Hey i have been working on trucks ever sence my dad handed me tools and told me to fix it my self"heres the tools ul need git after it" now that i got that down and my new 91 12v cummins 1st generation i wanna learn what i should start with first performence wise? I wanted to add as much power as a stock clutch could hadle just fine then up grade to a 350h 800 tq clutch then go from there! is that whats best or where sould i start? i played with my ve fuel pump today but im not really all to sure what i can do with it and whats to much for a stock truck and that pump? i got it to throw a lil more smoke today i was pretty pumped to push the gas siting there and see a better cloud come out! made my day what should i do now...
thanks for all the help

 

Gauges first. Get a pyro. There are a lot of articles if you search around. Look deep into your wallet and see how fast you want to go.

 

im not to worryied about speed.... my maine goal is to be able to hook up to anything and pull it all day! i work and live in cattle country so i pull a 28 foot trailer alot that we have full of cattle. for right now i dont plan on more than 350h and around 800tq. then later on add on. but thanks i will git set up with gauges

 

if you use it to work all day in, id leave it stock. ever since i messed with mine for the first time now im messing with it constantly. not to mention if you haul cattle, i know for a fact they dont like black smoke in their faces

 

its still up in the air but then again i still have another truck i can use to pull haha. maybe it wont roll it out all that much, no take that back if ima play with it i wont alot of it! we will see im geting my pay check this friday. i just wanna have it all planed out just in case this is what i wanna do.........thinkking it is and i wanna do it right the first time!

 

smoke is cool and all for a couple days but trust me it gets real old real fast. all it is wasted fuel and destroys your fuel economy. and it also gets expensive fast you do one or two upgrades, then something else either breaks or doesnt work right. and next thing you know, your repairing something else every weekend

 

Yeah he is not lying I have a 91.5 12v about a month ago I maxed out the fuel pump. Since then I have had to replace the lift pump.And my injectors.And they only had 130,000 miles on them. Is your truck intercooled? If it is a here are some good little upgrades for you. First would be some Dynomite Diesel 80 horsepower injectors for only about 700 bucks.Then Dynomite Diesel Power Pin which will give you 25-40 more horsepower for right around 200 bucks.

 

yeah i have the same truck as you aaron. 91 but not sure if its 91 or later that year a 91.5 how can i figure that out? and yeah i have looked into the old smokey power pin and injectors but i was thinking 40 because i didnt want to mess any thing else that is stick up i figured do it right the first time so i didnt have any major problems. plus i also looked at that 3200 rpm spring. so i should go 80horse if im intercooled

all i have done with the pump is turn the smoke screw a bit more more fuel bout 2.5 turns. waiting for my bad to help with turning up the rest and more upgraded parts

yes intercooled

 

I would go with an M&h fuel pin that way you can get one thats better made for pulling. And since you are pullin I would look into upgradin that turbo before you get too fuel happy. I have a 93 cummins thats got the stock turbo it spools like a turd. The quicker you can spool the better you will take off with a load.

 

hmm aright never heard of that brand tell just now and im looking at them now...m1-m5 and what type of turbos do you suggest?
