° intake / 274° exhaust advertised duration paired with 11.50 mm net valve lift for both intake and exhaust — optimized for power gains in upgraded turbo applications.
Boost & RPM Capability: Supports engines running up to approximately 8000 rpm and ~30 psi boost when used with proper valve springs and tuning.
Designed for Turbo Upgrades: Ideal for setups with 48‑54 mm turbochargers making in the ballpark of 350‑500 hp — perfect for stage 1/2 rally, autocross, and spirited street builds.
Aftermarket Valve Spring Requirement: Requires performance valve springs (Spring and Retainer Kit.) to control higher lift and avoid valve float at elevated boost/rpm.
Precision Engineering: CNC‑ground and balanced for reliable operation in demanding performance environments. (Manufacturer standard practice)
Noticeable improvement in mid‑range and top‑end responsiveness compared with stock camshafts.
Better breathing at higher engine speeds, allowing upgraded forced induction systems to realize more power.
Strong foundation for tuned builds — excellent when combined with ECU calibration and supporting mods.
