The cummins 5.9L diesel engine is available at Roadmaster Engine.

CUMMINS 5.9L DIESEL ENGINE

The 5.9 litres (360.0 cu in) ISB (Interact System B) is one of the largest straight-six engines ever produced for light truck vehicles, in addition the improved high output 600 version was on the Ward’s 10 Best Engines list for 2004.

One unusual feature of the ISB is that it is a multi-valve pushrod engine design. The engine displaces 5,883 cubic centimetres (359.0 cu in), with a 102.1 millimetres (4.02 in) cylinder bore and 119.9 millimetres (4.72 in) piston stroke.  Consequently a turbocharger is used to increase the output in the high-compression (17.2:1 in recent versions) diesel.  Finally it is an all-iron engine with forged steel connecting rods, an assembled camshaft, and a cast aluminum intake manifold. The engine is produced in Columbus, Indiana.

Therefore, Roadmaster Engine offers these cummins 5.9L diesel engine for only $4550 exchange.

Dodge Ram ISB, cummins 5.9L diesel engine

Midway through model year 1998, the Dodge Ram switched from the 6BT to the ISB to meet updated emissions requirements. Like other ISB’s, these engines started out using the Bosch VP44 rotary injection pump. The VP44 setup meant that timing and fuel could be precisely controlled, which led to cleaner emissions. However, VP44 failure rates were very high versus the older P7100 injection pump. Therefore the compression ratio in these engines was 16.3:1. The 1998-2000 ISB was rated at 215 horsepower (160 kW; 218 PS) and 420 pound-feet (569 N·m) when equipped with the 47RE automatic transmission. Since the 1998 ISB was rated at 235 horsepower (175 kW; 238 PS) and 420 pound-feet (569 N·m) due to being equipped with the manual transmission.

1999 CUMMINS 5.9L ENGINES

So the 1999-2000 ISB was rated at 235 horsepower (175 kW; 238 PS) and 460 pound-feet (624 N·m) when equipped with a manual transmission. For the 2001-2002 model years, a standard output and high output ISB Cummins engine was offered. The standard output, which was the same as the previous engines was rated to 235 horsepower (175 kW; 238 PS) and 460 pound-feet (624 N·m) when equipped with either a manual transmission or automatic.

The high output ISB was rated at 245 horsepower (183 kW; 248 PS) and 505 pound-feet (685 N·m), and only a NV5600 six-speed manual transmission was offered behind it. The high output engine was different in a few ways from the standard output engine. The high output ISB had higher compression (17.1:1), powdered metal valve seat inserts and a larger flywheel. The Bosch fuel system was reworked as well to allow increase fuel delivery and a slight increase in timing.

Dodge Ram ISB CR

For the 2003 model year, the Cummins was introduced with Bosch high pressure common rail fuel injection, again increasing power output. On automatic equipped vehicles, the 47RE was upgraded internally to increase durability and torque capacity, now known as the 48RE. The 2003 rating for the Dodge truck was released at 305 horsepower (224 kW; 308 PS) and 555 foot-pounds (752 N·m). Midway through the 2004 model year, the Cummins 600 was introduced, producing 325 horsepower (242 kW; 330 PS) at 2,900 rpm and 600 pound-feet at 1,600 rpm.

Hence 12 and 24 valve cummins 5.9L diesel engines are no problem for Roadmasters diesel engine builders.
