Configuration SOHC 60° V6
Chronology
Predecessor Honda C engine

The J-series is Honda's fourth V6 engine family, introduced in 1996. It is a 60° V6 – Honda's existing C-series were 90° engines. The J-series was designed for transverse mounting. It has a shorter bore spacing (98 mm or 3.86 in), shorter connecting rods, and a special smaller crankshaft than the C-series for compactness. All current J-series engines are gasoline-powered SOHC 4-valve designs with VTEC variable valve timing.

The J-series engine was designed in the United States by Honda engineers. It is built at Honda's Anna, Ohio and Lincoln, Alabama engine plants.

One unique feature of some J-family engine models is Honda's Variable Cylinder Management (VCM) system. The system uses VCM to turn off one bank of cylinders under light loads, turning the V6 into a straight-3. Some versions Variable Cylinder Management system were able to turn off one bank of cylinders or one cylinder on opposing banks, allowing for three-cylinder use under light loads or four-cylinder use under medium loads.

J25[edit]

The J25A was only used in the Japanese domestic motors Inspire/Saber models. The J25A displaced 2.495 L (152 cu in), Bore was 86 mm (3.4 in) and stroke is 71.6 mm (2.82 in). The J25A used a 10.5:1 compression ratio and was a SOHC VTEC design. Output was 200 hp (149 kW) @ 6200 rpm and 24.5 kg·m (177 lb·ft) of torque @ 4600 rpm. It had variable intake manifold to optimize torque output at all engine speeds and engine response.[1]

J30A[edit]

The J30A displaces 2,997 cc (2.997 L; 182.9 cu in) and is a SOHC VTEC design. Bore is 86 mm (3.4 in) and stroke is 86 mm (3.4 in). Output for the light weight 250 lb (110 kg) J30A1 was 210 hp (160 kW) @ 5500 rpm and 200 lb·ft (270 N·m) of torque @ 4800 rpm. The J30A4 pushed output to 242 hp (180 kW) and 212 lb·ft (287 N·m) using a three-way VTEC system, higher (10:1) compression ratio, and a novel exhaust manifold cast as one piece with the cylinder head. It weighs nearly 20 lb (9.1 kg) less and is an inch shorter than J30A1. This version was on the Ward's 10 Best Engines list for 2003 and 2004. The IMA hybrid version was on the list for 2005. In 2006 to mark the 30th anniversary of the Accord, Honda created the J30A5, which boosted output to 244 hp (SAE Net 08/04) and 211 lb·ft (SAE Net 08/04) of torque. According to Honda, horsepower gains were achieved with improvements to the airflow of the intake and exhaust system.

J32A[edit]

The J32A displaces 3.2 L (195 cu in) and is a SOHC VTEC design. Bore is 89 mm (3.5 in) and stroke is 86 mm (3.4 in). Output was 225 hp (168 kW) @ 5600 rpm and 217 lb·ft (294 N·m) @ 4700 rpm for the J32A1, with the J32A2 raising output to 260 hp (194 kW) @ 6200 rpm and 232 lb·ft (315 N·m) @ 3500-5500 rpm. A more aggressive camshaft, more free flowing intake/exhaust, and a 2-stage intake manifold all result in a 33.55 hp (25.02 kW) increase over the J32A1. The J32A3's output in the 2004/2005 TL is 270 hp (201 kW). SAE changed the way they tested engine  hp for the 2006-2008 TL is 258 hp (192 kW). The J32A3 also includes the one-piece exhaust manifold cast with the cylinder head, first introduced on the J30A4.
