Germany is in EU so I do not need to go there. I can order car parts from all countries in EU without extra customs charges etc. But best would be to find something on Swedish junkyards. I've managed to fit a "standard" Volvo, Pegeout, Saab etc. injector to a UT Mk I (and X?) by using a rubber hose that fits exactly to the drilled hole on the inlet. I am not using the plastic adapter between the injector and inlet tube because I realized it would break. The UT/X injectors do not have an O-ring, they have a round gasket that seals by pressure from the injector mounting ring. I assume an O-ring would cause the plastic adapter to crack over time.
As you see the Volvo 240,740,940 injector to the left doesn't differ much from the UT injector to the right except the O-ring:

By adding a rubber hose that fits exactly to the hole on the inlet tube, with an inner diameter of 14mm, and reusing the rubber ring and mounting ring from UT it looks like this:

This is super tight and opens up for a lot of options. The upper part of the injector is still causing a problem but can easily be solved by the (overpriced) Australian converter/adapter mentioned in earlier posts.
(The picture above is just a test. I will clean it up, have a pair of tubes instead of washers ;-))
However, one thing in this setup is worrying me a little bit. The Volvo injector will be closer to the inlet compared to the UT injector:

I don't know if this will have an impact on spray pattern. To me it looks like the Volvo injector would be more efficient. It at least looks better? What is yor oppinion?
The Volvo 960 Turbo injectors would be my first choice for my application. They deliver 310-330cc/min and that should be good for the 200hp I am aiming for on my UT Mk1 engine.
I've also found a complete list of Bosch injectors. I will structure it in an Excel file and publish it later.
I've discussed a turbo upgrade with GIK Turbo Sweden, they are a Holset, Garrett and IHI representative. There is not much space for a bigger turbo, the alternator is very close to the downpipe. They offered me to rebuild the IHI VL3 with a bigger turbine which was quite costly (700$). Speedy Fiat, Did you upgrade the turbo? I would love to hear more about your mods.
