Brian Crower Stage 2 Forced Induction Camshafts for H Series

Brian Crower Stage 2 Forced Induction Camshafts - H22

You're running boost on your H22 Prelude and the stock cams aren't cutting it? The Brian Crower Stage 2 forced induction cams are built specifically for turbocharged or supercharged H22 motors. These aren't generic performance cams. They're designed from the ground up to make power under boost. Short duration reduces overlap so you're not blowing compressed air out the exhaust. High lift pulls more air in when the turbo's spooled. If you're serious about making power with boost on an H22, you need cams that are actually designed for it. These are.

Here's What Makes These Different

Stock H22 cams are designed for a naturally aspirated motor. When you add boost, everything changes. Your cylinders fill easier, backpressure shows up faster, and too much valve overlap means you're pushing compressed air straight out the exhaust before it burns. You're wasting boost and killing power. The Stage 2 cams fix that problem. The short duration profile cuts down overlap so the intake valve closes earlier. You're trapping that compressed air in the cylinder instead of blowing it out. The high lift - .486" intake and .465" exhaust at the valve - means the valves open farther when they're open. More air moves through when the turbo's doing work. You get sharper throttle response, better cylinder fill, and more power across the RPM range.

BC Doesn't Guess on Cam Profiles

Brian Crower precision-grinds these cams using small diameter grinding wheels. That creates an aggressive ramp rate - the valve opens faster and gets to full lift quicker. More aggressive ramp means better cylinder fill. Every cam profile's dyno-tested on actual H22 motors before it goes into production. The numbers you're seeing aren't marketing claims. They're real dyno numbers from real engines. We run BC cams on our own turbo builds because they work. That's what you're paying for - a cam that's been proven on boosted motors, not guesswork.

You Need the Right Valve Springs

Don't run these cams on stock valve springs. The higher lift and faster ramp rate will float your stock springs at high RPM. You're risking bent valves or worse. You need upgraded valve springs, retainers, and seats that can handle the load. Brian Crower makes two valve spring kits for these cams - BC0030 for race applications and BC0030S for street use. The BC0030's stiffer for high-RPM race builds. The BC0030S is designed for street cars where you want reliability and long-term durability. Pick the kit that matches how you're using the car. Before you buy these cams, make sure you're buying the valve spring kit too. Don't cheap out on valvetrain parts when you're running boost and aggressive cams.

Note: Requires BC valve spring kit BC0030 (race) or BC0030S (street). Don't use stock valve springs with these cams or you'll damage your motor. Professional installation's recommended. 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 H series motors. Without a proper tune, you're leaving power on the table and you might be running lean or knocking under boost. These cams are designed for forced induction. If you're running a naturally aspirated H22, you want different cams.
