dodge intercoolers for gm 6.5??

[firetruck]

I know that intercoolers have been talked about a lot. Several people have mentioned fitting a dodge intercooler to our trucks. I searched for more than an hour but can't find the how to on this upgrade. can anyone help?

[deerefanatic]

There probably isn't a how to.... It's one of those deals where you just get started at it and fab and modify stuff as you go along.....

[Sasquatch]

I have looked at mine and don’t think there is enough room in the grill for a cooler. If you get it fabed up and make it work I’m sure lots of people would like to see how you did it.

That is what I was wondering. I read a post on here a year or so ago that said the dodge intercooler would fit right around the radiator. I can't see how, my rad takes up all the front end width. But if someone has done it please speak up!

[God prefers Diesels]

My brother Adam has a Cummins in his '88 Chevy. It is intercooled. I'm not sure how it's done, but it CAN be done...If he comes down from Denver before you get your project completed, I will take a multitude of pictures for you.

I'm sorry I can't tell you how to do it, but I know for damn sure it is possible.

[huntfishcamp]

Tell me where he lives and when i can run and take pictures. I live in Denver and would love to see that.

[God prefers Diesels]

just got back online. I'll get you his phone number. Honestly, I have no idea where he lives. I only drive through that hell hole on the way to this hell hole called Grand Junction.

But I'll get you guys hooked up.

when i upgraded my trans cooler with a 6.5-T engine oil cooler i made the bracket's just a bit long i had to notch a tiny square out of the plastic grill up under the hood to clear the bracket but there was enough room between the cooler n AC condenser to fit another engine oil sized cooler so i'm guessing if you got rid the AC condenser you could make it fit just fine. . .

My photos tho taken with a cell phone are too large :eek: or i would post them :mad:

i am in the process of gathering parts for my cummins swap and according to the research ive done you can fit a dodge ic in a chevy. Most people will run a dodge radiator with the swap but from what ive seen you can punch out holes for the ic tubes in the rad support and it will go around the radiator. The majority of trucks i have seen done are using the old wt grilles with the halogen lights for extra clearance, but im running the escalade clip, which gives you a little bit of extra room to play with.
Once i get going on this thing ill get some pics up of the intercooler in the gm rad support
By the way if anyones interested ill have a 100,000 mile 94 6.5 4l80e combo up for grabs in the coming months if theres any interest.
Im in NJ

[God prefers Diesels]

I can put one thing to rest now for sure...'94-'01 intercooler will NOT fit around chevy radiator. The intercooler is 41 inches in the clear, the rad is 41 1/2 inches wide. After I got my radiator out today, I tried it against the cooler, and yep!! it won't fit. Good thing I opted for a Dodge radiator. Another bad thing is the intercooler is wider than my headlights! I'll deal with that when I get to it.

PS My brother's '88 chevy cummins has a '93 intercooler.

[95suburb]

wut about a hood scoop and a top mount intercooler?

[God prefers Diesels]

Never thought about that, but DAMN that would be cool.

[M123KT-450]

Now that is an idea...

So why did GM not intercool these engines ?

Don't inter cooling increase power ?

Mike

[ZiGBlazer]

Would love to have that engine, I have a 73 chev that I built back when I was 18 and has been sitting around since I finished college, would be a great truck to convert to diesel, but I don't have the money.

[M123KT-450]

That 73 sounds like it needs a Cummins 12 valve 5.9L from a 95 to 97 FL70 or F650...

230hp n 660tq stock then add a GSK-3k add a some fuel n you got a 3200rpm snorting brute...

For few bucks n lil work you could be rolling a 73 Chevy with a 300hp n 750tq 3200rpm cummins kick'n tail n taking names...

But the stock commercial truck 5.9 power settings might be just enough.

190hp n 520tq.

210hp n 600tq.

230hp n 660tq.

So even stock the medium duty 12 valves had plenty of power if you wanted a cheap low cost solid reliable budget build.

[trukdoc]

...man what is it with you? you're quick to quote hp/tq #'s for cummins...what are you a shill for cummins they don't need your help...this is an excellent web site for 6.5t,sponsered by a company that services 6.5t's just because they can...and I for 1 am very gratful...I'm ase master cert. med/heavy trk.mobile diesel repair...this is all I've ever done...and I have NEVER shown the contempt you seem to have for 6.5s to any engine ever made...I'm out in central texas and these old ranchers never throw anything out...if we can get or have made parts they expect to run their diesel another 40yrs....I personally come to this site with a problem to be solved or to get a giggle cause some of these guys are pretty funny...but,alas I'm tired of you so this is the last time I will respond to your posts.....

[Garth J]

Thanks truckdoc I couldnt have said it better
Before id install a Cummins id put a D-max in it ..lets see what he has to say aobut that ...G

[M123KT-450]

Me being a GM fan I'd say go for it.

The first Gen D-max turned out some fine usable power.

300hp n 520tq.

I believe the current unit is pushing 365hp n 650tq so it to is a fine unit.

The 6.5 if you got a good runner is a fine engine.
I don't see it ever being transplant worthy tho my brother feels differently he bought a brand new crate 6.5-NA and a super charger kit and its going into his mint condition 1968 Chevy C50.

He claims its cheap enough to blow 1 a year or 1 every other year and still be cheaper then a commercail cummins swap...

Tho with the cummins he could gain himself a 7spd trans and gain an over drive.

Interesting to see how long its going to last running 3200rpm grossing 30K-Lbs.

I'm sure he has not intentions on re-gearing the truck.

I'm certain he'll continue to run it loaded heavy.

I love Duramax's. They are so smooth from idle on. If I ever get enough money I'd love to have one somewhere in the 01-04 range. It's the only computerized diesel I like, and man do I like them. I'd take a D-Max over my Cummins swap any day of the week. Even though I grew up with Fords, I realized less than a month ago that I am a Chevy man. The trucks are easy to see out of, the steering wheel doesn't cover up all the important gauges, the seats and belts are comfortable. They just got it all figured out, and now they have the best engine too. Of course I'd take a Powerstroke(even a 6.0L) over a Cummins Commonrail.

[M123KT-450]

Ford makes an ok Rig I don't mind them, I don't much care for Dodge trucks...

I have always went for the Chevy or GMC and used Ford as a plan B the few dodges I ran were only gotten as a last resort worst case deal.

1. GM.
2. Ford.
3. Dodge.

Normally how I rate them.

Tho this 6.5er is my second diesel pickup and my first Diesel GMC that didn't have 10 tires under it...I ran a few Generals with cummins diesels !

Mike

[Garth J]

I have a 2001 Chev Extended Cab short box D-max Allison I have Walts 4 inch exhaust and he had my ECM reflashed and I tell you when you put your foot in this truck you better be holding on..after the reflash on a test run the GPS shows 174 kilometers Per Hr.. That was one scarey ride It has almost 175,000 miles and runs like a clock Pulls my 8000 lb 5th wheel RV up the hills easily ...G

[Stumped]

I think they are all good now.If a person was into competition,hands down the Cummins will walk past them all(simply because they are cheap to modify).If I were pulling a med load and traveling,the Duramax is your best choice because of the independent ft susp and cab quality.If I were working it all day every day with large loads,the Dodge wins with almost 1" more stroke than the others,and a solid ft axle that wont change your alignment under load.Ford is great untill you modify($$) but quit making a diesel when they dropped the 7.3(opinion) the red 97 P/S I drove ran very good.The thing is with Ford is the terrible ft seats,which I think were made for 6'6" people.I think it all boils down to what a person is going to do with the truck.

[Garth J]

you are right is some ways but if you look at all the figures the dmax puts out the most horse and torque stock or modified and hill climbes or dynos dont lie...G

[M123KT-450]

Oh I bet ! A reflashed first Gen duramax is a beast !

There is an older gentleman in town with an 02 6.6 duramax in a 3500 regular can dually pickup.

Truck was tough looking he put 225/70R19.5s on polished alcoa wheels big beefy steal bumpers front n rear.

I chatted with him a while he's got the computer tuned(reflash I'm guessing), cone filter intake(cold air induction I'm guessing), and 4 inch stacks, and 4.56 axles (gear swap ?) and says it pulls amazingly.

He says it'll pull 15K-LBs like its not even there.

When he left the parking lot he squaked the tires!

I was very impressed !

...the 1st gen. dmax's ate cams and lifters...1st 2 in co. died in first 3 mths...1st ate cam...2nd broke lifter catastrophic failure...

[Stumped]

One should NEVER argue with the moderator,but...although the D/max does well at the truck pulls,she is a queen at best on the dyno.I spent almost the entire day in ft of the chassis dyno at Indy.Unless many,many thousands are spent on mods,they simply cannot compete with with the Cummins,even a mildly modded one.I am not saying that out of brand loyalty.We spent the weekend watching truck pulls,dyno and racing.The D/max did very well with the rpm range that a v-8 is capable of in the pulls.But on the dyno(like thats real world??) the Cummins is king on tq and h/power whether commonrail or not.The fords didnt even come close,untold #s dropped head gskts and valve train issues.You would watch the 6.0s fly apart almost every time..The D/maxs that were modded were spending enough $$ to build 4 Cummins engines.Structural integrity of the Cummins block was allowing massive boost #s,with heads not even fire ringed.I didnt take close note,but D/Max wasnt in the top 15 I believe.Those #s could be skewed however,as there were a lot of Cummins there compared to the D/Max.I noticed the dyno had a graph for ROR(rate of rise) avg#s under the peak #s were far higher on the Cummins.Well,time to get flamed.One last note,I would rather drive my brothers D/max anytime over my Cummins....and for brand loyalty..my goodness..been driving and likeing a 6.5 for many years and still do.

[M123KT-450]

The Cummins:

makes wild crazy power.

Performs well under heavy loads.

Holds speed very well tho not always the fastest getting there.

Its one of the most structurally sound diesels of the big 3.

Now the duramax is also a plenty powerful engine tho to add more power it dose take some work n money sure.

But stock the 6.6 turns out more then plenty power same as the 5.9s.

But the 5.9 just like the 6.5 is now obsolete and now the world of building 6.7L cummins diesels n 6.6 duramaxes are now at hand.

I can't really comment on the power stroke as I have never ran one or owned one.
The 5.9-CTD the 6.7-CTD and the 6.5-TD I have owned...

I'm very impressed with the 6.7CTD in my 08 sterling 5500 4x4 lots of power routinely tow 30-35K-lbs.

the 5.9CTD in my old 98.5 Ram3500 ran n performed beautifully towed 27-29K-lbs but after 250K miles it was replaced by the sterling.

AS for the 6.5er well its off to a rough start.

First year down 13 repairs later and its starting to have issues with cold starts again...

Temps dropped to 35*F truck started fine for a week temps warmed up to 40-46*F now it starts hard or starts stalls then spins over insteadly then fires back up stumbles but catches itself then runs great but high idles for 3-5min and runs great after ward not sure what that's about.

Prolly just a 6.5 being a 6.5.

Anywho its an issue I been fighting for a while all last winter now again this fall, never. Had this issue with any other brand of diesels tho...

hey garth, i thought Walt only sold 6.5 parts. How'd ya get 6.6 mods from him?

[Garth J]

shhhhhhhhhhhhhhh its a secret...

Sounds like some body has an inside line. . .

Bat phone perhaps LOL !

Surprises comming

[JD_countryboy]

Hopefully good surprises. and not an influx of retarded kids whom dont know crap, but talk alot of crap. dont own a vehicle but "momma n daddy" gave me this truck and all kindsa $$. And think they are gunna come on here and run us 6.5ers out. I do wish Walt good luck with any venture he takes. I'm sure glad he took this 6.5 venture and gave us a great place to gather and share ideas with.

[M123KT-450]

Oh i wouldn't worry yourself to much there is plenty of die hard 6.5 fans out there. . .:eek: :rolleyes: ;)

If this place turns into one of those douche bag Cummins forums where all they talk about are chips and sled pulling, I'm gonna be one upset dude. This place is like 'Cheers' to me. Everyone's nice and there isn't six pages of advertisements.

I guess if I can ever afford a Duramax of my own, at least a help resource will already be up and running. (a good one, anyways:cool: ) GPD.

[Garth J]

6.5's forever guys

[M123KT-450]

6.5's forever guys

says the guy with a Duramax. . .:rolleyes: only joshing ya ;)

i found my hard starting issue i think its battery related i'm down 550cca's from where it should be, looking into a set of 950cca's to replace my weak 800cca's as there only making 525cca each. . .

I have 1050 out of 1600cca's. . .:eek:

I loved my 6.5 but it just didnt have the muscle to pull my new trailer...G

[JD_countryboy]

Thanks for reassurin us that this great site will always be 6.5, at least this one, now ifn he would expand to dmaxs, it be nice to have as great a site as this for those too, if i owned one. I browsed some of the other forums, and forget them. Too much crap. I enjoy this site. Thanks Garth for keepin it clean, and Walt for hostin us.

[Garth J]

Thanks for the vote of confidence I try to do my best. I check the forum 3 or 4 times a day being retired helps.
When im away camping like tomorrow till wed. I take my laptop and have a little gadget that plugs in the side and if I can get cell service I can check the forum.
You guys are the best of any forum ive looked at all gentlemen, and Walt appreciates that too.
I was at his shop early September and was impressed at how professional it is
he works hard to keep everyone happy, all in all he is a great guy just trying to help us all have happy trucks...Garth

[sommerfamilyfarm]

I am NOT sending anyone any where else just thought you might want to see what the kit looks like for 6.5. This is the one I put on mine.

[turbowtie]

putting intercooler on a 6.5 isnt really worth the hassle in my opinion. the cummins and international engines in fords and dodges are low compression high boost engines the routinely make 20-35 psi and have ususally about 16 to 1 compression. a 6.5 and 6.2 engine should rarely be pushed over the 15 psi mark because it builds "correct me if i am wrong" 19.5 to 1 and 21 to compression static you really aren't superheating the air worth an intercooler at 10 or 12 psi if you really have to have a cooler intake charge go with water methanol injection. the mixture the use for that is extraordinarily close to the cheap "blue water" windshield washer fluid you see at gas stations

[God prefers Diesels]

I agree with that. But for anyone that wants to know anyways, if you have a Silverado front end, you're stuck with the 93 Dodge intercooler. I don't like it, because it's about as big as an A/C condensor. I am adamant on fitting my 2nd gen intercooler, so at the sacrifice of good looks, I just bought a W/T grill and rad support(everything between the fenders) so the intercooler will fit. And even then it's so tight I'll have to do some bracket mods. Luckily the front end I bought is in excellent condition.
