My '69 912 to 911 Project

[trevorj]

I'm a few months into a long time dream of restoring a classic porsche. I don't know why I haven't been posting my progress here yet, but here goes.

I picked up a '69 912 roller from a fellow pelican user in Seattle this past September. He had driven the 912 for about a year, and then began doing some work to convert it to a 911. It turned out to be one project too many in his garage of cars, so he put it up for sale, and it was exactly what I was looking for.




You can see my progress so far here:

I think I'll begin posting my progress here as well, as I would certainly appreciate all your input.

I'm attempting to blast and epoxy prime all in my little garage. It's proving to be a bit of a challenge. The blasting has been a series of stuff going wrong with the equipment. The gun is prone to clogging either at the tip or at the valve on the pressure pot. The rubber hose has burst a hole in the side a couple of times. I didn't realize I'd wear out tips so quickly on the gun, so that was another trip to the store.

But when it's working, it's working well. I'm through the floor pan, front suspension pan, front wheel wells, and most of the way through the engine bay.

I'm hoping to switch over to priming by mid day.

If you scrape that yellow/green rubberized undercoating before blasting (where you can) it will save you a lot of sandblasting time..

[trevorj]

Yeah, I learned that along the way. I had hand scraped all the undercoating, but there was still a layer of gummy white primer. I had planned to blast a few weeks ago, but it was going so slow, I ended up doing a pass of the entire body with a wire brush on a angle grinder. That got rid of the bulk of it, but there's a few spots I couldn't get into with that big tool.

[Bob Ashlock]

To scrape that undercoating out of tight places, (or for almost anyplace as far as that goes) I found this cheap Harbor Freight tool to be really useful: Oscillating Multifunction Power Tool
There are various shapes and configurations of blades you can attach to this thing. I scraped my floorpans with it and it was able to get into a lot of those nooks and crannies. For $18, maybe worth a try

Looking proper! Thanks for sharing the progress. Keep it updated for us.

Hey Trevor,

While you've got the body upside down like that..... can you confirm if there are 2 fuel lines that run through the main tunnel from the gas tank to the engine bay? I would assume that there would be being common between the 911 and 912, but haven't dug into mine to confirm. I want to add the PMO fuel pressure regulator to mine, but it needs a return fuel line.

Good luck with the project!

69 912 -> 911

[weseeeee]

Great start, it looks like it's pretty solid!

My 69 912 has 1 fuel line but my 70 911E has two.

Keith,

Only one fuel line on this car. Not sure if that's a 912 thing or not.

Well after 3 fairly infuriating days of blasting, I managed to get it cleaned up and primed last night.

The primer went on really well. It's the dupont 2580 with chromate, which came highly recommended.

I'm gonna take a few days to psych myself up to tackle the interior and the front trunk.

Nice start on your project. Will be following with great interest.

Thanks guys - looks like I may have some more detective work to do!

[trevorj]

Does anyone know what these brackets are for on the driver side of the trunk?

This part of the car was dismantled when I bought it, so I'm not sure if I need these or not, or if they can be deleted.

In my '69 912, the two matching mounts are for the fuse boxes. I assume that's where they are mounted in the 911 also, but I don't have one in my garage to look at.

[trevorj]

Ha, I typed 911 but it's is a 912 body. Wishful thinking I guess...
Fuse boxes makes sense. What about the mount on the lower left of the photo?

[Bob Harriman]

Fuse panels top and bottom. The one with the two holes on the left holds the horn relay rubber and I don't recall what the other relay is for. The rubber mounts to the holes and the relay plugs into the rubber. I'll take a photo if you need me to.

[Bob Harriman]

The female relay rubber mounts from behind into the hole and is held in place by a rubber knob on the back that presses into the hole. I removed mine to show the rubber. The relay plugs into the rubber. I think the other is for fog lamps which I don't have so there is one empty hole.

Hope this helps.

[cgarr]

Looking great, as I remember when working on my 69-912 I was never able to find a good wiring diagram showing the 2 fuse box setup it seemed to be a cross between a few years but there are guys here like above that can help.
