Pulled out coolant hoses and fuel lines that where in good shape from storage, cleaned them all, found enough clean hose clamps for everything and installed them.
Pulled the knock sensor and oil pressure switch, cleaned them, painted them and installed them.

Also changed leak locked the turbo inlet fitting (it would sometimes dribble the tiniest amount of oil once and a while but any amount of oil baking under the hood is to much.

Found my box full of timing covers while looking for other stuff (organizing shit while I search through it) so I swapped the lower timing cover.

Pulled the engine harness and grounding harness off the rusted 626, installed aftermarket battery terminals, had to peal the factory connectors off the wires because otherwise they are too short, had to clean the corrosion off them, clean them in acetone, and install them in the stupid crimp bolt battery terminal connectors.

Pulled the clutch master and slave, cleaned and coated the mounting bolts and nuts.
Pulled the starter, cleaned and coated the bolts.
Also coated the intermediate axle bolts.

Then I decided to paint the hydraulic clutch assembly and all 3 axles.

The only things that haven't been coated or painted are the alternator, the starter and the firewall solenoid with 3 vacuum lines (egr).

I will clean the egr solenoid.
The alternator is staying as is.
Hopefully I can find a better looking starter to use.

Found a starter

Pulled the engine and transmission out of the rusted 626, pulled the transmission off and swapped the end cap.

The transmission still looks like crap, I will clean it a bit more.
I found replacement bolts for the cap, transmission mounting and transmission mounts, cleaned and coated them

Old stage 3 clutch and factory tightened flywheel top, replacement stage 4/5 clutch and fidanza flywheel bottom.

Lightened flywheel :

I tried weighing it on the paint scale nextdoor but it only goes up to 7.5 kg / 16.5 lbs, the flywheel weighs more than 16.5 lbs but I'm sure it weighs under 20lbs.
The fidanza with clutch and flywheel bolts:

10.5 lbs.
Ironically the stage 4/5 clutch pressure plate is much thicker and so are the forks, the disk has larger pucks made of sintered steel and the center of the disk is thicker, this clutch assembly is about 15lbs heavier that the stage 3 which kind of defeats the purpose of the aluminum flywheel.
The stage 3 handles all the power this car ever made.
Why use the replacement assembly? It should go in the 89 mx6 gt that currently has a stage 4 and lightened flywheel.
Perhaps when I rebuild the mx6gt next summer I will powdercoat a transmission for the 626 and swap clutches.

Had to disassembled the entire driver axle to change the outer boot, cleaned the transmission again,still looks like crap but whatever.
Had to solder new wires to the safety neutral switch that bolts in the transmission, crimp ne factory style spade connectors...

Just a few motor mount bolts and washers to clean and coat and it's ready to assemble and drop in.
Don't want to take the motor off the stand until I'm ready to install it.

Installed the flywheel and clutch, new release bearing and the transmission.
Turns out I powdercoated a non turbo lower transmission dust shield. The 3 lower bolts don't line up but it seals the bottom of the transmission so it can stay on for now until I get another one powdercoated....
Got the engine in the car bolted to all 4 mounts.

The weight of the engine did not drop the front end as much as I expected but there is still a lot to install in the engine bay, CV-joints, fluids, battery, headlights, wiper reservoir, wire harnesses, intercooler, pipes... I'm guessing about 300 more pounds to add to front end, hopefully this will lower the front end to the correct ride height.
