Crow Cams Nissan TB42/TB45 Custom

A custom-ground camshaft for a TB42/TB45 engine build. The profile is agreed with BBT before production; there is no fixed numerical cam card for this SKU.

Camshaft specifications

Supplied contents

One camshaft. Springs, retainers, installation hardware are separate.

BBT installation support

Have the installer verify cam timing, piston-to-valve clearance, spring installed height, coil-bind and retainer-to-seal clearance on the actual engine. Confirm the lash or preload procedure for the supplied cam and follow its lubrication and run-in instructions. BBT can assist with part selection, installation and calibration.

Custom-ground camshaft ordering

SKU 442900 is a custom-ground Nissan TB42/TB45 camshaft rather than a fixed shelf profile. Cam timing, duration, lift and lash requirements must be agreed for the actual engine combination before the order is placed.

Information BBT needs

Provide the exact engine, cylinder-head specification, compression ratio, induction, exhaust, intended fuel, transmission, vehicle use, target RPM range and any existing valvetrain modifications. BBT can then confirm the appropriate custom profile and the springs, retainers and supporting hardware required for that profile.

BBT selection and installation support

Built by Boost & Tune can confirm the correct Crow component against the camshaft, cylinder-head, valvetrain and engine combination before supply. Where dimensions or clearances are critical, final selection must be based on the actual engine components and measured assembly rather than vehicle model alone.

Custom-order confirmation

This SKU represents a custom/order-specific camshaft service rather than one universal fixed cam card. The required profile must be confirmed against the engine specification before production. BBT can work through the intended use and supporting valvetrain requirements before the order is committed.
