Got donor car, question about engine replacement

[Kiss Me Deadly]

i`ve finally got this:






VIN plate:


The engine was replaced by previous owner to, i guess, JDM engine, because it has no EGR, right?

I wonder why the car has no O2 sensors at all, even harness, this is the picture of exaust, it all stock, but has no slots for O2 sensors:



How could it be?!

Tranny is 4.44:


Is this from Legacy turbo?

I compared ECU`s:


This have RD7 code, mine old has different, RC7 or something like that, i dont remember exactly..

well, the question is - can i replace my old engine with this one, leaving my old harness and ECU with ECUTune stage 1 chip?

Thanks!

The engine should be a straight swap.

The lack of EGR and the missing O2 sensors, is odd as there was an model that had no emission gear on it at all, and ran on leaded gas, still had the converters, but just the honey comb block without the catalyst coating. Was made for the oil producing East.

From my pita exp, don't get water on the engine plugs lol.

The tranny appears to be original to the car - and a VTD type. If you the number you get UK and NZ (!) hits :-)

How did you come up with the idea it's 4.444?

to Tapani:
Previous owner said that the tranny was rebuilt and changed to 4.44.. maybe hes wrong
well, considering number, its 3.71 VTD?

i could count the differentials teeth to be sure?
And will it work with my old USDS TCU with QC?

To Harvey:
So its ok to have no EGR and O2 sensors on it? What to to do with my O2 sensors? plug them or leave unplugged?

Technically it could be rebuilt and just have the 4.44 gears swapped out and still be a vtd.

As far as the 02's if your ecu requires them, run them. I'd imagine youd get better mileage with them than without.

Mate the VTD won't work with the US TCU. You would have to change a lot of gear out of the doner, to fit that box.

Yes it will run without the O2 sensors, but it would be better to fit them.

Thanks Harvey for detailed answer!

I`ve removed the box:






Considering you said and photos, its a Euro box, right?

The ATF was brown, looks very old and bad, im not sure is it burned, it doesnt smell like


The shifter doesnt have power button, so its standard euro i guess

Well, what to do with harness if its euro box? I tried to find here how to, but found nothing
the picture of the connector, the harness comes from plate where shifter cable connected:


Thanks!

It is a euro box. No front speed sensor in the diff casing.

One possibility is to swap the diff casing from the USM 4ACT tranny you have in your car now. You would have to swap the (diff and) crown wheel from the VTD tranny and hope that your pinion will still be at the correct height.... you must check the tooth contact.

See photos attached.
