hey guys,

I just purchased a 1990 w250 diesel, 4x4 long bed, automatic (?727 its a 3speed) with 123k on the clock. I must say I know nothing about diesel's. It runs sweet and was used by an 80 year old guy as a plow truck. It is 100% stock. It needs an exhaust and I was considering the Flomax 3.5inch setup from Summit, also maybe a K+N filter, what would you all reccomend?? I have also looked into the bully dog fuel pin upgrade, they claim 40hp, ist it worth it? Do I need to do anything else with the fuel pin to ensure the truck will run safely? Would the bully dog fuel injectors be better the the fuel pin? Are the any good instructions on how to adjust the VE (??) pump for more power.

What should I do as regular maintenance to this thing, I was thinking service the trans with filter and fluid, the rearend leaks so I need to change the seal and pumpkin gasket.

Any help would be awesome, I cant wait to start toying around with this thing to see how much of a beast it is.
Thanks in advance
Nick

 

Welcome to DTR! Yes, they can be a real beast once you start down the slippery slope. But the stock answer to your questions usually revolve around gauges as the first adviseable mod. Boost, pyro and in you're case tranny temp to start with. That way, you know where you're at initially so you can monitor things as you start to add fuel and avoid/diagnose problems with high EGT and other issues that crop up.

 

thanks, when installing the EGT gauge does the turbo have to be removed? Is there any pics or instructions for doing this and the Boost gauge?

 

If I still lived in Brunswick I would tell you to drive down and I would help you crank out some free power.

You dont have to remove the turbo, but you do want to use grease on the drill bit and tap though, and maybe a shop vack to suck out any shavings that may drop in.

 

I will need to get an EGT, I read somewhere you can mount a boost gauge off the back of the head, any further details on doing this?
What is the best exhaust to buy?? I was looking at the Flomaster 3.5 downpipe back setup from summit....

 

i suggest jaerry jardine form ebay, he has an ebay store they sell a good 3.5 in ch downpiep to a full 4 inch all the way for about 280$$ a great deal, the easyest way to find him is type in cummins exhaust, then find any make product by him and click his name, then his page will come up, good luck!

 

I just ordered my Jardine Exaust, I was going to order it a month ago but thy said they were having fit problems with the 1st gen 4x4 auto. I got a call from the last week and they got a truck to fit test and got all bug worked out. I haven't recieved it yet but I must say that there responce and promt answers are great. It's going to cost $290 shipped and thats the best deal I could find. Do a serch on Ebay for pinnical performance 4" dodge exaust. As far as your guage and perf. ? click on the "STICKY" at the top of the page and almost all your fix and upgrade ?'s can be answered there.

Thanks for all the replies. If I was to get a fuel pin, should I grind mine, buy the smokey one or the BD one from Jegs??

 

ol smokey is making the real deal himself again now i am expecting mine shortly i would rather have the original than some knock off
pm me your email and i will relay it to him -Eric

 

So I will get the Jardin exhaust, the smokey pin, k+N filter, where can I get the 3200rpm spring?? Does any one know the price of the smokey pin?? Is there anything else I should plan on getting??

 

Many or most(?) would recommend the BHAF instead of the K&N. The 3200 spring should be available from any Bosch dealer. A search should give you the part number.

 

Excuse my ignorance, what is BHAF??

Very large dry element paper filter. Works very well with an Outerwears cover to keep the moisture and the big chunks out. Search BHAF for part numbers.
