I'm looking to find some diesel intercoolers for my project talon. All of the popular "riceburner" intercoolers are upwards of 600$ just for the cooler and no pipes. I have been reading about people putting powerstroke intercoolers on turbo minivans, and it got me interested.

Has anyone on here ever tested any mainstream diesel intercoolers (1st gen, 2nd gen, 3rd gen, powerstroke, duramax) for efficiency, pressure drop, and airflow in cfm? I'm looking for an intercooler that will flow/cool enough air to support 450-500 horsepower from a 2.0L engine.

 

I am pretty sure an intercooler out of our Rams would work just fine for you. I believe they can hold 60 psi of boost pressure. A few have failed before getting to 60 and there are others that have gone past 80 PSI. As far as air flow, there are guys running twin turbos and the intercooler isn't holdin them back. If you have ever seen one of our intercoolers, they are quite large. Maybe someone else can chime in with the specs.

 

I would agree. Most rice burners don't run the kind of boost numbers after they are modified that our trucks run stock. I don't think that efficiency would be a problem but the physical size may be.

 

Cool. I figured the efficiency of the intercooler would be more than I need, but with only a 2" thick core, I was worried about how much the core would actually flow. I haven't been able to find a dodge intercooler for very cheap (i'm a cheapass), but I found a powerstroke cooler for cheap and I was gonna cut it down to where it was only 14" tall and make some endtanks for it. I'm gonna be running a holset h1c at 20 psi.

 

20 psi is what most diesels produce stock. Should be no problem if you go with an intercooler out of a diesel.

 

Well my assumption is that the dodge intercoolers flow enough air at 5.9 litres and up to 400+ HP so why wouldn't it flow enough for a 2 litre????

 

I agree completely. (oh and the Talon being a Chrysler isn't rice and may run low 30s for pressure on a modified one, and are 11psi stock.) I don't think it is anywhere close to fitting in our DSMs. If I recall correctly the height of most FMICs are in the range of 18-20" tall. The stock intercooler is very efficient but not big enough, unless you have a way to take the CTD I/C and make it smaller I'd go with a Starion FMIC over the CTD I/C.

 

oh the starion fmic is junk. It's just barely better than the stock one. I've already had one of those, and I heatsoaked it at 14 psi on the stock 14B. I rebuilt my motor using the stock 6 bolt big rods and 2G 8.3:1 compression pistons, so I plan on making 500 horsepower before it blows up. I'm going with a holset h1C so i'm gonna need something that will cool it off better than a starion fmic!

I was measuring, and a cummins intercooler is really too wide for me. A powerstroke intercooler is about 35" wide, which is as big as i can really go. I was planning on cutting the core down to where it will be about 14-15" tall so it will fit.

What all have you done to your talon?

 

You better have the head o ringed and some arp studs with all that boost

 

Yea I know the Starion isn't really that good but it does fit. I was lucky with my setup, it is the 6bolt motor with 4bolt rear.

I haven't really done anything wild to it as I realized about a year or two ago that I'd rather have a diesel to mod like that. Anyway it has a 3" intake, 2.5" UIC, 3kgt VR4 fuel pump (rewired), SAFC (off of MAP sensor), 2G manifold, the whole turbo setup is fully ported, MBC, Autometer EGT (TRE K-type probe) & boost gauge, Aiwa mp3 player with PPI amp, and a JL 12W0.

I'm not sure when the ARPs are required but I'd imagine anything in mid 20s could use them.

 

Nice.. I used to have a '92 6 bolt/4bolt that I sold to a friend who ended up parting it outl

I'm fully built for high boost. I have a cometic megal HG with ARP studs torqued to 80 ft/lbs, 1mm OS SS valves, and a pair of web cams street grind. I'm still using my puny 14B and stock sidemount, so once I bolt a holset on, i'm ready to hold on for dear life.


Anyways, to bring this back up, how is the performance on a chevy duramax diesel intercooler from an '02 truck???

 

I'd spring for a deal like this over modifying a huge intercooler to work in a small spot.

I'm not sure who makes that core. Most of the good FMICs seem to be quite thick which I don't believe the truck ones really are, they get their size by surface area more than depth like we need.

 

welll, if I could afford that, I wouldn't be on here asking about diesel intercoolers..

A guy here in town offered me a perfect duramax intercooler for 50$, so I think i'm gonna get it regardless. I have a tig welder so I can weld up some good endtanks once I cut it down to size.

 

I'd say that at that price you'd be able to resell it and make money off of it if you didn't want to use it. You have your own TIG welder but can't afford a FMIC?

 

right... i'm paying for my college education right now... need i say more?

I got the tig a year and a half ago when I worked at a cylinder head shop. I used to do freelance headwork for people, and I have all of the machines needed for it in my garage. (surdi pressure tester, surdi valve seat cutter, vat, shot machine, Benson stone angle valve grinder, etc, etc)

That's the only reason I'm building up this talon is to prove what can be accomplished on a very tight budget. With everything, I hope to be at 400 whp and low 12 second 1/4 mile times with 2000$ spent including buying the car.
