![]() According to Honda, horsepower gains were achieved with improvements to the airflow of the intake and exhaust system. In 2006 Honda created the J30A5 to mark the 30th anniversary of the Accord. The IMA hybrid version was on the list for 2005. This version was on the Ward's 10 Best Engines list for 20. It weighs nearly 20 lb (9.1 kg) less and is an inch shorter than J30A1. The J30A4 pushed output to 242 hp (180 kW) and 212 lb⋅ft (287 N⋅m) using a three-way VTEC system, a higher (10.0:1) compression ratio and a novel exhaust manifold cast as one piece with the cylinder head. Output for the lightweight (Actual complete running engine including flywheel, less starter is 152 kg) 250 lb (110 kg) J30A1 was 210 hp (157 kW) at 5500 rpm and 200 lb⋅ft (271 N⋅m) of torque at 4800 rpm. ![]() The J30A displaces 2,997 cc (3.0 L 182.9 cu in) and is a SOHC VTEC design. It had a variable intake manifold to optimize torque output across varying engine speeds and engine response. The J25A used a 10.5:1 compression ratio and was a SOHC VTEC design. The J25A was used only in the Japanese domestic Inspire/ Saber models. Some versions were able to turn off one bank of cylinders or one cylinder on opposing banks, allowing for three-cylinder use under light loads and four-cylinder use under medium loads. Initially, the system turns off one bank of cylinders under light loads, turning the V6 into a straight-3. One unique feature of some J-family engine models is Honda's Variable Cylinder Management (VCM) system. VTEC variable valve timing is used on almost all applications, with exceptions being the J30AC and J35Y8 (which use Variable Timing Control instead). All J-series engines are gasoline-powered, use four valves per cylinder, and have a single timing belt that drives the overhead camshafts. It has a shorter bore spacing (98 mm (3.86 in)), shorter connecting rods and a special smaller crankshaft than the C-series to reduce its size. Also unlike the C series, the J-series was specifically and only designed for transverse mounting. The J-series is a 60° V6 unlike Honda's existing 90° C-series engines. It is built at Honda's Anna, Ohio, and Lincoln, Alabama, engine plants. The J-series engine was designed in the United States by Honda engineers. The J-series is Honda's fourth production V6 engine family introduced in 1996, after the C-series, which consisted of three dissimilar versions.
