Honda B-Series Engines
Honda B-Series made its debut as B16A in Japan in 1988. B-Series was the first engine to have Honda's legendary VTEC (Variable Valve Timing and Lift Electronic Control) system. These high reving machines were the first naturally aspirated engines to produce 100hp/Liter. They are capable of engine speeds up to 9000rpm. Throughout its life span, B-Series had many variations with displacements 1.6L, 1.7L, 1.8L and 2.0L. The outputs of these engine were ranging between 126-210hp. Allthough it has so many variations the basic design differs very little among the B-Series. There are actually two short blocks which are used for the entire series. The main difference between them was the deck height. The one used for B16 and B17 engines (except for B16B) has a deck height of 203.9mm while the short block used for B16B, B18 and B20 engines has a deck height of 212mm. These variations were made possible thanks to different pistons, rods and crankshafts. All parts are interchangable among the B-Series including the transmissions.
B-Series favors Honda's superior engineering. These engines can put out incredable levels of power from small displacements. Excellent combustion chambers of a pentroof design, with a shallow included angle insures that more heat energy is used to drive the piston rather than heat the water jacket. The intake and exhaust ports, as well as the valves, are generously sized and contoured correctly for excellent flow right out of the box. The high performance version such as the B18C5 comes with polished ports as factory standart. B-Series features a lightweight cast aluminum block, a fully counterweighted high alloy steel forged crankshaft and forged high alloy steel rods with large bolts. The oiling system in these engines is so well that no engine failures were reported.
B-Series engines were found on every Integra, Del Sol VTEC, Civic SI, JDM Civic Type R, and CR-V until its production ended in 2001. With its reliability, interchangability and high power output, it became one of the most popular engines among import tuners. Any B-Series engine can be tuned with OEM or aftermarket parts. You can bolt a B16 head to a B20 engine or just blow a B18 with a turbocharger. The combinations for tuning up these engines are unlimited. 300-400 whp outputs from turbocharged engines are very common. If you are planning to build up a Honda engine a B-Series will surely be an option.
