#138448 The J-series was Honda's second V6 engine family, introduced in 1996. It is a 60° V6 – Honda's existing C-series was a 90° engine. The J-series was designed for transverse mounting. It has a shorter bore spacing (98 mm/3.86 in), shorter connecting rods, and a special smaller crankshaft than the C-series for compactness. All current J-series engines are 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 engine plant.

One unique feature of some J-family engine models is Honda's Variable Cylinder Management (VCM) system. The system uses the i-VTEC system to turn off one bank of cylinders under light loads, turning the V6 into a straight-3. The latest Variable Cylinder Management system is 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
The J25A was the first J-series engine produced. It was only used in the export-model Inspire/Saber models, however. The J25A displaced 2.5 L (~153 cu in) and was an SOHC Gasoline direct injection VTEC design. Output was 192 hp (143 kW).

J30

The J30 displaces 3.0 L (~183 cu in) and is a SOHC VTEC design. Output for the light weight 250 lb (110 kg) J30A1 was 200 hp (150 kW) and 195 lb·ft (264 N·m) of torque. The J30A4 pushed output to 240 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) lighter 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 ft·lbf (SAE Net 08/04) of torque. According to Honda, horsepower gains were achieved with extensive improvements to the airflow of the intake and exhaust system.

J32

The J32 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) 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, freer flowing intake/exhaust, and a 2-stage intake manifold all result in a 35 hp (26 kW) increase over the J32A1. The J32A3's output in the 2004/2005 TL is 270 hp (201 kW). SAE corrected 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.

J35

The J35 displaced 3.5 L (3471 cc, 212 cu in) and is an SOHC VTEC design. Bore is 89 mm (3.5 in) and stroke is 93 mm (3.7 in). Output was 210 hp (157 kW) for the J35A1; 240 hp (179 kW) and 253 ft·lbf (343 N·m) (5800/4400 rpm) for the J35A3; 240 hp (179 kW) and 242 ft·lbf (328 N·m) (5500/4500 rpm) for the J35A4.

The J35A5 used in the 2004 - 2006 Acura MDX produces 265 hp (198 kW) at 5800 rpm and 250 ft·lbf (339 N·m) at 3500 rpm. The 2003 version of this engine produces 260 hp (194 kW) at 5750 rpm.

The new J35 used in the Acura RL produces 290 hp (220 kW) at 6200 rpm and 256 lb·ft (347 N·m) at 5000 rpm. This engine was on the Ward's 10 Best Engines list for 2005 and 2008.

The J35A9 used in the 2006 - 2008 Honda Ridgeline produces 247 hp (184 kW) at 5750 rpm and 245 lb·ft (332 N·m) at 4500 rpm.

The J35A3 was also used by General Motors in the 2004-2007 Saturn Vue, though it utilized the cast-iron crankshaft from the J35A4 rather than the forged-steel version of the J35A3. GM refers to it as the L66.
