Hi, am new to the board and need some advice. Just finishing up a 75 Power Wagon project, looking forward to the next one, which will be my first diesel project. Always been a mopar man, but want some advice on building a diesel. Thinking that I want to swap a 12 valve into an old four door power wagon. Want to run a VE pumped 12 valve and an NV4500, at around 300 to 350 horses and about 700 to 750 ft/lb. The truck will be used as daily driver that I can tow with (IE EGT wont get to hot on long passes) I live near 4,000 ft and regularly go higher. Would not mind some smoke when starting out, but would like it to be reasonable, don’t want to kill mileage. Does this sound like a reasonable expectation for power? How can I make this kind of power?

Was thinking that I would start with a non IC motor, add a power stroke IC, open up the exhaust, say a 4” single split to 4” duals exiting behind the tires. But where do I go from there, injectors, turbo, fuel pin, pump tuning etc, please be specific. Don’t mind scrounging used parts and heavy fabrication, its actually preferred. Project is still in the planning stages, but any help would be appreciated. Really like the simplicity of old trucks and think a diesel would be good for my next project, and as always want to keep it mopar/cummins. Thanks guys, Buck Wescott

a non-ic motor with a better turbo and some pump tweaking should do just what you want. there's tons of info here on how to do all that.

 

Thanks Bud, do you think a turbo setup off a second gen would get me what im looking for, or at least close? Have been slowly building up my diesel knowledge, have been searching, reading and looking around for a while, all of what i have learned has come from web forums, no hands on yet. Thanks for the help.

 

Working on some bigger injectors and nozzles for the 9mm injectors. should be ready in 4-6 weeks.

 

The second gen turbo would be a good upgrade, they have a smaller turbine side so they will spool faster, and a larger compressor side for more boost. You can also get a smaller turbine housing for the stock turbo, will probably be a little cheaper. The 92 and 93 first gens are already intercooled though, I can't offer any comparison over the powerstroke intercooler vs. the cummins as far as flow, but may be easier to start with. Good luck, post some pics!

 

Thanks, had read that the first gen IC was a bit down on flow when compared to a PS IC, so was thinking a PS IC or Second Gen IC combined with a non IC motor (bigger injectors factory) would be a good place to start, but realizing that Ill probably end up upgrading Injectors anyways. Will try and post some pics of my gas 75, but havent even started acquiring parts for the next project yet.
