factory turbo motors

[HETvet]

I'm in the market for a deuce but I had some unanswered questions. What were the factory turbo engines that came in these things? Next would be my options for a repower? I'm not looking for a race car; more so a family weekend camping trip worker/hauler. I also plan to run 53 inch tires. Thanks in advanced for any and all information yall might have for me.

Hercules and Continental were two of the original manufacturers and the Cummins 5.9 seems to be the most popular re-power option although I just saw a picture of someone who had put a Cummins 8.3 in one.

Use search to find threads but here is one of the best.

Thank you for the input. I was thinking about re powering with the 6cta my self. I'm going to continue to do my research, but really appreciate any other information. Thanks again

I have access to CAT c7's and Allison transmissions that came out of running trucks, some are still in the front half of the frame with radiator, intercooler, and everything else. I heard a number from the mechanic but am not sure of it, I don't know what it would take to install it in your truck but if interested I will talk to them and can help get it to you, the mechanic that is taking them apart told me they were all under 2k hours

Those pictures make me sick @ knowing that all that green/tan iron went to the scrapper; instead of being utilized for truck repairs ot replacement parts. The only good part is maybe that this was all that was left after the serviceable parts were removed; the engines were salvaged too!

C cat is what's in the LMTV/FMTV correct? I prefer to keep it mechanical, personally.

Repower with an LDS motor, turn up the fuel a bit and play with boost pressures and you should be good. At least that way it is a bolt in repower. I'll be doing this soon myself.

LDS is nice. You still have a limit due to gears, but you can at least hold speed on hills better. Stopping is another issue.

 

[HETvet]

I like the idea of the displacement of the LDS engine. But I also like the responsiveness, in terms of power and modification, of the 6cta. Gearing is not much of an issue for me as I like the spicer 3035A trans and the low gearing of the top loader rockwell axles. Plenty of grunt down low, and a decent speed for back road driving.

The minimal horsepower deficit that the stock LDT has versus the stock LDS can be overcome by turning up the fuel.

 

[Jeepsinker]

Yes, but can the LDS not be turned up as well? All other things being equal, the LDT and LDS are not the same motor exactly. If they were there would be no need for two different numerical designations. At least the LDS isn't in danger of coming apart when it is producing the same power that the LDT strains to output.

 

[JasonS]

Why wouldn't it be prone to coming apart? It is prone to the same lower end failures and head gasket failures.

Not if you have a working brake system. I can lock up my 395s if I need to.

I'll agree with gimpyrobb... You should be able to lock them up (not that you'd want to)...

I was referring to failures associated with high exhaust temps. Yes they still are apparently subject to the other failures, although I haven't read about anyone throwing a rod from an LDS.

 

[gimpyrobb]

Anyone care to explain the single nozzle oil-squirter VS the dual? It does not look like they are very spread out on the dual.

Just wondering why.

How does the LDS avoid high exhaust temps?

I haven't looked inside of an LDS but my understanding is that the second nozzle was designed to keep the top ring groove cooled which enables the use of low additive oils common when the engine was designed. I have to wonder if this design feature is obviated with modern oils?

Give this thread a read. I fail to see how an lds is such a superior engine.

[Jeepsinker]

Stock LDT-134 horsepower, stock LDS-170 horsepower. Sure the fuel can be cranked up on the LDT to closely match LDS power output, but at the expense of higher exhaust gas temps because the fuel system and air intake and exhaust runners and ports coupled with small turbos were not meant to support the extra 40 horses that the LDS has in stock form. We could go into depth on it and converse on the matter for days I'm sure, but that was not the point of this thread. Simply another option for the OP.
