Hello, GTD.
New member from Orlando, Fl here. (12+ years driving Mk2 + Mk3 VWs, but brand new to Diesels!
I thought you might like to see another Jetta IDI TD.
Its an 85 w/ Garrett T3.
Odometer reads 70,xxx miles (and works), but PO said it was 180,xxx when he sold it...?
PO installed: 15" G60 steelies, VMAXX coilovers.
I added: Big intake, Manual boost controller (set to 19 PSI), VDO gauges (EGT W/ Spruce thermocouple, Boost, and Oil pressure), and aesthetic touches (GLi spoiler, Yakima rack w/ basket, euro plate)
dropped a further 1.5" from these pictures.
Next on the list:
1) Drill and tap manifold for Thermocouple
2) 3" Stainless Downpipe into 2.5" Straight pipe w/ resonator
3) reset boost to....?
What should I do?
Looking for sage wisdom.....
Thanks in advance!

Any advice appreciated!
Thanks,

problem of the day is:
VDO oil pressure sender (OEM from VW Cabby)
will not fit with the vacuum pump where the switch is on top of Oil Filter hsg.
Some kind of adapter is needed to install this.
Suggestions?

Jettagli, hello from a fellow Newbie, and er welcome...
Your getta looks very clean; never had a Mk2 'shape'; the brother had a GTI 'clone' 1600(petrol/gasser)that was ropey but quick, as he used to get racing fuel off a rallying friend...
A bit 'off topic' I spy you have a T2 'bay; I also have one but the body is poor (rot!) but has a tuned aircooled motor, but am toying with the idea of converting it to a TD...
I'd loose the square lamps from below the bumper, personally...
-
but I went to so much trouble to add those lights!
and stock, US spec lights suck!
-
Injection pump is where you will get the most performance results with the least money. Do the governor mod, up the fuel, and adjust the aneroid. Costs nothing and takes very little time.
-
what kind of seal do you have on the blow off valve? you can remove the screw inside and insert a longer one to block it off... :wink:
-
I was planning on bypassing all the little IP mods, and doing everything around the motor and turbo, and then sending it to GIles..
I dont think I need any more fuel. at 15 PSI, it was fill the highway smoky at full throttle, at 19 PSI it got better, but still plenty of black smoke at full boost.
Doesnt that mean I have enough fuel? (I wont touch the IP until my EGT is installed anyways, just ot know...)
And, more to the point, arent all of the mods to increase fuel?
I "Eliminated" the recirc. valve with a big vacuum cap, and a cable tie.
Seems to be holding fine.
The standard 8v gas manifold seems to be the nice upgrade, so I was going to just wait for one of those (instead of fabbing a nice plug or whatever)...
All of these are my guesses, tell me if I am wrong!
Thanks!

Welcome !! I like your air filter (I'm using a similar one in my 1.6L TD Caravan) - Did you make the pipes ?
-
Yes, sure did!
And Thanks!
It was all random bits bought locally.
It sounds great! you can really hear the turbo spool.
I know Diesels are funny about their intake air, so I figured I ought to make sure I would have no worries!

6 hrs into Spruce EGT probe install...
The manifold has broken one tap, and stymied another.
We were trying to drill and tap with the manifold on the car,
and after breaking the tap in the manifold,
removed it.
Now my new (admittedly cheap) Harbor Freight tap set will not even phase the cast iron.
We will try a new, better set of Taps tomorrow, from a friend at a machine shop that regularly taps cast iron with this brand / style.
Also in this service:
New Oil feed and return lines (OEM) - Return leaking, feed prone to coking up.
New oil pan (PO stripped drain plug beyond belief!)
The turbo came off in under 45 minutes...
I thought that was going to be the hard part!!!
more to follow,

You should sell those god awful steelies... to me :D

Update:
Well, if I can make a recommendation to anyone installing a Spruce (or any, for that matter) thermocouple in the exh manifold,
I HIGHLY recommend Jarvis taps.
We spent 3 hours last night trying to tap the manifold with an old, but good tap, and broke that, went to a brand new set from Harbor freight,
and this Jarvis tap did more in 2 turns with less effort than anything else.
Egt is mechanically installed now, wiring to follow in the next hour or 2.
-Brad

VICTORY!!!!
Egt installed,
Oil pan, and lines installed (no leaks!)
and WOW,
that Spruce Thermocouple reacts VERY quickly.
I can see it drop at least 300-400 between shifts!
Anyone want a free VDO Thermocouple with bung?
let me know!

I'd put back the oem filter box and use a VW air filter. Flows and cleans better. K&N's don't work as well as they look.

X2...
I was looking at the stock paper filter next to the K&N filter that was on my car when I got it. If I curl the stock filter into a tube it's pretty obvious it has WAY more surface area than the K&N filter does. Granted the stock airbox snorkels are a major restriction, but that's easily fixed.
I like the way the car sounds with the stock air box a lot better too... Can't hear the turbo as much but it totally lowered the tone of the engine noise, made it "deeper" than it was with the K&N

How old are your injectors?

You need to flip the turbo and exhaust manifold upside down, which then requires a lot of custom work as I'm sure you can imagine.
It looks like your car is an ecodiesel, have you deleted the cat yet? An exhaust upgrade will be very noticeable on your car. The turbo will spool a lot faster.
-
I like the project. That was my favorite body style. I had 2 of them new.
IMHO, watch the high boost on a stock engine - 15psi max. Get a manual boost controller.
Get some ARP or Raceware head studs in to save the head gasket. You can change them individually without lifting the head.
Send the pump to Giles for a performance rebuild...money well spent.
Get a 2.5" downpipe and exhaust system - it'll free up, and cool down, the exhaust.
Intercooler is a must. I'm using one from a Saab. They're called a Blackstone unit and are small but very efficient.
-
To my understanding,
the worst thing you can do to a Diesel is restrict the airflow to the intake.
(Same fuel, less air = high EGT?)
Intake, and exhaust is always the #1 thing to do to ANY car to begin adjusting the performance envelope away from what the factory provided.
Sorry, but you will have to provide empirical data to make me believe that a factory airbox with a paper filter is better than a 3" pipe going into a 2.5" hose directly to the turbo. (and look again, the stock element is NOT EVEN CLOSE to my admittedly oversized air filter in dimensions.)
Basically, you are trying to make a case for the stock intake...?
Nothing personal, but I want more from my car than the factory intended.
Factory design has many factors: Overall comfort for 99% of car buyers, and cheap cost trump outright performance.
Now all I have to do is undo those things!
Guess what, I am also getting ready to install a 3" Downpipe into a 2.5" SS exhaust system...
That is far bigger than factory too....
You guys must not like going fast.
Thanks anyway!

Burn your money:
Injectors are (presumeably) original...
I would like to do the Giles pump and injectors from same at the next phase...
And Yes, that is a lot of work for a gasser manifold.
Maybe i will work out something custom like Dave @ Passenger used to make..
Also, NOT an ecodiesel, just put the badge on.
(People who dont know will understand the smoke, and people who know they did not make a skinny bumper ECO will get a rise out of it!)
Stewardc:
Thanks for the compliment!
I have set it at 19 PSI for the moment, (Holding OK so far!!)
but my plans are:
1) 3" SS exhaust,
2) ARP Head studs and metal gasket
3) Giles pump and injectors.
Thanks for all the advice!
(Except those trying to extol the virtues of a stock airbox... I have never appreciated them!)
