thats a good questions. everytime i call cummins with questions they dont know what to do. I told several different cummins dealers what i was doing and all i could get was hummsss and ummsss... then it would always be "You need to decide on what CPL you are going to build the motor to" and i...

look at post #72 and you can see where the oil lines hooks into the top of the oil cooler on the passenger side of the truck on the front of the engine.

The oil pressurenline will come out of the top of the oil cooler. There should be an oil analsis port there that you tap into. It's where we have all tapped into. There is pictures of in this thread. The return line is a big hole in the side of the engine under the exhaust manifold. You will...

they have been doing it for years. cummins made a kit to do it. it says it in the thread not sure what post it is but you can get all the literature from cummins.

It was a very simple upgrade. I believe I would install the turbo before i would go to all the trouble of doing an engine swap. But if I was going to swap engines I would swap with something a little bigger than whats in a m939 series truck.

the M915, M916, M920 have the 400 big cam engine and have turbo. But i think i am correct in saying that the rest still have the NHC250 wich are none turbo

Here is what I have put together and been running it for 2500 miles. Did anyone block off the hole where it shows vaccum to tell if the air filter was stopped up or block off the cold start pump? I did not and was wondring if this would matter. Was also thinking about useing the line that was...

nice job 1943ht.... that is prety much what i did with my cross over but for some reason i didn't have enough room to do that. and it looks like my manifold and turbo and yours is the same. just wondering how much room you actually have between the hood and turbo side of your cross over pipe?

I am running 395's on mine and I think I can run 63 at top speed.

I think I am going to add a bigger fuel pump to my truck. Mine is leaking at the throttle shaft and was talking to a guy and he said that I could fix the leak but I would be better to put a different pump one that would allow for the compensation of the turbo. I will more than likely go with...

ebay is also a good place to purchase the silicone boots. they are cheaper on there than anywhere else i have seen.

my oil supply line hooks on the fitting right on top of the oil cooler... there was a little valve there on mine with a short peice of hose on it. fir the truck up and open the valve to make sure yours is pumping oile good. just be sure to stick the little hose in a bottle or there will be oil...

I'm not looking for constant black smoke but smoke when the turbo is spooling up is something that i have seen out of almost every diesel truck.

i am not sure how much boost i am pushing for the simple fact that i havent goten a boost gauge yet. i installed my 395's today and the egt went back up. it stays about 850 to 900 degrees going down the road. I still dont get any black smoke. as for the head gasket i think they will hold up to...

I finally got around to turning up the fuel on my 818. i instaled a #10 button and it helped it out alot. The Egts came down when i did this. Before i was running 900 degrees runing down the road 5 gear 2000rpms and now i am at 700 degrees at the same gear and rpms. the truck runs alot better...

I mean the exhaust temp. Just wondering if anybody has been able to hit 1200 degrees or more after they install a turbo. I have installed mine and it is runing and driving now. I am going to start turning the fuel up as soon as I get some of the buttons. I can get it to 1100 now with just bob...

has any body been able to get their exhaust to hot with the turbo on there. a guy told me that use to do this all the time that the pump and the injectors wouldn't let me get the truck to hot. just wondering what you all think?

will 3/4 of an inch be enough for the boot to clamp to? and if my pipe is 2 inches or more it will be in the hood if i do that i think

there is only 2 inches from the top of the turbo to the rib i dont know of one that will clear

here are a couple pictures... one is of my 90degree elbow coming off the exhaust side of the turbo and the other is of how close the top of the turbo is to the hood...
