I highly recommend going over to PCMHacking.net. A lot of smart guys over there that might be able to help. They mostly play with gasoline ECM's, but the concepts and methodologies used are basically the same as you are wanting to do on this diesel ECM.

There are some very good Bosch guru's out there, if you can find one to tackle it. As you can see in the video, just learning to use the tools is it's own months long course. With proper a2l or map file, it speeds up the searching process a good bit.

Update on the turbos.

Got the pedestal built. Going with AN fittings and stainless braided line for the feed and drain to the turbos. Hope fully they will handle the heat up in the valley. Still searching for someone that will be able to hack the LMM file, i joined PCM hacking forum so maybe will find someone on there.

Deciding on how i want to do intercooler piping. I like the idea of keeping everything parallel including the turbo intakes. That way i would end up with a air filter behind each headlight but that would required fuse box relocation or replacement with something smaller. Also thinking about doin a dual intake y bridge, but that would keep each bank completely seperate from each other, i suppose i could have the y bridge crossover and also make it so left feeds right and vice versa. undecided on that since i also like the look of the valley being feed with one big 4 inch pipe.

low mount A/C and alternator are panning out very nice. There is plenty of real estate to hide them on the bottom right side of engine.IMG_8240.jpgIMG_8239.jpg

Ive been staring at coolant diagrams alot today. Someone please make this makes sense lol.

Regarding heater core coolant lines. My one hose goes into the lower rad hose so lets call that pump suction.

In the picture below: 1) is where a LB7 other heater core hose goes into, supposed to be "pressure coming from heads" cavity under thermostat, right? So that would reason that position 2 is also cavity under the thermostat, BUT position 2 is also pump suction. Is there enough of a pressure differential at position 2 that my heater core would function? This seems like it would work as much as it seems like it wont..... ive definetly been staring at diagrams to long 🤪

Oh, or would the bypass not really se any flow once the thermostat opens? but it has to because thats where the turbo coolant comes back, which also must mean it a "suction side" someone please confirm or deny or pour me a drink.

#2 would depend on the thermostat position, closed it recirculating the coolant back to the pump, open or blocks the tube forcing most of the coolant to go towards the radiator.
Should be some flow, but I doubt as much if it was dumping into the low pressure side of the radiator

Normal #2 is part of the turbo coolant circuit.. which I can't remember which way it flows

That is exactly what I needed to hear, I totally forgot about the t stat closing that off.

Got the Exhaust done. Ended up fitting pretty good, didn't need to squish any pipes and have good clearance around the down pipes. Just the one heater core hose will be kind of close. I will header wrap these at some point. Surprisingly the down pipes are pretty easy to remove, as long as the car is high enough off the ground, they slide right out the bottom. With everything installed nothing hangs down past the lowest point of the uni-body which you can see in the last pic.

Twins in the valley? On a car? Dang man, thats just nuts. I cant say anyone's ever put them that way on a truck, even though there's more room to do it!

Yeah, i was just going to ask if you mocked it up with flipped manifolds. That is right tight.

I think it looks tighter in the pics the real life, they actually fit really nice. The strut bar still fits and clears well. So all this will still be under the stock hood.

I did toss around flipped manifolds. Right away the turbos are into the rad and also the fuse box on the passenger side. Would have to slide the engine back a few inches but then none of the factory mounts/shifter location line up and I didn’t wanna give that up. I still love the fact that all this is mounted with factory parts.

There is one guy that’s has on a truck. He is on this forum and has an old thread with pictures. I don’t think he is active anymore tho. I’d like for him to see this. Edit: he’s on diesel place

I know I'm late to answer here and Adam already did a good job of answering your question, but since I'm just now seeing it, I will go ahead and answer just for clarity. The port labeled #1 in your picture is like you said, always under pressure pushing coolant out. The port at #2 is always suction and is used as the suction side of the turbo cooling circuit (the thermostat housing you are holding appears to be from an LML, and it looks like the pipe plug next to port 1 is blocking what would be the feed for the turbo cooling circuit). Port 2 will have less suction when the thermostat is closed because the tube it is tied into is the bypass for the thermostat to recirculate coolant through the engine when the thermostats aren't allowing coolant flow past them to keep from dead heading the pump and preventing hot spots in the block and heads. Once the thermostats open, the bypass pipe is blocked at the top by the front thermostat allowing the water pump to have more of a pull on port 2.

Looking at y-bridges here. I think I’ve settled on a single intake pipe. The two turbos will feed into a dual inlet intercooler and then a single 3 inch out.

I’ll go with ppei or pusher. Really what I’d like to know is which one will give me better clearance for the two intake pipes that will come off the turbos. They will both sweep to he drivers side front corner of the car.

Anyone got any pics installed?

HSP used to have a really nice 2 piece y-bridge that would work well and allow easy modification for your piping.
