TDi-M Turbo and Fuel Questions

[RabbitJockey]

it's the pump you can tune them by ear but you still need a dial indicator.  you should definetly look into a real pump builder instead of these panzees

Well both pump builders do come highly recommened.

The first pump that I had was used but build by a shop in the Czeck Republic. Customs actucally damaged some of the injection pump (they stood on it there was a perfect imprint of a foot, when the motor and injection pump was shipped). I was told that the motor was "fine" and was assured that if anything happened that another pump was ready and waiting for me if I needed it. Well it turns out that the TDi-M pumps were just 1.6L and 1.9L TD pumps mistakenly brought over. I have contacted others that have used these pumps and everyone is delighted with them, no one has complained. The pump going bad was not the builders fault on this one, it could have been from shipping or that the pump was shot before I obtiained it, much like the motor. Its hard to tell from the pictures, but the LDA was present at one point on this pump, it had been cut off for some reason or another.

The second shop I had never heard of. I contacted a person in the states that then recommened me to them and sang phrase of the work that they had done before. He had personally used his pumps in a couple of TDi-M converisons. I have had experance with this person before and it was nothing but pleasant, and he was very very helpful. I when I talked to the shop owner that built the pump he was nothing but pleasant and helpful. So far the pump does do what it is supposed to do kind of , it starts and runs the motor. It does a great job of this, but its like the pump lacks advancement or proper fueling. Its like driving with the cold start handle pulled out. Could this be due to improper timming, could be but currently I have no way of checking, nor the time at the moment to track down a shop that does have one. I have a weeks vacation comming up and hope to get the pump timmied atleast in that week to see if it aids anything. I would like to get this pump timmied so that I know I have done everything that I could do to make it run right before I "burn any bridges"

If the pump that is supposed to be shipped to me actually shows up and fits my motor, has a LDA, and actually runs properly (enough things that need to go right in a build that has been nothing but problems, headachs, and let downs). Ill be removing the pump that is currently on there and asking for at least a partial refund

Anyone know how this story ends???

I've talked to the builder of this 1.6 NA hybrid m-TDI pump.  Kelch's in Ohio.  He says he's built like 100 of them and they work like a charm.

Anyone out there one of those 100 that can offer some feedback on how this setup works?  

Thanks, Joel

Where at in ohio is it?

I found out about these guys through Jack at vwparts.com, so I assume they've been around awhile.

[jimfoo]

Did you ever talk to the place in Denver? If so, what did they say?

[Joelwesty]

Not yet, trying to research the "known" rebuilders of M-TDI pumps first.

i think it is a ford 1.6 diesel pump 84 to 88, i have turned one into a Mtdi pump and put a lda on it to

Hi Guys

strange that no-one has memtioned my name in all this mess.

my pumps do work well and give equal or better performance
than the electronic setup.

Giles If i was to send you a pump and some parts for you to make a mTDI pump what would you need? Would it be cheaper or just buying one out right be a better route?

Who doesn't know your name? I think Joel would love one of your pumps, but just doesn't have the $, so he was looking for cheaper, though less performance, alternatives.

[Joelwesty]

I think Joel just wanted to know how an M-TDI pump built from a 1.6 NA pump worked on the original poster's car.     Too bad the guy that started the thread is apparently MIA.  Oh well, always nice to wake up an old thread for a while.  Joel

i bought vdub_fun's injection pump (the one from czech) and gave it to Giles to have him do it up with a 1.6 LDA.  he's the MAN!   :lol:  he ran some tests on the pump and said that it was putting out some insane fueling!!! enough to melt my motor if i ever flogged it  :lol:.  it seems as though the pump builder tried to incorporate an LDA function by just increasing the fueling up top, as if there was going to be that 10 psi from the turbo.. thing is.. if the turbo ever failed or you blew a line and lost that boost, BOOM black smoke cloud of DEATH and your motor is going to cook.

if you're reading this Giles, maybe you can elaborate more on your findings  :lol:

i'm still very anxious to get this pump running on my mTDI, but i need to find a damn injection pump bracket for a 1Z.  i'm actually contemplating biting the bullet and buying one from the dealer... $150 later... but from what i've put into the motor already that wouldn't be much to actually have a good running motor (not that my 1.6TD isnt good running, but it burns a bit more oil than i would like, and the pump could use some tuning etc... not to mention new pistons, and theres something wrong with the head  :roll:)

Hey guys
i know that everyone wants to get good stuff for nothing and i don't blame
them.

for me to make an M-TDI pump i need two pumps. one TDI pump and one
AAZ pump with the same mounting diameter as the TDI.
then it's $1400 to build and test the pump.

hope this clears things.

that pump that Johnathon gave me i put it on the test stand and gave
almost 300% over fueling all the time with no LDA effect (it had none)
it also had no dynamic timing advance what so ever. who ever built
it did not test it on a Test bench for sure. it might have run on the
engine but it would not run very well, black smoke all the time and
whit smoke too for sure when you don't have your foot into it.
