Getting there: Parts arriving, engine getting done

The parts above arrived and the engine is done. One part is sadly missing which is still that tensioner, prolly somewhere in the mail.
Engine builder said, it was horrible working on the car. A lot of crap was done to it before.
The exhaust is as thought a Kakimoto, but 2 hangars a missing and one is bent a little and I also need to buy exhaust gaskets for it pretty soon as well.
I am trying to figure out what to do with the ECU, as its not just a simple plug and play, but will prolly have the water system run on its own sensor without the ECU, as thats the major difference in the 2.

I will post all pics as soon as i can, but ive been travelling around a bit.
