I am in the process of building a diesel street rod. I have a donor 92 2WD Dodge pickup. I am not sure if the old Gen 1 and 518 transmission is the best way to go. I will be stepping up the engine, once the chassis and body are completed.

If you were starting from scratch, and are interested in building a fire breathing street/strip diesel monster. What engine base and automatic would you choose?? .

The new vehicle will be a chopped top, stretched, channeled and sectioned M37 Dodge Power Wagon. And no, we are not cutting up a classic. US Body source is providing the fiberglass (rust free) body.

Well, welcome to the board. You should be able to find all the info you would want here on building a hotrod diesel.

IMO, if you want to build a no-guts, no glory diesel hotrod, I would suggest a P7100 pumped 12v CTD. 700 hp and 1400 ft/lbs is easily achievable on #2 only with a ported and reworked head with o-rings and studs, twins, a professionally reworked P7100, some BIG injectors and a done 47RE with billet everything and a stand-alone PCM. 800 hp is possible with some tweaking from a pro and maybe some water/meth injection.

Thanks for the quick response. Is there any reason not to use my 92 rotary pumped 12v as a core, with conversion to the P7100 pump?

CTD NUT

I'm not sure what you mean by "core". the VE and P7100 are completely different pumps with no interchangable parts, but you can convert to a P7100. You can get some decent power out of the VE but you just can't touch the ulimate power levels that the P7100 is capable of.

clarkoh

I meant the engine block, head, crank, etc. For rebuilding and modification. Or is there a better choice for strength or ultimate performance. My 92 has 213,000. No problems, just broken in alittle.

CTD is saying you can use your existing enging and change from the rotary pump to the P7100.

Who makes a stand alone PCM? Since this thing will be a 40 something model, emissions are not going to be checked. Hopefully, when the hammer is not all the way down, the black smoke will not be too thick!

Any suggestions on sources of 47RE parts to "bullett proof" the transmission?

Thanks again and in advance.

Emissions testing is done by the year of the vehicle or by the year of the engine, whichever is newer. So if you have a 37 split window coupe with a '05 LS6, it has to meet the emission requirements of 2005. I know because I had a 1966 dodge power wagon with a supercharged 360 out of a 99 ram and got nailed for emissions in Illinois when I was going to school. They didnt give me a whole lot of grief because the truck is registered in Wisconsin but they did tell me that a vehicle has to meet the requirements of the 99 model year.

So far, in North Carolina, only the gas burners in certain higher populated counties get the emissions check. Cars and gas trucks pay $29 for their annual inspection. Us diesel owners get away with the $9 check of safety items!! But, excessive black smoke might get the DOT cops attention.

Start looking into georand bros trannys to build that 47re.

and

Start reading all of the 1st&2nd gen performance threads.

welcome aboard

keep us up to date on this project it sounds like a one

clarkoh

How can I reach georand bros transmission?

How much of the 47RE is electrically controlled? Could it be controlled manually with switches? I agree with getting rid of the 518, especially since I need a lock up converter for the best performance.

In switching to the P7100 pump, will I need the computer from a 2nd gen truck? Or will the one in my 92 donor be compatible? Except for the lock up function?

Dave Goerend can answer your tranny related questions.

clarkoh

Thanks. The email is in the mail....
It looks like Dave has the expertise to control the torque and the facilites to test his stuff.

clarkoh

It looks as if I will be converting over to the Gen2 P7100 injector pump and the 47re transmission. Any other words of advise?

I do plan on using the wiring harness from my 92, at least in part for the hot rod. Any problems with compatablity between gen 2 pump and trans and gen 1 wiring? I already know I need a controller/ switch for the lock-up converter.

A 47rh out of a 94/95 would probably be easier to use for you since they arent as electronic as the 47re, but are a lot the same internally. The only wiring you need for a 12v with a P7100 is for the fuel shutoff solenoid. Thats the only thing needed for it to run So basically get the pump and all working good/mounted, and heck if worse comes to worse buy a lawnmower choke cable to work the solenoid with from in the cab. Shouldnt be much problem after you get the pump mounted up. Good luck, and keep us posted!
