Installimg a 1999 24v cummins in a 1978 f350 I need advice on getting the turbo to clear the heater box

 

Not sure on the '78, but sometimes you can flip the exhaust manifold and clock the turbo, which will set the turbo up higher and closer to the motor...which is what I did in my '93 12valve Fummins...



Or, if I recall correctly, you can run a Commonrail manifold which will put the turbo back and down along the side of the block, kind of like one of these (only this one is off an "industrial" 12 valve out of a CF8000 Ford cabover truck)...



You'll likely need this one, if you want to go that route...

 

Thank you for the information and the pics I will try fliping it first

 

Heres what I did to mine.. I recessed the bottom section of the cover and the farther forward the engine sits the more it will clear it.Keep in mind,my cummins is a 12valve.






And if you are running AC, Then this is what I had to do to clear the Ac compressor





Eventually Ill get my *** in line and write up a thread on what I did

 

thanks for the pictures and the info. I bought a industrial manifold and was going to try that. I like how you clearanced the frame for the AC compressor, I cut my crossmember out and built a new one then boxed the frame in. and now I'm mounting a griffin radiator and electric fan and run into a few issues with that that im working through

 

Why are you running a different radiator??? Im running the stock replacement piece of **** plastic and aluminum radiator and it keeps that cummins running cooooool. Im usually running around 185-190 easy. If im on the highway pushing it with the 4.56s reving it out a little it might go up to 210-220. But then drops back down after I get off it. The funny thing is. I flipped the stock fan shroud and it matched up to the cummins fan PERFECT. Just saying though, If you couldnt work out the problem,The stock rad and all worked great for me... As for the Ac,I still have to get the lines mated up to each other. And its getting hot here so Ill eventually get to that.

 

when I installed the motor I had to leave room for the fuel return line to clear the firewall it comes out of the back of the head on the 24V so the motor doesnt sit back as far as yours so that cut my clearance between the stock radiator and the fan hub so I had to order a custom radiator,electric fan and shroud to make it all clear

on your ac I think fordcummins makes an adapter to attach the stock ford AC lines to the dodge AC compressor

 

Yeah my return line is also on the drivers rear of the engine. But I also have a 3 inch body lift. So I have a little more room than one with out. Im not 100% familiar with the newer cummins just the 89-95ish or so, Im only used to working a little bit on the computer controlled ones at this point. I had to test fit it to figure out where I was going to have it sit. I had that engine out I think 7 or 8 times until I was able to finally put it in for good..Well Anyway good luck. Any more questions just ask. Ill try to help if I can. And Im sure others on here as well. Ive had a lot of help on here myself with a couple problems,and plenty of peoples info helped me fix em.
