The Turbocharged Heart Of The 2017 Honda Civic Type R | Top Speed

The Honda Civic Type R is powered by a 2.0-liter turbocharged four-cylinder constructed from aluminum. It uses Honda’s proven VTEC system to phase the timing of the 16 overhead valves. Rotational mass is kept down thanks to sodium-filled exhaust valves and lightweight pistons. A short blip of the throttle will have the 2.0-liter screaming at its 7,000-rpm redline in very short order. Thankfully, redline isn’t required for making peak horsepower. All 306 galloping ponies are in full stampede at 6,500 rpm and the 295 pound-feet of torque peak at only 2,500 rpm but stays through 4,500 rpm.

Temperatures are kept in check by an intercooler, a radiator, and four separate inlets into the engine bay. The lowest inlet in the grille chills the turbo’s intercooler while the space below the Honda H directs air to the engine’s radiator. The upper slot just below the hood is what feeds fresh air into the intake. Last but not least, the hood scoop is used to push cool air down the backside of the engine while relieving positive air pressure under the hood and thereby reducing lift.

More cooling happens via the oil jets that squirt the underside of the piston and the water-cooled, two-piece exhaust manifold. As for those oil jets, they not only cool the pistons and cylinder walls, they also provide a constant flow of lubrication.

After air leaves the unique exhaust manifold, it travels down a single exhaust pipe. Behind the rear axle, the pipe forks off into three seconds. The outer pipes go to large mufflers, while the center pipe feeds a resonator. The three each feel their own exhaust tip in the center of the bumper. Honda says the center resonator is used to control mid-rev booming inside the cabin, while the outer mufflers move vast amounts of air at high speeds. Interestingly, the center resonator actually generates negative pressure at higher revs. The result is a snarling yet not overbearing exhaust note – both from inside and outside the car.
