I've done some searching on this subject and the consensus is to install it in the LH manifold behind #7. Is this the same for the turbo application?

I'm thinking that it should be in a more central location so that it is picking up a median temp of both banks. Maybe the lower end of the up pipe to the turbo exhaust side inlet?

Are the exhaust manifolds the same between the NA and the turbo?

Am I going to need to buy another return line kit to reroute for the turbo?

As far as the glow plug controller relocation, I have the harness for the factory turbo application, but it isn't in the best shape. Are most just extending the wiring from the NA harness?

I'm .taking it as you are talking about the pyro probe in your first question. Most say to install it in the drivers side exhaust manifold. As Dave S. explained, the aluminum the pistons are made out of, starts to melt at something like 1250 degrees, so he wanted the probe as close to the pistons to see what temps they were exposed to. There was a thread on the OBS stroke forum where A member was running 2 pyros for comparison, one in the manifold, and one in the down pipe after turbo. His findings was from 25 degrees at idle, to near 500 degrees at ***** to the wall, higher in the manifold
The manifolds are the same on both the turbo and nonturbo motors. I'm talking about the factory ATS turbos, as I've never messed with the Banks ones.
The returrn line routing is is different with the turbo, but you might get by with just changint the cross over line that goes from the rear passanger side to the rear drivers side. On a nonturboed one it runs under where the turbo will set. Just take a longer piece of hose, and run it from the rear nipple on the passenger side, around the front of the air intake in the center of the engine, to the port on the rear of the drivers side.
When I installed the drop in turboed motor in the 90, the glow plug controler was in the same place as the nonturboed motor, at the rear of the motor. It has been there for nearly 100 K miles. So when I put the turbo on the 85, I just left it there. Even though the two systems are different.

 

Return lines arent too picky as long as they are sealed. I re ran mine so number 7 goes to the filter head and number 1 goes to number 8. Sounds stupid but it go around needing a long loop to go around the front of the intake.

 

What turbo kit are you installing?

 

if using a banks turbo, the thermocouple mounts in the turbo pedestal.
and banks uses stock ford manifolds.

 

Thanks for the replies. It is a stock ATS setup, hopefully with a 3" outlet. Or at least with a real downpipe.

I've read that about wanting to protect the pistons from meltdown. So if you install it in the rear of the LH manifold, what happens if you have an injector failure on #2 cyl, opposite corner? Would it go unnoticed because it is so far away from the probe?

Will the turbo downpipe connect to the exhaust behind the Y, or will I need to have some exhaust work done?

Thank you guys,

Jason

 

Easiest way to rig exhaust is to cut the y out and run some sorta straight pipe even if its just stock size. Mine is 3 inch all the way and the noise isnt even noticeable at speed. As far as the probe, if your that worried about a single bank reading you could just as easily drill and tap the cast collector and knock a couple degrees off your max reading.

 

An injector failure won't necessarily show up in EGTs at least to a noticeable level.

All the turbo kits I know of attach to the exhaust manifolds with a custom up-pipe and a custom crossover pipe.

 

I drilled and tapped the drivers side manifold cylinder #6. I did it there because there is a spot cast that looks like it is for that purpose. It is on #2, 4 and 6 but not 8. I wanted the thicker material, afraid of cracks. The manifold is still on the floor and not installed yet. I can take and post a picture tomorrow if you need. I was going to do that along with other pictures once I got it installed and have both EGT hooked up at same time. 1 in exhaust manifold and 1 post turbo. I might have to loan truck to a friend before I can finish job though, so it could be a week or 2 before I finish. The manifold is my spare.

 

On the ATS 093 system, the turbo up pipe, which is kind of like an inverted y, mounts to the passenger side manifold, the a cross over pipe runs from the drivers side manifold ,under the tranny, where it bolts to the motor, to the bottom of the up pipe. The stock non turboed y pipe is removed, and not used. The stock exhaust should be upgraded to 3" for best results.

 

It depends on how it fails. If it is underfueling, you probably wouldn't notice anything. But if one was stuck open or overfueling to the point of meltdown...
Maybe I'm overthinking it.

On the ATS kit, there is a Y adaptor that goes on the RH manifold that feeds the up pipe and has a crossover from the LH side.

I will eventually upgrade to 3". My focus right now is to just get it driveable and back on the road where I can get some bugs worked out.

The sensor is in the #6 exhaust port, driver side manifold. The other is the passenger side manifold. The passenger side manifold does have areas cast in all 4 ports.



Closer view you can see the cast flats better.



You can see the EGT probe will almost go down the exhaust port in the head.

 

I don't think an injector stuck open can over-fuel much on these. The timing would sure be messed up, but the volume is controlled by the pump. A stuck injector can't dump a huge volume of fuel like a HEUI injector can...
