1.9TD "AAZ" Conversion

<< < (2/4) > >>

Hi Simon,

was not in this forum for some time, so sorry for late answers...

You can use the filter holder from Audi 100 1.6D or TD, also from Audi A4 1.9 TD or DTi. The are kind of 45° shape and have 3 channels instead of 2 channels. The only issue is that they are shorter than the VW ones. So you will need to make an adapter that is maybe 1 inch in thickness that you put between the motor block and the filter holder. We've done it this way for AAZ and 1Z conversions.

Regards,
Marc

I bought the parts from Mocal in the end.
I have not yet updated www.iltis.co.uk as I have been busy with work (T3 TDI conversion) plus the apprentice has been on holiday.
I used a filter head from a Audi that is swept backwards, I have then used a take off plate with pipes to a remote filter head.




I then have a thermostatic sandiwch plate which is going to a 13 row oil cooler behind the grille.


My apprentice cannot really help me with the TDI conversion so for the next few days he is on Iltis duty!

The Iltis clutch was not available to buy in the UK, I used the Audi item. Dimensionally identical, the springs in the clutch disc were however much larger than the Iltis item. The clutch that came out was 100% original and still had "Iltis" painted onto it.
I have kept the pressure plate incase that is stronger than the Audi item but as I say they looked identical. The Audi item was fitted to engines up to 2.1l in capacity, I'm confident that it is up to the job.

We used the original Golf clutch in the T3, shaved 4mm from the diameter of the flywheel to stop it fouling the starter motor nose.
we have fitted a 1Z motor.
We have the plate between the engine and gearbox made from sheet stainless steel so the lump on the 1Z flywheel does not foul it.
If you fitted a 1Z to a Iltis I should imagine you also have to remove the casting by the thermostat housing and the 2 lumps from the engine block so that the starter motor fits?
I did think about a TDI for the Iltis but it's the gearing that is the problem, you would not be able to drive at motorway speeds without modifying the gearbox? Unless you can tell me different?

Good morning, Simon,

you're right, a diesel engine without a modified gearbox is not really suitable for road use and an absolute nightmare on motorways.
There are some specialists who have modified the Iltis gearbox, using gear wheels from other Audi models, and also the Audi-based Porsche 924. The fourth gear should be considerably longer, the third slightly longer.
It was stupid that VW equipped the last series of the Iltis with diesel engines without changing the gear ratios.

By the way: all VW diesel engines with cast iron blocks and alloy cylinder heads are grateful for careful warming up!
