Brian Crower Stage 2 F/I Camshafts for Honda/Acura B-Series

Brian Crower Stage 2 Forced Induction Camshafts - B Series

You're running boost on your B series and the stock cams are holding you back? Once you start making real power with a turbo or supercharger, the factory cam timing doesn't work anymore. The Brian Crower Stage 2 forced induction cams are built specifically for boosted B series motors. These aren't just aggressive cams that happen to work with boost. They're designed from the ground up to make power under boost. You're getting shorter duration and reduced overlap so you're not blowing compressed air straight out the exhaust. The high lift pulls more air in when the turbo's doing work. If you're serious about making power with boost, you need cams that are designed for it. These are.

Here's Why Boost Changes Everything

Naturally aspirated cams don't work right on a turbo motor. Stock cams are designed for an engine that's pulling air in at atmospheric pressure. When you add boost, your cylinders fill way easier and backpressure shows up faster. The wrong cam timing - especially too much overlap - means you're pushing compressed air from the turbo straight out the exhaust valve before it even burns. You're wasting boost and killing power. The Stage 2 forced induction cams fix that. Shorter duration means less overlap. The intake valve closes earlier so you're trapping that compressed air in the cylinder instead of blowing it out. High lift means the valves open farther so you're moving more air when the turbo's spooled. You get a stronger midrange, better pull past VTEC, and a powerband that actually makes sense for a turbo car.

These Aren't Universal Cams

Brian Crower doesn't just grind aggressive cams and call them turbo cams. These profiles are dyno-tested on actual turbocharged and supercharged B series motors. The cam timing's optimized for engines that see real boost - not just 5 psi on a stock motor. We run these exact cams on our own turbo builds and the difference is obvious when you log it. Your airflow doesn't fall off when you lean on the car. Power keeps pulling instead of nosing over early. That's what you're paying for - a cam profile that's been proven on boosted motors, not guesswork.

You Need the Right Valvetrain Parts

Don't run these cams on stock valve springs. Boost means higher cylinder pressure and these cams have more lift than stock. Your factory springs can't handle that. They're going to float at high RPM and you're risking bent valves or worse. You need upgraded valve springs and retainers that are rated for your RPM and boost level. Before you buy these cams, make sure you're buying the valvetrain kit too. Brian Crower makes valve spring kits - BC0010 or BC0010S - that are designed to work with these cams. Get the right parts or don't bother installing the cams. Weak valvetrain parts fail fast under boost and high lift.

Note: Requires upgraded valve springs. Don't use stock valve springs with these cams or you'll damage your motor. After you install these cams, get your car tuned on a dyno. The cam timing's completely different from stock so your ECU maps won't be right. You need a tuner who knows boosted B series motors. Without a proper tune, you're leaving power on the table and you might be running lean or knocking under boost.
