    greatings, Its a 210hp non turboed version in an international s2500 dumper truck, loaded it has a severely hard time on anything resembling a slope. I dont need to win any road race championships but it would be skookum to not have folks feeling the need to pass on the shoulder everyday, or feel at least mildly confident I could pull the tag trailer and excavator at close to hwy speeds, it does ok on back roads, but that simply isnt always an option

    Anyway, I can find the stock injector numbers, but not the higher hp versions (well I can find them but not sure exactly what I need to be looking for)
    OR would the better option to be simply turn up the pump, it already spews some tinted smoke, not black mind, but you can tell its working hard

    210 with no turbo is about it. Turn the pump up and you will just make black smoke. (Wasted fuel).

    Those engines were not real strong when new and yours is not any stronger with 30+ years of age on it. Make money with it while you develop a plan to replace it with something about 20 years newer.

    Sorry but there's no easy solutions here. A bunch more fuel with no turbo for more air isn't going to do you any good. A turbo really doesn't help much either- and the pistons are different turbo to non turbo. (i've had both turbo and non turbo).

    There's marine versions that churn out some serious hp, but you don't have a constant source of cold water, and you'll just burn down the motor- they aren't that stout.

    Sell the truck to someone who likes to drive slower than you do.

    P.S. I repowered two 3208 cranes to 8.3 cummins, and would do it again in a heartbeat. Smaller displacement, but much better torque. The cranes have a much higher value than a small dump truck- so I could justify the expense and time to do it. I don't think that it would be worth it for a small dump. Its time consuming, and expensive, the cost would be more than the truck is worth.

    welp, thanks all

    Kinda what i was thinkin, without a turbo its just dickered,

    Its not a small dump truck is the problem, its a full 12yd truck...

    the replacement motor is an option, but right now its spinning 2700 to do 55mph, finding an engine that works with my gearing could be an issue, I dont know enough about detroits to know which to look for, the 8.3 cummins is a good idear but will it run at 2700rpm and how expensive is it going to be to swap all this over...

    I am sitting on a dt466 with a bad head gasket that Im thinking of stuffing in the big truck, but it would involve cutting the fire wall and more stuff i just dont have time for. not to mention that whole gearing issue

    for now, I guess its find a detriot or cummins that will work or run it until I can afford something better

    The turbo really doesn't help. I've had both N/A and turbo versions and couldn't tell much difference torque wise. The horsepower rating was a little more, but torque is what moves the load.

    I don't think you'll find a engine swap very economical, even if you don't count your time to do it. You would be better off spending the $6-7,000 trading trucks.

    For International truck application it appears the 3208 was never offered with a turbo. That doesn't mean to say one could not be installed. Let's face it, marine propulsion versions of the 3208 were available rated from 260 up to 450 BHP (but not for long and I certainly wouldn't want to pay the fuel bill) and had turbos on them that appeared to be the size of a large bucket...... see below.

    If you would like to pursue the option of installing a turbo take a look at your current installation, and estimate whether or not a turbo would fit in that space shown in the above photo when you consider all the extra piping, etc.
    Post your Serial Number and Arrangement Number and I'll have a bit of a dig around.

    The 8.3 Cummins does not pull much over 2000-2100 RPM.

    The turbo 3208 was only 250 HP in a truck. I don't even know why they needed a turbo to get 250 HP out of 10.4 liters, these dinosaurs were at the end of their run by the time the turbo ones came anyway, I think. Probably for emissions reasons.

    factory turbo wont fit without adding the doghouse to the cab, as is it has a flat firewall, samesies for the dt466

    50hp with a turbo will likely help, but i dont think its worth the effort for just 250hp, there be a lot of hills around here,

    Im thinking an 8v71 might be the way to go, 300-375hp similar sized engine, high revving, though noisy.

    HP gets the motor spinning faster, Torque is how much it can spin, they are related to some extent without HP there would be no torque, a motor with massive HP and no torque can spin up real fast, but not pull much, a motor with massive torque and no HP can move a mountain at an idle, but takes a week to gain any speed.

    where I sit now, I have neither, so I cant move much, and it takes a week to get up to 55

    Bonus with an engine swap would be jake brakes, not having them really really sucks

    The turbos did not add horsepower in those engines. They were installed to clean up the smoke.

    As far as I know, an 8V71 is also a 2100 RPM engine and has considerably more torque than a 3208. It would be totally impractical to swap, everything would be against you, but if you are up for the challenge....

    I have a non-turbo 3208 in a Ford.
    Works okay for a 7yd dump.
    I’d read the turbo’d 3208’s had extra compression ring on piston and I think skirt was different so, not as easy as just adding the turbo (‘cause I had been thinking along same lines).

    That's what I was thinkin Darryl.. diff pistons, injectors & crank if I remember correctly.. basically a diff. engine.

    ^^^ Pretty much. A 6v-71T Detroit might be a good fit in the op's truck but that is still a 2100 RPM engine, dunno what he has for a transmission(s) but changing from direct to overdrive might just get him close. 6V-71 is a pretty short engine.

    6V71 only 238 HP, not much more than what is in there now and a whole lot more work than just leaving it alone.

    He mentioned an 8V71 but like I said, I think it impractical.

    You missed the "T" above.

    I see that now, I wonder where the turbocharger might be mounted and if it would fit under the hood? I suppose turbo location could be anywhere depending on what the engine came from. How much bigger would a 6V92 be, also. But I still think it might be a silly idea.

    The turbo would be top mounted on the blower. I did replace a 3208 with a 6V-92T many years back, used a lot of stock parts from junkyard trucks that were 6V-71 powered, It was an easy peasy swap.
    The truck was heavy spec Ford Louisville mixer chassis with a 5x4 trans, I used a 9513 to replace the main, not sure about the rear gears but it would run 64MPH at 2100.
