I am sorry if this is in the wrong section. I have been looking for an 02 2500 extended cab long bed six speed 4x4 with less than 60,000 miles on it. I previously owned a f-250 (sold) and am hooked on the power of the cummins. My friend has an 02 with the 24v cummins and an edge programmer, it is night and day pulling with his versus my old truck. I have found an 02 that fits my criteria (finally) but it has the ho. motor in it. What is the diffrence in this motor and my friends? Is it as reliable as the standard 24v motor? All that the truck will be used for is towing and possibly the occasional out of town trip. I searched this and did not find anything.I am new and once again i appologize if this is the wrong section. Any help/advice would be greatly appreciated.

As far as I know, they are equally reliable. Just the HO has 10 more HP and six gears. Really the only differences between the two is very minor differences in the fuel injection system.

the six speed only came in the HO's. So if your looking for a 6-speed, its the only way to go. As far as reliability goes, HO's and SO's are the same. stick a ez and rv 275's in there and you'll have one heck of a pulling truck!

Welcome to DTR!
No reliability concerns at all with the HO (ETH engine).... and 6 speeds are preferable for towing in my opinion. Sounds like a nice find. O2's are the best, and last, of the second generation CTD... mostly subtle, but many refinements over previous yrs.

Only difference (due to piston & injector pump design) is - it's harder to add big HP (over 500) to the HO... if you think you might ever head in that direction.

Bigger concern might be the rear end gearing. 3.54's are prefered by most .... unless towing very heavy. That being said, I would not pass up a clean, low mileage truck just because it had 4.10 gears.

Good luck!

Well I am faced with a hard decision. I have found an 02 6 speed ho extended cab 4x4 with 87000 miles on it for around $20,000 and i have also found an 01 model extended cab 4x4 five speed with the plain 24v motor in it and 67000 miles for about the same price. I would like to be able to do some power modification but none over 500hp, I just want to pull (my trailer) like a champ. was the six speed tranny better than the 5 speed? The 01 is owned by a diesel mechanic the other is at a dealer. Also the 01 has a south bend clutch in it, he said it was put in because he was taking it on a long trip, it dosent seem that the new one would need replaced with only 67000 miles though.

The 99's that had 6 speeds weren't a HO motor and I think maybe even a few 00's remember they came with the small input shaft in them. I know of one running around harrison.

blackdiesel

WELL if you would have read his post he said he was looking at a 02 , BUT yes the 99 and 00 have the 1 1/4 inputshaft and the so motor and they are RARE as hen's teeth, but they do exist

Any one have an opinion on the situation that i stated earlier. I need to make a decision. The 01 model has had 2 owners and the current owner has been running some kind of fuel lube in the motor (i assume this helps with the injector pump problem) and seems to have taken very good care of it. Since the 02 is at a dealer i have no idea on how the vehicle has been treated. I have done a car fax on both and no accidents or service records either. Was there any major diffrences in the 02 that would be worth taking the extra 20000 miles for?
Thanks again, Adam

If all features are close enough for you to want either truck I would always go with the one where you can ask the owner questions. Who, what , when, where, why, how....just like in English class!!! You'll feel much more confident and have a better reading on future needs, problems.

does the 01 have rear disc brake, if so it's a 01.5 and no diffrents from a 02, with or with out being a 01.5 I would take it. Check for codes on it, and fuel presure would be nice, first. JMO

Curious! Diesel mechanic or no... you don't replace stock clutch with a South Bend just because your going on long trips?? You do it because you have added HP and the stock clutch won't hold it! Two owners in 67,000 miles and a "story" from present owner would kill it for me.

Rear disks are a BIG plus! Dealer offering any 60 or 90 day protection against mechanical problems?
If it's a good dealership, I'd go that route.

HO has higher compression and more torque. 505 vs 460. It is notceable towing. I believe you will like the HO, as is, for towing. Plus, rear discs on 2002.
Check the codes and put a fp gaige on whatever you buy.
