Ecodiesel and other questions

[meanvw]

Been searching and reading.... Maybe just haven't found the right post yet.

I have an 83 rabbit that I rebuilt the 1.6l diesel about 6000 miles ago.
Used a 1.6td bottom end from a quantum that has the piston squirters.
Rings, bearings, head, pump got some new seals, injectors got rebuilt with new nozzles. So, Everything is pretty fresh.  FN code transmission with .71 5th gear. 

I drive 160 miles a day commute -all interstate.  Car runs 65mph no problem.  Pretty peppy from 0-45 mph, 45-65 is painfully slow, but once at 65 I have no problems maintaining speed on hills.   I average 51mpg.

Have someone locally selling off Ecodiesel parts.  Exhaust mani, turbo, intake mani, connector between turbo and intake, feed and return lines, and oil pan.  Asking price is $200.  If stuff is in good shape, what is a good price?

My goals would be to improve that 45-65mph acceleration, and also improve fuel economy. 

He doesn't have any other parts, so i think I'd need to find/make a down pipe.  I would plan on just running my non turbo injection pump.

My other thought is to just forget about this turbo setup and continue banking money until I can afford a Giles pump re-build.

Coach me on which is the better decision.

Oh yeah.. The other question is, I have 6000 miles on the new motor.  Initial fill and first oil change I did rotella dino motor oil.  Should I go one more (or a couple more) oil changes before switching to synthetic?

My MPG has improved from 46mpg initially to a consistent 51mpg now which to means the rings have probably broken in?

Giles is much simpler and more reliable, plus it doesn't clutter up the engine bay like turbo nonsense will.

You have potential for much more power with a turbo though. It's my personal opinion that the eco diesel K14 is the ideal turbo for what you are describing because it is small so it should spool well without the extra fuel but isn't so small to cause a restriction like the K03 would. If everything is in good shape, $200 is a very good price.

I have never run a turbo on a NA but I would guess that the Giles pump would ultimately give better mileage. Maybe someone with real world experience can comment though.

I'm rebuilding a 1.6 now with some of the same ideas in mind. I plan on getting the IP and injectors rebuilt by Giles. It is rather expensive but I have not heard a single person not amazed at the work he does.

as for MPG, 60% of the fuel spent 45mph and above is fighting air resistance. If you make some modifications to the body, you can save some fuel.

Do some research on google, you will get all kinds of ideas.

This is what the guy has for sale for $200.  Going to look at this weekend.  Would think this would (I know it's never this easy) "bolt right up" .  Only thing I would need to fabricate would be the intake/air filter.  Am I right or am I missing something?

Think I may do this since these parts don't seem to come along often.

Anyone want to weigh in on at what mileage would be ok to go to synthetic on a new motor.

You might need the oil filter flange so you can hook up the oil feed for the turbo. Check the downpipe for rot near where the c-clips hook on. Obviously you will need new gaskets. Check to make sure that both fittings for the oil feed line are there.

You should put in a larger oil pump while you have the pan off. I think you will have a 32mm one and the turbo engines used 36mm pumps. I think you are also going to need to fabricate a lower downpipe

I think that 10,000 miles is good on a new engine. 5,000 is probably good. I wouldn't run it before 5,000 even if you aren't consuming oil.

I have the quantum turbo diesel bottom end, including the big oil pump on the car,  I have the quantum td oil filter flange pictured above on the left.  I think that may work?  Almost looks like that flange from the quantum orients the filter sideways?  That's the only pic I have, will have to look at it again when I get home.

I was looking at parts place website and the exhaust they list is same part for both turbo and non turbo cars... I was wondering if it would bolt up to my existing stock exhaust or not...

I can't find, or see from the pics I can find on the web how/where the crank case vent is routed on the turbo car??  I would think routing it into the air intake would gunk things up?  I have a g60 16v gasser scirocco.  I used to have the pcv routed before the charger, and was always getting water/oil mix in my intercooler.  Was supposed to be good for that g60 charger to have the oil mist from the crank case for lubrication...  Running a catch can on that car to solve that problem, but the catch can solution literally stinks... Can always smell oil.

The diesel seels to push much more air out the pcv than a gasser does... So what's the solution on routing the pcv to minimize bad smells?
