Hi,
I am new to the site and am looking to get enough power and torque to pull a 5th wheel trailer with my 91 w250. Its all stock so i have a blank slate to work with. I am hoping to find someone with the answers on how to get what i am looking for. I think I found the place if someone is willing to offer some advice.

it depends on what you want, and what you have to start. is it intercooled? how much do you want? there are things you can do with just air and exhaust upgrades and some pump mods that will get you more power. you need gauges first so you know what you are doing to start with. if you go with turbo and injectors you'll need more air and bigger exhaust anyway, plus a clutch or convertor, and the list goes on...

how much HP are you trying to get to? an hx35 will give faster spool up and is waste gated, it will handle up to 300HP, if you want to go bigger than that get a 35/40 hybrid or a small s300.

i guess you have to ask the question you want an answer to? an hx-35 is not really known to be much of an upgrade. if you do much for fueling you'll out grow it fast. as for injectors, the sky is the limit! do your research and find what injectors will do what you want. they say around 300hp is the sweet spot for towing with these 1st gen trucks.

The most important question is when was your truck made? If, like mine, yours is an early '91 then it has big injectors and no intercooler. It can be turned up quite easily but will generate high exhaust temps. If It is a late production '91 then it can be turned up some, and can handle the resulting heat better.

IC'd trucks usually need bigger injectors to benefit much from pump adjustments. I would stay away from PODs and try one of the Bosch sets.

Thank you guys so much for the help. Mine is inter cooled and i would like to get inthe 300-350 hp range i think that will be enough, the newer trucks have that much and they do fine on the highway.:yourock:

They have a lot bigger IC also. Trying to hit 350 HP and tow is going to take some work on a 1st gen.
