Ford Excursion 12v Cummins, need guidance!

I'm not saying that it can't be done, but modding an intercooler requires more knowledge than most "shade tree" mechanics possess.

Not alot of folks can weld aluminium, and making new ends caps will require some fab time and alot of welding.

You would then need to pressure test the intercooler for leaks, and again, not alot of people can do this either.

Hello Political Biker, Im pretty sure the ford Excursion was based off the 3/4 ton.
If i were you i would sell the excursion and go buy a ford truck or dodge 1 ton.  

call russ at maximum diesel in hemet, Ca. i was in his shop last night and he had a 12v cummins in a lifted excursion that he did a while back. it looks pretty good, almost like it belongs there.  jd  

Thanks for the reply. I looked around for this notorious Excursion you mentioned. As well as the shop. Do you have a URL you can give me that links me to their shop? I will be sure to follow up with you if I find it.

Thanks again,

Kris,

Thanks again for the help. I agree that replacing the radiator is probably the best idea. Not to mention I am not the best welder. Let alone tig welder. Aluminum is a pain to deal with. All of my experience is based off of my cycling career. Our Columbus aluminum tubing used in some of our frames was very difficult to work with. Hence our move to different carbons. Let it be 1K, 3K, 6K, 12K, UD, OCLV, or even CNT carbon, it was still easier to deal with. Anyway, got off subject, thanks again, and I will be replacing, not modifying.

There is a artical at this sight you should read on P-pumps.
I have been thinking about the Dodge intercooler & this comment,  "For the intercooler, it needs to be 100% aluminium because some of the stock intercoolers on the Dodge have plastic end pieces which totally suck and have a tendancy to pop off or simply break.  Most folks that want the added dependability will fix this simply by replacing the stock unit.  Run your boost too high and they pop right off, and dependable goes right out the window.  And of course running compound turbos will pop those end pieces in no time flat."
Why couldn't you cut the plastic conections off & wield on alumminum ends? This should save a bunch of cash sence thier are so many around.
I have also been thinking about the Turbo-lag, if you got with An after market turbo that uses alittle better barrings, but one that would work as twin set up so when you went that directon you are half way there, this would help. Also you can turn up the P-pump & put in a 3200 or a 4000rpm govurner spring. If this sounds good to you besure to read the artical @ the link to "Blacksmoken.com". There is some good info about putting in 60psi valve springs & not using stock fuel pumps. Oh another thing I came across is the 5R110 trans. out of a 03 to 06 or 07 ford supper duty, I am not sure how long they used them, but they are a party though trans the best part is you don't have to worry about building them up. They also came with a PTO option, which could come in handy, you never know. I don't realy know how it would hold up behind 850 horses,but it is worth looking in to. The one I found had 83,000ml. on it but they only wanted $900.00 for it. The transfercase was another $650.00-make sure you get the manuel case. For adapters & wiring Ford cummins.com can help. Any way good luck & Dream BIGER!!!!!LOL  

Tim,

Thank you for the link, it was very insightful! Yes, I am planning on doing a twin-turbo setup done by BD-diesel performance for simplicity and reliability. I am not sure how much boost it is capable of, but I am sure that you can regulate how much boost it does produce. My guess is that I will not be running more then 50 PSI to make my HP numbers. If I find I need more, and the turbos can make more, then I will definitely replace the valve springs. If I have more money/time I would consider a super/turbocharged setup. But, that is a whole other story, interesting as it may be.  I will do my research on the P7100 pump to make sure everything works well together reliably. I noted that the maximum injector size on the link you provided was 370HP marine injectors. I was planning on 350HP marine injectors. But, now I know better, I might consider something smaller. Regarding the transmission, on a previous reply, MarineOne (aka Kris) suggested the projected price on a built 47RE transmission would be about $6,000. I think that is a bit pessimistic, but better safe then sorry. I also found that an 6 speed Allison transmission with a stand alone computer might be a more pricey option, but an option to consider. The stand alone computer will allow you to choose individual gears 1-6 as well as converter lockout in any of the gears. I think I will cough up the $6,000+ to do this on my build. The transmission plates can be provided by Destroked.com. Really cool site, check em out.

Hello Political Biker, Im pretty sure the ford Excursion was based off the 3/4 ton.

Jomax, I am pretty sure that its based of the 1-ton. A buddy of mine has a F-350 SRW short-bed and the two trucks are virtually identical. Frame, suspension, and engine. All the same. Also, lets say I did make the mistake of it being a 3/4 ton chassis, the only real difference between the 3/4 and 1 tons is stiffer Coils, leaf-springs, and sway bars. Axles, engine, and frame are the same. It'll work, no worries. But, again, thanks for the concerns! I am bound to mess up.

Thanks JD, doesn't look like they have a website, So I guess I will just have to give them a call. Do you know them personally?

Hey kyle, I met russ in july at the barona drag races. He has a pretty fast 12v in a 94 dodge. We started talking and i told him about a friend of mine that has a 98.5 dodge that needed the engine rebuilt. So i took him the engine, and he rebuilt it. Russ is very good at what he does. He showed me the excursion he stuck the 12v in and it was a nice conversion. He does quality work, and his shop is busy all the time, so if you get a chance to call him, tell him i gave you his # and what you are trying to do. There's no better way to get information than from somebody who has already done the job. good luck.    jd
