Drag Cartel Modified VTC Cam Gear for K20A/K20Z/K24A

Drag Cartel Modified VTC Cam Gear - Honda/Acura K20A, K20Z, K24A

Running aggressive aftermarket cams on your K series and need to limit VTC advance? The Drag Cartel modified VTC cam gear mechanically limits how far the VTC system can advance the intake cam. The factory RBB cam gear advances up to 50 degrees, which is fine for stock cams but causes piston-to-valve contact when you're running high-lift, high-duration aftermarket cams. This modified gear limits advance to 30, 35, 40, or 45 degrees depending on which one you order, which prevents the valves from hitting the pistons at high RPM.

Why You Need a Modified VTC Gear

When you install aftermarket cams with more lift and duration than stock, the valve timing gets more aggressive. If the VTC system advances the intake cam too far at high RPM, the valves open earlier and lift higher than the piston can clear, and the valves smack into the pistons. That destroys the engine. A modified VTC gear mechanically stops the advance at a safe angle for your specific cam profile so the VTC system can't advance far enough to cause piston-to-valve contact.

Four Advance Limit Options

Drag Cartel offers four different advance limits: 30, 35, 40, and 45 degrees. Which one you need depends on your cam profile. More aggressive cams with higher lift and longer duration need less advance, so you'd run a 30 or 35 degree gear. Milder cams can run more advance, so you'd use a 40 or 45 degree gear. Check with your cam manufacturer or tuner for the recommended advance limit for your specific cams. Drag Cartel can also custom cut a gear to a specific advance limit if you need something outside the standard options.

CNC Machined from OEM Gears

Drag Cartel starts with brand new OEM RBB VTC gears and CNC machines the stop to the advance limit you ordered. The machining exceeds OEM tolerances so the gear fits and functions exactly like the factory gear, just with a mechanical stop that prevents excessive advance.
