Can someone tell me how to tell the difference between the standard and HO cummins without tearing one down. Also were the HO started in 2000. The standard 5.9 run was up to 2004 and then only HO.

HO and so  engines have a data plate on the side of the timing cover 245hp is a HO also HO engines came with a 6spd trans HO run higher comp pistons and higher fuel pressure .If you have just a bare engine the data tag (245 hp) is the thing to look at

i may be wrong but i thought the HO engines were rated at 305 hp and not 245

i copied this from another tread from another member on this site


"The 2003-early 2004 Dodges could be had with the H.O. (high output) Cummins (305hp / 555 lb-ft) and are generally known as about the most fuel efficient Cummins you can buy. They were available with the NV-5600 6-speed manual trans (nearly un-breakable)or the 48RE automatic, a pretty respectable trans stock if you don't get too power crazy (+60-75hp max). After 2004.5, they went to the Cummins "600" (and later the "610"), the numbers referring to the torque rating. There were rated at 325hp, but also had some emissions programming in the ECM and catalytic converters. The H.O. engines had non of this.

"To identify which engine is in a particular truck, look on the drivers side of the black valve cover on the top of the engine. There is a tech sticker that will display the hp rating of the engine. 245-250 hp is the S.O. (standard output-only available with 5-speed manual or 47re automatic trans), 305hp is the H.O. engine, 325hp is the Cummins 600 or 610 which started in 2005. "

The H.O Engine was started in 01. The 01 and 02 H.O. use a different Injection pump than the S.O. It's still a vp44 but is designed a little different and has different ECM programming. It also has a little higher compression.  The 01 and 02 H.O are rated at 245 Hp with the 6-speed and 235 with the atoumatic.

I don't really know much about the differences in the 03< H.O. engines.

the compression was the same, stroke, bore, everything was the same, just different tuning in the ECM and a better flowing vp44 and slightly bigger injectors from bosch, everything else was the same. actually some guys are finding that the 01 and 02 vp44 will make more horsepower then the hotrod vp44, especially with a programer o r tuner installed

Bore,Stroke was the same but it runs higher compression.

H.O.
Peak Torque      505 lb-ft (from 1600 to 2700 rpm)

Advertised Power      245 hp @ 2700 rpm

Governed Speed        3200 rpm
Compression Ratio   17:1
Maximum Boost       26 psi
Turbocharger            HX35W

S.O.

Peak Torque     460 lb-ft (from 1600 to 2700 rpm)
Advertised Power     235 hp @ 2700 rpm
Governed Speed       3200 rpm
Compression Ratio  16.3:1
Maximum Boost       20.8 psi
Turbocharger            HY35W (Auto), HX35W (Man)

What's new in the ETH engine:

Electronic Controls: New ECM calibration and fueling algorithms.

Fuel Pump: Increased fuel flow in the Bosch VP44 injection pump.

Injectors: Designed to provide increased fuel flow.
Injector note posted to the TDRoundtable by tgbol:
ETH injectors (3946306) flow 600cc at 100bars for 30 seconds
ETC injectors (3944828) flow 640cc at the same test.

Turbocharger: Revised wastegate setting for 26psi at the turbocharger outlet.
Manifold boost specification is 43.5 inches Hg / 21 psi

Head: Valve seat inserts for added durability.

Pistons: New pistons with higher 17:1 compression ratio.
Flywheel: New flywheel with 330 mm diameter clutch (vs. std. 310 mm).
FWIW: Reports from owners indicate that ETC engines are more responsive than ETH engines are to the major fueling boxes.


I got my information from here: http://dodgeram.org/tech/dsl/Facts/01ISBspecs.html

Also I've been told the an H.O. pump will actually flow less fuel than an S.O. pump when fueling boxes are used. The H.O. uses smaller plungers to make higher fuel pressure. It also has a more aggressive fueling cam than the S.O. Now I have been told that a Hot Rod VP44 is nother more than a mix of the S.O. pump's bigger plungers with the H.O. pump's more aggresive fueling cam.

However most of the above has been told to me second hand. Do you have a more reliable source for your information?

They mention the higher compression numbers in my '02 owners manual. My buddy has a '02 5spd truck and it's rated at 235hp. When we did our VP-44's his was a 025 pump and mine was a 027 and the Freightliners run a 029. I was told if you try putting a 027 pump on a 235hp motor it won't run worth a pooh. Also there must be something different on the 245 HO HX35 turbo, because the Banks Quick turbo housing upgrade will only fit the 245 HO trucks...there pretty specific about that.
