Best mods for 1993 towing truck!!

I have a 1993 d350 dually thats getting an engine overhaul, 6x18's, Denny t II
Fuel pin, 3200 rmp spring, 4' turbo back exhaust, tweak pump, stainlessteel manifolds, fluidampr, twin horn intake (ram aire) , S&B air intake. The question is what is the best turbo for such mods and any advice on the mods I made or to be done for a towin/work truck??

Thanks for your reply; Yes, i looked into it, but looking for something fancier!! I forgot that I also put a 14 mm rotory head for that ve pump, so lots of fuel going thru it!! They recommended me a 62/71/12 phatshaft, but looking for more advice.

That's an insane amount of fuel for a work truck, twins are probably your only choice.

How well is your trans built? How heavy are the loads it will be pulling? I found out real quick that the 518 isn't happy pulling heavy with a turned up motor. Egts could also be an issue depending on the terrain you run.
I ended up dialing mine back till I can get a better (47rh or manual) trans in mine.

Yeah if you want lots of power and still be towable you have to have twins!

The transmission I m getting is the same 518 but from monster transmissions, I wanted to upgrade to nv4500 but the conversion and everything Im putting in was going to be to much time and there are not so many reliable mecanics on this part of the world. Im gonna pull close to 9k o more!! I live in south texas so not many hills down here. Twins?? $$ I didnt want to but what would you guys recommend???

those injectors seem awful big for a work/towing truck, your going to need lots of air to keep from just perforating a piston or two. Twins are probably your best bet or just go back to stock/mild because 9k isnt all that heavy and a stock truck will move it just might be a little slow.

Well stock is not an option, so what twin set up could work best for towing???
