Stage-4

The cam has an excellent upper RPM power band while still keeping a strong torque curve throughout the 3,000 to 5,000 RPM range. The RPM curve created by the cam makes it an excellent choice for circle track, drag race and even road racing application. This cam requires valve train upgrades.

LC Engineering is constantly striving to improve both the quality and performance of our products. We test our camshafts on the street, race track and off-road. The results are an improved line of camshafts that offer a broader selection of grinds, increased horsepower, and higher quality. All LC Engineering Camshafts are ground on new billets and double heat-treated for long life. Each has been designed for maximum torque and horsepower, specifically for the application. When comparing camshaft profiles, always reference the duration @ .050" valve lift.

NOTE: Will not work with the stock 22RE or 22RTE computer. It requires an aftermarket stand alone engine management system like one of these we offer:

  • Haltech Elite 550 22RE Fuel Management System w/ Sub Harness Kit, see Part #: 1020220.
  • Haltech Elite 550 22RE Fuel Management System w/ Complete Harness Kit, see Part #: 1020221.
  • Pro Fuel Injection Kit #3 Naturally Aspirated 4 Cylinder, see Part #: 1063026.

NOTE: Always check the valve to piston clearance and valve to valve clearance with this camshaft! Piston notching may be required if you do not have .100" of valve to piston clearance at full lift. Failure to install this cam with matched valve train components can cause engine damage. LC Engineering highly recommends using our Pro Camshaft Kit to allow proper spring retainer to guide clearance for any cam that has over .450" lift or in any application that requires a sustained RPM of 6,000 or higher.

  • Pro Camshaft Kit, see Part #: 1020000.

NOTE: LC Engineering will not warranty any cam damage if you do not purchase new Toyota rocker arms from LC Engineering, or a complete rocker arm assembly from LC Engineering at the same time as purchasing our camshaft.

  • Individual rocker arms, see Part #: 1023015.
  • Complete rocker assembly, see Part #: 1023018.

Buyer beware on reground rockers in the market. Regrinding the pad on the rocker can remove the heat treated portion of the pad making for a soft rocker. Rocker arms that are reground will not have the factory geometry of a stock rocker. To regrind a rocker will take care of the face surface but will do nothing to address the rocker shaft bore, a loose rocker bore will make adjustment difficult and will never be correct which is why we cannot warranty a camshaft unless new rockers are purchased with a camshaft.

Just got my newly built motor started with this cam and it sounds insane, haven't broken in the motor enough to do a full pull with it yet but you can check out the idle sound here:
