my Wagon is sluggish, Always has been. It's rare for my RPM's to go over 2,000 unless I really push it. Freeway driving is mostly with the pedal to the floor Cruising 70. if I push it I can get the RPM's above 2,000 but thats far and few between...Idk if my Turbo is not kicking in or not. I certainly cant hear it when I have the car running like I can on the cummins and powerstroke albeit they are huge engines.. What should I be looking for on this? I noticed a small pass thru bolt with a hose on it near the bottom of the Turbo, and there's a Vac line to it to that branches off and goes to a metalic Round part near the front under the air cleaner. where it shoots to after that i dont know.

I'd guess your turbo ain't spooling. you need to open it up and make sure its not stuck. but then i've rarely worked on the older cars until i bought my td a few weeks back.

Is the linkage to the injection pump fully advancing with the pedal?

as barry123400 said. My Car had that problem. Tightend up the Linkages and it normalized.

I guess we are assuming there is no Fue Supply Restriction.

There could be another IP issue. If whey you step all the way down on the Pedal the Throttle arm on the IP is touching its stop. It could be that that stop needs to be adjusted. Part of what that Stop does is adjust the seed at wich the Governor would start to shutdown your Engine at high RPMs.

For below: Transmission in Park and the Parking Brake engaged.
After you are sure the Throttle is going all the way to the stop and with the Engine warmed up to operating temp (your Tachometer needs to be working) kind of a slow fast step on the accelerator and rev the Engine and see how high it will go on the Tach before the Governor limits it. You do not want to stay at that speel long just enough to note the speed. I do not know the exact spec except that it is between 4,000-5,000 rpm. Somewhere in that range the Govern should prevent you from going any more.

If does not reach at least 4,000 rpms I would adjust the Throttle lever Stop screw until I get that.

Note: This high no load setting is there to protect the Engine from over speeding. Your not going to go more than a few mph faster buy raising that speed beyond what the factory wants. But, if it is set too low you will not reach your normal Max speed.

For the most part ounce a Fuel Injection Pump leaves the Factory no one messes with the adjustment unless a specific problem shows up or somebody fools with the screw because they do not know what it is.

CORRECTION: These instructions are for a 123. I do not know if an 87 300TD has the mentioned port.
You could hook up a pressure gauge to your intake Manifold to see if your Turbo is boosting. Forced Induction on another Forum said words to this effect: Port for installing a Boost Gauge at rear of Intake manifold on the Air Filter Housing Side.
M10x1.0 port behind the air filter housing.

I believe max normal boost is 10-12 psi.

is the ALDA some way Connected to the turbo and it's signal is just not getting through?

I've checked the linkage between the pedal and the assembly, and when the pedal is floored so is the linkage.. I'll look at the turbo etc tomorrow and see if it spins or has abnormal play

You can take the elbow off the inlet to the turbo & watch it spin. If the car has an EGR valve, you may have a blocked inlet manifold.

Look into the archives for the alda circuit. The system that controls it seems to soot up over time on most these turbo cars. Almost a long term maintenance item.

There is a port on the intake manifold that reads the inside boost pressure. A feeder hose to an overboost device and then the hose goes on to control the alda on the injection pump. If this system obstructs and they will . You get boost pressure from the turbo. Yet the alda does not get the signal to increase fuel with the boost. So power is very low.

Always a mandatory check like the linkage was anytime an issue like yours rears it's head. Tons of information in the archives as it is such a common issue.

Where are you at in Florida? I am in ocala and would travel to help you out if you are not too far away. I have the same car.

Let's get a bottom line here:

When was the last time you change your fuel filters?

My car still has an EGR but the intake and Crossover system has been off several times with no blockages or build up noticed

There's a banjo bolt at the rear of the intake manifold that must be clear for the IP to deliver the proper amount of fuel under boost. If the bolt is clogged you'll get sluggish performance. Barry123400 mentioned the circuit but the bolt is a common bottleneck.

Does diesel Giant or someone have a good pictorial of the whole boost system?

I don't think you need your turbo to get the RPMs over 2000, the engine should be able to do that without it. This sounds more basic, like a fuel problem.
