Backdated 1982 SC too 1973 RS

[Andreas Johnsen]

This is my first Porsche and my first post on the forum.
I bought a 1980 911 SC of a guy that sold it through this forum.

1980 911sc coupe for sale

It then got sent to my father Stein Johnsen how has spent a lot of hours on this forum for some time now. I asked him to build the car for me as he has been at it for the last 27 years (in some of the pics you will see his yellow 68 R “not the real thing” )

We decided to build the car as close/correct to a RS as we could although we have had to make budget orientated cuts so itīs not a clone or a replica itīs my car the way I would have built it ….for Porsche☺

You can see a few pictures in the classified ad that the ink goīs to, the following pictures are of the car after we received it and started the transformation.

This is the car before

We knew that the gearbox needed attention with weak syncros but a short test drive reviled a knocking sound and an alarming low oil pressure.

After teardown of the gearbox we found that 4 syncros and two sliders needed to be changed .
Apart from the parts we knew were "tired " the gearbox was in excellent condition.
Very clean inside .
The clutch was new according to the seller but must have been very bad quality as it was on its last legs .
A new Sachs plate was sourced.

Unfortunately the engine had several issues .

The oil pump was very worn and so was the crank !!! I guess that goes hand in hand

The knocking noice were rod bearings that was toast !!!

Not a pleasant surprise !! Then of course the saying "when you are in there started !!

New oil pump, new crank 0/0,all new old stock bearings ,new chains and new piston rings .
The pistons / cylinders /heads/valves/camshaft and rods were ,in excellent condition .

While we were waiting for engine and gearbox parts we pulled the car apart.

After the teardown we found the only real rust on the car...three spots on a 34 year old.







taken care of.

I just had to....the future to come.

The window frame teardown.
Removing the black paint from the frames was a lot of work and very time consuming too. I think the car just looks cheap if the black trim is still black on a backdate and considering the price of second hand or new ...paint remover wins every time.

Before paint we fixed all the old dings and welded the antennae hole on the front fender.



Closer to paint





Primed up and ready.

Very nice! It appears you're making nice progress. I'm doing the same thing now with a 76 shell.

And you're right, taking the trim from Black to Bright and shiny is an obscene amount of work if you do it yourself. I also agree 1000% that it should be a requirement on a a backdate.

What color are you going with for the body?

Cknaak thanks for the kind words, the 1000% made me laugh but Iīm with you there. Old Porscheīs had shiny bits and I would have payed for them if we had not been able to remove the paint

Itīs going from " white whale to black duck tail " with black interior, the rims will have the center painted black too and i was thinking grey for the "stickers" however Iīm still not sure about that maybe a different tone of black to "ghost" the car a bit, we will see.

Wow are the TS housings from scratch or did you section in old ones? Amazing work.

Those very dark greens, that look like black, are very stylish
