Kelford is a New Zealand camshaft manufacturer with roots in Christchurch dating back to 1968. Its profiles range from upgrades for street-driven cars to fully built race engines. Choose the cam around the rest of the engine and its intended use, rather than simply picking the longest duration.

This selection is for the Toyota 2JZ-GTE, without VVT-i, HV conversion engine. Profile differences, spring recommendations and required modifications are detailed below.

Manufacturer profile information

Checking heights are shown with the duration figures. Net lift is the net valve movement specified by the manufacturer, while cam lift is listed separately. IVO/IVC denote intake valve opening/closing and EVO/EVC exhaust valve opening/closing. BTDC/ATDC mean before/after top dead centre, and BBDC/ABDC before/after bottom dead centre.

Installation and profile selection

Confirm the exact engine version, valvetrain design and the modifications required by the profile. Check cam timing and valve-to-piston clearance during installation. Springs, lifters and other supporting parts mentioned with a profile are not included unless the profile explicitly states that they come with the kit.
