Title: New to the scene
Post by: MK2_Jeff on October 23, 2006, 08:58:30 pm
Hey everybody, brand new to these forums as well as the diesel scene. Basically new to the car scene period. Im 17 and just bought my first car, a '91 Jetta 1.6 TD. I'm pretty pumped to finally snag myself a dub. Anyways, its slow as hell right now, I'm fairly sure it has one of the smaller k14 (I think thats what it is) turbos. Anyways what should my first steps in getting a bit more speed out of the car be? I've heard intake, manual boost control, and exhaust. Is this about right?

- Jeff

well since your new to the car scene i got some pointers for you.

change your oil religiously. monitor your oil level (since you will be driving it hard) and let the car warm up before beating on it or you will be sorry.  Also, you MUST keep an eye on engine temps.  An accident on the highway caught my eyes and lead them away from monitoring my motor... it overheated and screwed a bunch of stuff up.  Remember that the extra back pressure from the turbo will heat up the head a lot quicker than non turbo.  try to keep rpm's low when cold.

once you have all those pointers down... you start on performance mods. :)  first things first... get an intercooler!  the rest is pretty much turn key... and/or turn screw :)

Cool, thanks guys.

Sounds like tweaking these diesels isn't as hard as I figured it would be. But I'm more than likely wrong.  :lol:

ECOdiesel upgrade:

Step 1:  Review the archives of this forum.

Step 2:  Remove the entire exhaust from the turbo back and replace with 2.25" or larger diameter free flowing exhaust.

Step 3:  Appropriate timing might lead you to do at the same time as step 1, but funds might not.  Anyway, add an EGT gauge pre-turbine.

Step 4:  Get an aneroid pump and attach it to the intake manifold.  Adjust fueling according to EGTs.

Step 5:  Add an intercooler

Step 6:  Increase boost and fueling.

I put them in that particular order for good reason.   :wink:

I have one question, what is attach an aneroid pump in to the intake, what is that, can u explain me a little bit  :roll:  :roll:

a 91-92 Eco diesel used a n/a pump basically. It wouldnt add extra fuel according to boost levels. The aneroid pump has a special..well..aneroid on the top that increases fuel according to boost levels. Its actually ON the pump and has a hose plumbed into the intake manifold.

N/A pump (Thanks to whom Ive stolen the pictures from)

There's plenty of information on this in the archives, but the LDA (aneroid device) on a TD injection pump looks like this:

(http://www.hostdub.com/albums/veeman_album07/pompe_turbo_LDA.jpg) (http://www.hostdub.com/veeman_album07:pompe_turbo_LDA)

Some people refer to it as the "spaceship" because of its shape, but basically, it's a boost enrichment device mounted on the injection pump that uses manifold pressure to proportionally adjust fueling under turbo boost.  More boost = more fuel.

The NA (obviously) and ECO pumps don't usually have the LDA on the pump (except for some where there's an altitude compensation device in its place, I believe), so the top of the pump on those is more flat.

he doesn't have his location set up... don't know where he is from?  Canada models of 91 diesels have the aneroid :)

was there ever an eco diesel in Canada???

Yeah I'm in Canada.

I have a suspicion that its not an ecodiesel.

I'm pretty sure there was. I almost bought one it Ottawa once, I never saw it though but it was advertised as an ECO.

well thanks to the guys who posted pics in this thread!  if you have the aneroid that is in those pictures, you have the real TD :)

all you need to do for cheap, effective performance increase is add the intercooler.   you would be amazed at how much heat the intercooler will give off after a nice drive. :)

look for the DIY thread for more power.  that is basically what you need.  don't forget to follow what i've wrote up top.  good pointers...  much better than learning the hard way hehehe

forgot to add.. if your car comes with A/C then keep a good eye on engine temps.  I've never owned a vw/audi with overheating problems that do not have a/c.  No matter how hard driven, they always stay cool.

when I was on the highway, the driving was keeping my car cool.  slowed down because of a stupid motor vehicle collision (no more accidents) and since the car being a very recent purchase, did not think the fan would be blown already.  Turns out it was... and I was notified by the overheating by steam coming from my car... aaaarrrrrghhhh don't let it happen to you!
