Description
Cat Cams Camshaft 263°/267° – BMW 4cyl 1.6L 16V SOHC (R53) is a performance camshaft profile from Cat Cams, developed for the BMW 4cyl 1.6L 16V SOHC engine. Cat Cams has built valvetrain components in Belgium for decades, and every profile is ground to motorsport tolerances rather than adapted from a generic blank.
Key Features:
- 263°/267° duration: an intake and exhaust profile matched as a pair, so the engine gains area under the curve without losing driveability.
- 10.00mm intake / 8.50mm exhaust valve lift: increased lift flows more air through the existing head without requiring further machining.
- Billet steel construction: machined from solid billet steel for maximum strength, holding its profile under sustained high-rpm loading.
- Correct valvetrain match: ground specifically for the BMW Mini SOHC 16v configuration, so it drops into the standard head.
- Made to order: ground to spec by Cat Cams in Belgium, so the profile arrives fresh rather than off a shelf.
Fitment:
- BMW 4cyl 1.6L 16V SOHC – engine code R53
- BMW Mini SOHC 16v valvetrain
Camshaft changes of this size normally want matched valve springs and a revised tune to realise the profile fully — talk to us if you want the supporting parts specified alongside it.
