    Duramax intercooler and radiator conversion

    A 2nd Gen Cummins CAC fits in the core support. I had to remove the AC condenser though.

    HE351VE with functional VGT on 1997 6.5L

    There are a few attached to his last post. I ditched my AC system, it didn't work anyway.

    HE351VE with functional VGT on 1997 6.5L

    At least 2.5", maybe 3"?

    HE351VE with functional VGT on 1997 6.5L

    Possibly, but then I would have to modify the inner fender more. I was thinking cut it, angle it up 45 degrees toward the turbo, and fill in the corner back in. By me doing it, I mean someone who can weld lol.

    HE351VE with functional VGT on 1997 6.5L

    The shroud isn't sealed to the Cummins radiator very well, that could be a lot of the problem as well.

    HE351VE with functional VGT on 1997 6.5L

    So the Cummins radiator does not have an internal trans cooler, so I am running a larger than stock external only cooler. It is the same size as the stock oil cooler for reference. The situations where temps were uncontrollable were while towing either a loaded hay trailer or camp trailer, 10...

    HE351VE with functional VGT on 1997 6.5L

    They are, but there is the internal transmission cooler right where the outlet would need to be moved to. I plan on utilizing that because of other low speed transmission temperature issues I am having as well. Also, I would rather hack up the used and un-warrantied CAC than a brand new radiator.

    HE351VE with functional VGT on 1997 6.5L

    It was used when I got it, so I'm thinking it was removed because it was gummed up. It doesn't cool as well as I think it should. I don't want to buy a new Cummins radiator just void the warranty by drilling and tapping holes in the end tank for steam and heater core ports. So I'm going back to...

    HE351VE with functional VGT on 1997 6.5L

    Yes, I would have to run coolant in it because of the climate here in UT. I like the simplicity of the A2A, and it works very well. The new radiator is a Champion aluminum one, similar to the stock GM radiator. The problem is that the intercooler inlet interferes with the radiator outlet, which...

    HE351VE with functional VGT on 1997 6.5L

    New heads, head gaskets, and studs all installed, runs great again. I have a GM aluminum radiator ready to go in to replace the used Cummins cooler. The decision now is to either modify the Cummins CAC to clear the radiator outlet, or switch to an air to water CAC. I have other parts in the...

    What did you do with your GMT400 today...or yesterday....

    I picked up one of the VCX Nano interface modules from Amazon so I could have full Tech2 functionality. Ran a TDC relearn just for giggles to test it and my pump timing was way off. I think the shop that replaced the heads knocked the pump off and didn't fix it. Got the TDCO back down to -1.26...

    What did you do with your GMT400 today...or yesterday....

    I knew you meant coolant for the turbo, I guess I just missed it in my reply. The HE351VE has both oil and coolant feeds - oil to lubricate the turbine shaft, and coolant to cool the cartridge and VGT actuator. I put the coolant feed and return in line with the heater core hose so it was pretty...

    What did you do with your GMT400 today...or yesterday....

    Going to follow this video for the rebuild - . I ordered the larger compressor wheel/housing and basic rebuild kit from Prosource Diesel a few weeks ago so I just need to get the turbo off the engine. My only concern is going to be getting the turbine assembly balanced with the new compressor...

    What did you do with your GMT400 today...or yesterday....

    Can you just stick the straw up in the latch mechanism and spray from there, or should you take it out and be more precise? The lock mechanism on my passenger door is gummed up or binding, I have to press the lock button multiple times to get it to fully engage the lock.

    What did you do with your GMT400 today...or yesterday....

    I have an HE351VE that is getting a 63mm compressor wheel when I do the pump. It leaks oil pretty bad so needs a rebuild anyway. May be switching over to air to water CAC as well.

    Special order from Quadstar. It runs $2500 plus cost for updating the tune. Have to speak with John to get a hold of one.

    What did you do with your GMT400 today...or yesterday....

    Technical details weren't divulged. He would only say his flow tester topped out at 140 cc and it was still going.

    What did you do with your GMT400 today...or yesterday....

    It flows up to 90% more fuel than a stock DS4. This is the pump that is on the truck that ran 472 HP. John set me up with a 390 HP tune because I'm missing the marine injectors to get more out of the pump.

    I have an injection pump to do as well. Going for a bit of an upgrade though...
