1st gen. cummins vs. 2nd gen

What is the differences in these cummins engines? Also, are they basically the same way to bomb them. I have been reading over on TDR about the 1st gen's, and cant seem to find the differences(maybe I'm not looking hard enough). Which one is costlier to bomb? I would like to get a cummins before next summer, and am trying to make up my mind on which one I want to get.

I like the 1st gen's body style, but I also like the 2nd gen's body style too. It is a tossup between the 2, although I do like the manual hubs on the 1st gen. What kind of price can I expect to pay for something like a '92 or '93 4wd cummins 250(these years would have had an intercooler)? We don't really have many for sale around here, just mainly 2wd. How about the price on a 95-96 cummins? I want one with a manual tranny also.

I would be using this truck as a dd most of the time, and also as a sled-pulling machine. It would need to be reliable, and powerful too. It seems to me that there isn't much stuff out there for the 1st gens, but maybe I'm not looking in the right place.

Thanks for the help, and I am starting to put some money aside to HOPEFULLY buy me one Very Happy

i've drove 1st gen 2wds plenty of times, they weren't great but with a little bit of tweaking I'm sure they'd be fine. We had one at work with probably 500,000 miles on it, the speedo/odometer stopped working about 5 years ago in the high 280,000 some thousand miles. We drive it a lot during the summer time, and it runs good. Just don't know the engine differences(same 5.9L cummins, but what else has changed?) in the 1st and 2nd, and which one would be cheaper/easier to mod?

The first gen had a different injection pump and the newer of the first where intercooled. The second gens have an injection pump with a lot more potential (p7100)and are really easy to tweak.

to be honest with you, the 2nd gen is the best one of the two for sure, the 12v's from 1994-1998.5 were some of the greatest and easiest engines to work on and upgrade, hence this is why I got one, because, I love diesels of coarse, but because of the ease of working on them, and the ease of upgradeing them, plus 600+ lbs of torque and being able to tow anything is that sh*t. The 1st gens are a good engine, but they need to be tweeked in a few areas to be a really good engine, they have good potential, and could be pretty close to a 2nd gen. If it were me going to buy one of the 2 it would be the second gen, the truck also just looks better, and there are a few more around then the first gen cummins to get. Hope this helps. -jordan

for a good first gen 4x4, intercooled ctd you looking anywhere from 4-8 thousand depending on miles and condition, and usually on the higher end

First gens used a VE rotary injecton pump. Put out less pressure and less CC's than the 2nd gen P7100 pump as said above.

They were intercooled after 91.5 but of the stock trucks I've driven the earlier trucks had more nuts. Also the pre 91.5's used a 9mm injector tip which caused some heads to crack around the injector well. The later used a 7mm tip which cured the cracking. 89-91.5's had the 727 3spd auto with Dana61/71 axles that are now very hard to find parts for. 91.5-93's used A518 or 46RE overdrive non lockup tranny. All years had the same Getrag 5speed which had reliability issues.

They are a little harder to get power out of, and the trucks themselvs have some quirks but its doable. A friend of mine dynoed over 520hp with his twinned 93 with the stock POS getrag tranny with an upgraded clutch. Think he did 580ish with watermeth.

Thanks everybody, you confirmed my thoughts that the 1st gens were harder to modify, but I didn't know exactly why. I will probably get a 2nd gen 12v, just because they are easy to work on also.

How much am I looking at for a 95-97 cummins 2500? Don't care about mileage, as long as it isn't some outrageous number. I believe I saw a 94 around here for $5000, and one of my buddy's friends sold a 98 for $10,000 with 60,000 miles, if I had the money I would have definetely got that one.
