Will a NA motor run ok with a turbo but no upgraded pump?

[wolf_walker]

So, cam lift = more fuel per injection event, and I assume cam ramp angle and duration effect.. Something.
And plunger size increase enables lower cam lift.   And that's probably dramatically simplified.

How are the AAZ cam plates different for the dual stage injectors?

Any guess on cam lift for a NA single staged injector 1.9?

Whats the diff between cranking the smoke screw and increasing injector shot via cam lift?

I assume injection duration is a thing here.

I spoke to a guy a few years back who had at some point in the eighties swapped in diesel to a scirocco and added an aftermarket turbo ran a small amount of boost and saw some serious mileage gains

Diesel Rocco is my other long term goal. :-)  Seen a few.

I am consistently getting 48-52mpg from the turbocharged '83 1.6 engine with a solid lifter head and NA IP in my '92 MKII Jetta. The engine is from a NA MK1 Rabbit.

After the timing belt broke in my '92 ECO diesel due to a seized tension pulley I decided to swap in the '83 motor instead of rebuilding the ECO engine.
I just swapped over the intake manifold, turbo and exhaust manifold, valve cover, oil filter mount with oil cooler and oil lines to the turbo, oil pan and pickup tube, clutch and flywheel (the clutch from the Rabbit had a broken spring), engine mounts (cut off the MKI passenger side mount), water pump (the MKI pump had a leak), alternator, and a couple of sensors due to different wiring harness plugs from the MKII ECO to the MKI NA motor.

I left the MKI NA injection pump, injectors and glow plugs in place. The only new parts I used were a new timing belt, tensioner pulley, oil pan and valve cover gaskets, plus new oil and filters.

I have over 15,000 miles on the car since the swap. The only problem I had since the swap was with the alternator belt and I solved that by going to a single belt system for the alt. & water pump (power steering and AC have been removed).

It feels like it has more power than the ECO engine plus it gets about five MPG more than ECO engine did.

I have said repeatedly that all the changes made to produce the ECO were for emissions (ecology) and NOT economy.  You should update your exhaust to be larger than the ECO version and eliminate the cat or make sure your max fuel is in the 'no smoke' zone.

Cat and resonator are gone, but the exhaust is still the stock diameter. The only time I ever notice any smoke is at high RPM in 2nd or 3rd gear under load. It is just a little light haze in the mirror. All other times I don't notice any smoke.

I have a 1.6td block, solid lifter head on my 79 rabbit that I have been driving the past few months.  It already had a straight through exhaust that is a tad bigger than the stock pipes and is using mk2 downpipe with t3 turbo.

I have a pump that I believe to be close to stock settings, the fuel collar was still on, etc. It was a pump I broke down cleaned and resealed from a junkyard engine.

I think I have the lda stuff set stock as well.  The car definately seems to pull better vs. the 85 jetta td I was introduced to a few years ago.

The only thing that makes me wonder is the egt's people mention.  I am using an auber gage setup currently and have been watching what the car does on hills in 4th gear pinned.

Just today while running a steady hill for a couple miles the egt's hit a high that I have seen of 1350.  The coolant temp gage went from the typical 190 up to 210+ where it would normally have the fan cycle to bring temps down if say sitting at idle for a while.  But during this run the fan kicking on just kind of kept the gage from going higher, wasn't able to bring the temps down like normal.

My car never smokes and I have a mk2 air filter on it with the inlet sticking through a hole I cut through the fender.

I wonder if there is something wrong with my setup and now I also wonder about slapping the turbo kit onto my other na healthy motor that is going into my truck.  I guess I will test that setup for sure with egt gage.  I only planned on using that motor in the truck until I rebuilt a native td motor.
