im going to drill, tap and plug the coolant passages for the electronics, is it worth my time to water cool the charger? i would be using the heater core ports on the motor would i connect the upper hole in the charger to the head or to the lower rad hose?
 
I'm figuring on hooking it up on mine. Not sure how I'll run it yet.

Was thinking about hooking it to the heater and drill/tap the elbow off of the thermostat for the return to the upper radiator hose. That way it will get cooled. Either that, or hook it in series with the heater supply side, and that will give me a bit more heat in the cab for winter.

Looks like it takes banjo bolts to hook it up on the turbo?
 
yeah they are a straight thread, so banjo makes sense. I will see if i can figure out what thread they are.

I dont run a heater core, or drive my truck in the winter lol.
 
The water lines are there to "cool" the electronics. So if those are being used, by all means, hook them up.
 
they are there for more than just the electronics, the whole center section has water passages in it, it will remove the need for a turbo timer, and might have some effect of keeping the vgt collar cool.
 
I doubt its needed without the electronics and highlydoubt it will help vanes sticking.

eh prolly not, i think i will still water cool it though.

Till you find out the banjo bolts cost $45 a piece! It is a metric banjo that seems to be an M18x1.50 Not certain on the thread pitch though, haven't been to Fastenal to check... But, if they fit I'll be making my own banjo bolts!

If you can measure the banjo/surround portions depth, let me know, & I'll check the banjo bolts I have from a years past DSM/Eagle Talon project. Believe the turbo ctr section water cooling banjo bolts on the DSM's were the same diameter/pitch.

Seems reasonably probable the depth is proportional to diameter on banjo bolts so they might work. If so, there are quite a few DSM's in the salvage yards.
 
I was thinking of the height of the banjo surround, that the banjo bolt clamps down on. But still guessing they're sort of a standard proportion - diameter to height.

Regardless, here are a couple pics of the bolts I have. It's been over a decade since I worked w/ the DSM turbo's but I believe these banjo bolts came from a DSM. Can confirm w/ friends if these bolts look like they'll be the right depth.

i just went to a -8

this way i can go to a 1/2" push lock or braided stainless pretty easily.
 
Seems most of the OEM water cooled ctr sections use banjo bolts & a short section of hardpipe, before converting to regular coolant hose.

Don't know if this is absolutely necessary. Certainly not from coolant system pressure. Maybe for longterm reliability of the portion of the plumbing close to the turbine section & the associated heat.

My initial thought was to see if the DSM turbo coolant hardpipes can be shaped/modded to go a little ways away from the turbo, then plumb into the coolant system as appropriate.

My situation is a bit different as the turbo is to go on a GM 6.5 diesel in the stock location, which is that asymmetrical mount on the passenger side exh manifold of the V8.
