32B-JX: Questions and Answers

Hello everyone!

I have a Passat Variant with the JX engine.

Here are the questions I have:

- As far as I know, the JX is also used in the Golf GTD. Can I install that same cooler in my car and get it registered?
- Approximately how many horsepower does this setup produce? Does the oil cooler still provide a benefit in this configuration?
- How can I integrate an LDA here?
- If I want to replace the standard clock with a DZM (digital tachometer), is it enough to just remove the clock and install the DZM and its protective film?

I hope you can help me.

Regards,
Chris.

Hi Chris,

Okay, so a JX engine code was exclusively used in the T3 (VW Bus)! Specifically, from 1984 to 1992. If your Passat really has such an engine (which is rather unlikely), then someone installed it from a T3 into your Passat.
The JX differs from the passenger car versions in the following ways:
- anderer Krümmer, der Turbo sitzt in Höhe des 4. ZCylinders.
- different turbo type (smaller, more appealing)
- alternative ESP (designed to be flatter, as there is limited space above the engine compartment in the T3).
- No hydraulic lifters for valve lash compensation, but instead, bucket tappets.
- alternative oil pan/oil filler cap.
- other minor details, as the engine in the T3 is located at the rear.
The JX has the usual 70 horsepower and 138 Nm of torque.

According to my recollection, the following 1.6L TD engines were used in the Passat/Golf:
?? 60 HP Eco-TD, without low-loss cooling and without low-dust adhesion.
JR (?) 70 horsepower, without catalytic converter.
RA/SB 80 hp with low emission engine.

I'm just assuming you're talking about the SB engine with 80 horsepower!?
The SB has a different turbo (water-cooled!!) and a different ESP compared to the JR. The cylinder head was cast from a different alloy that is supposed to withstand higher temperatures.
You can certainly upgrade your engine with a different turbocharger and tune the ESP. This was common practice back then, and some tuners managed to extract up to 100 horsepower from the 1.6-liter engine. With extreme tuning, it's even possible to achieve 120 horsepower, but in that case, it's more likely to experience issues like excessive smoke, and it will be less practical for everyday use.
Tuning a 1.6 TD engine isn't particularly difficult, but it's unfortunately not cheap. You'll need an intercooler and an auxiliary oil cooler (highly recommended). More power can be achieved by increasing boost pressure (adjustable at the wastegate, and requiring adjustment of the blow-off valve) and increasing fuel injection volume (via the quantity adjustment screw). Fine-tuning the LDA (air mass sensor) can also help.

Jens.

Damn! I've messed up the entries again!

It's a JR model with 51 kW / 70 horsepower.

Of course, all questions refer to this engine.

Sorry again!

Chris.

Sure, here's the translation:

'Quick question for you.'
What does LDA mean here? Does it stand for 'load pressure adjustment'?
(Sorry for going off-topic)

Quick question in the meantime:

Boost pressure indicator.

He would like to be able to check the current pressure using a display.

Hello Chris,

Take a look at this forum http://forum.piranha-net.de/; it's about old pickles, while here, we're more focused on high-tech problems and their solutions.
The LLK (low-level coolant kit) from the 2-series Golf doesn't easily fit into the 32B; I have one from a Nissan (200 SX or something similar) installed: http://forum.piranha-net.de/download.php?id=113

@Dan.jel

I know that LDA usually stands for 'Ladedruckanzeige,' which translates to pressure gauge.
I thought this was about something else because 'Jens 16syncro' wrote it.

Fine-tuning the LDA model can also be helpful.

I don't believe that it provides more power if you tamper with an advertisement. That's why my question is...

Hello,

Jens is referring to the boost pressure enrichment at the fuel injection pump.
As the boost pressure increases, an additional amount of fuel is injected.

Best regards, Rainer.
