Another project, very rare, factory, Quattro coupe. Condition as usual)




dismantle


A 4-cylinder motor was pushed in to deregister, then naturally there will be a 5-cylinder motor.

Inspection of the body showed rust and a lot of putty, then sent the body to sandblasting for cleaning



And there interesting details were revealed


After the sand, immediately the soil


Next - welding, holes in the bottom, new thresholds and arches



the battery was transferred to the trunk

new jacks with emphasis on the side member


Thresholds and arches were stained and oiled before installation





Then the suspension was removed and the bottom was immediately covered with epoxy primer and then with an anti-gravel coating

After the bottom I took up the suspension, everything was disassembled and sent for sandblasting and painting



All consumables are new, the body is on wheels





Then it was necessary to remove the layer of putties and paints that had accumulated over 30 years





After that, everything is immediately put into epoxy and we see such a picture


Further alignment





And priming again




The color will be original LY3D

Looks good so far, thank you for sharing your work with us!

Painting, base as I already wrote LY3D, PPG D800 varnish, paint took 4 liters, varnish 6 liters

I love LY3D...I've had five cars that color.

The assembly began with the laying of fuel and brake lines




The pump suspension with filter is used from b3, because there was no native as well as fasteners on the body


Everything is ready to put the motor.




The state looks so-so, I decided to disassemble it before installation, and for good reason



inside the oil turned into something incomprehensible



As a result, I completely disassembled



New liners ring gaskets





Collected and installed under the hood



Then I installed the rail and pedal assembly


The vacuum amplifier installed a two-membrane from A4, for this I made an adapter for the stem and a flange for fasteners



Then I picked up the back part a little
black vinyl under the number

Looking good, that was some nasty sludge from the 7A!

the motor was lying for a long time, perhaps the oil has oxidized during this time and turned into this

Highly likely that is the case.

Today we will talk about wiring.
In 90% of cases in old cars, it requires repair, after the intervention of music installers, alarms, under the hood, the wires crack from temperature and the ends break off.
Now there will be photos not for the faint of heart)








We managed to get the harness on the buttons in good condition


This heap of wires, extra, from alarms, music and other incomprehensible things


First of all, power wires are laid on the battery in the trunk, starter and generator



grounding




Made a new harness for sensors for tidy, and Headlights, gearbox





Further wiring to the engine. since it is from an audi 90 b3, then I had to unwind the harness, remove or add wires and rewind





ECU installed under the feet of the passenger


After I collected the engine compartment


Checking all systems

I take it you re-wrapped the harnesses after you stripped them down with the cloth/friction tape? Looks nice and factory.

yes, I removed the factory braid, I had to take out extra wires or add somewhere, and then I rewound everything

The longest part of the work is assembly, search or manufacture of fasteners, spare parts, etc.
Drive, there was a replacement of all CV joints and cardan repair



Everything went smoothly at the back, but the front hubs from a4b5 and the shruz ordered from a4b5 did not climb there for some reason, just like the front one from b3 5cyl, as a result, it was possible to pick up by typing, the front one came from b3 4cyl without abs.




Along the way, the oil in the gearbox and gearbox was changed to GL-5 synthetics


Set the brakes by re-drilling the stock discs for 5 bolts


the caliper had to be sharpened in front, so that it would become exactly on the disk, perhaps because of a non-native hub




New hoses and boots for steering rods



The exhaust for the 80 quattro is only from the b3 body, so I had to modify







at the end I welded stainless steel nozzles, made a swing like a drain


Painting of installed elements



The power steering from the 7a motor has a circuit for the brakes, so I took out a plunger and made a new hose to the rail



The filter box has become standard, almost to the factory fasteners


Stove, all elements are new, on top and inside, new seals



In the process, some alterations are solved, such as a clutch rod and other little things



The engine starts, the car drives and slows down, but there are still a lot of problems that we are dealing with.
