So... here's the update for October... first up are the heads.I sent them out to a local buddy for a clean-up, grind, surfacing. After a little blasting, he found a
pretty serious crack. Bummer. A little hard to see but starts at 3:00 in the
freeze plug. No problem though, Rennlist comes through and Geo fixed me up with a quick replacement; ran that over the shop and retrieved my small boat anchor. Thanks Gio, $100 for a usable Porsche head - it doesn't get any better than that.
The rest of the engine is coming along. Nothing real major or expensive there
either - just rings, rod bearings and a good cleaning. I've mentally blocked out
how much I paid for gaskets though. Still need to look at the cams and rebuild my tensioner.
Here's a peek at the seats - not sure which way I'm going on the interior, probably just carpet and some basic repairs though. This will be the first car with my own interior work. I bought a nice industrial sewing machine off of CL and have been practicing - a long way to go there grasshoppah.
I spent a couple of hours going over the exhaust - just trying to get another year or two out of this set-up. The somewhat typical broken welds at the Y-pipe. The good part of this is that the breaks leave an easy to re-assemble trail - too bad I lost the photos of my quality welds. And also, a broken bracket behind the muffler, another easy fix. No holes in the muffler but there was a thin spot where I needed to "add" a little steel.
I needed to get the old heater hoses out so while waiting on the new rubber, I did a clean-up and lube of the wiper bushings. And while in the neighborhood, fitted a new blower motor too.
The car may have been neglected but at least the PO didn't do a bunch of hacks. I did find this o2 problem - and worse, they didn't get the grommet back in place, which let a mouse in.

Really, this project is going pretty well. I'm about where I hoped to be and over halfway through my buy-and-build budget of $5000. ...Bruce

when you get to putting in the carpet use the Weldwood cement it will wake up the old stuff you can get it at HD
dont use any of the spray on adhesives they will soon fail

Update is long overdue. Progress is slow and erratic but the engine work is done and aside from some problems with the Paris-Phone alternator its running pretty well. I rebuilt the original alternator but it died again within a few weeks, so dived in for a GM alternator. This car really seems to like a strong alternator.
So anyway, I can finally turn to the scarey part - the interior. I bought some raw carpet (along with some other supplies) and began with laying out the old pieces as patterns for the new replacements. That went pretty well although I underestimated how much I would need - twice. The old stuff was so loaded with dirt, I didn't even want to bring it in the house.
I started with some of the little pieces that have to be glued. That went fine, although this is vinyl backed, not silverknit carpet so it is a little more difficult to form over the edges of things. The clamps saved me.
Next came the part about sewing the binding onto the edges; and that was really the first sewing I have done in a long time. It was slow going but looked so much better than the old carpet. Sewing is really kinda fun once I got the hang of setting up the machine and start to feel myself getting better at it. Here you can see the color difference in the old carpet on the doors and the new stuff.
When I started this, I really wanted to go away from the dark brown but its kinda growing on me now.

Picked up some Clubsports in exchange for some engine work.

Next up, door cards and maybe while I'm in there, I'l take a run at the dreaded problem with the door stay bolts..Bruce

Can anyone suggest some sort of liquid product that I can apply to my pasteboard door cards to re-stiffen them? The front lower corner has gotten wet on one of them and some of the holes around the clips are delaminated (weak). I remember someone mentioning a marine product for this but search is failing me...Bruce

I notice you did not say 928S. It has no rear rubber spoiler and you have the side door bumpers. I have an 83S auto. I quess I was thinking they only sold the S version in the US in 83. But I suppose not. Is the engine spec/suspension the same and the rest just cosmetic differences on the 83 models?
Great job - You certainly went into it whole hog,,,great write up and thanks for keeping another 83 out there. From what I have seen, the 83 has some fairly low production numbers realtively speaking, but for us who are bringing them back, they are simpler and easier to maintain in general.
BTW, I may have missed if you did this later, but I put the new 3 inch Y-pipe from From Roger and a set of used 85/85 exhaust manifolds from 928 MS and it works wonders on the 83 engine...really nice change. And I have not even replaced the cat back part yet.
Continued luck on your transformation!

Wow. Really coming along nicely. Good call on the alternator and I'm coveting your clubsports... Those are staggered right? What sizes are they front and rear? I'm going to try and score a set of those someday. I know there are some rare larger width fronts (8"?) that I'd love to get my hands on...
That is going to be one very fine rehab when you are done! Keep us posted!

CPES-Clear penetrating epoxy sealer available from Jamestown Distirbutors.
Those are staggered right?
Now for the weekend update... got the drivers door apart and my list of parts ordered. Surprisingly, the locks work except for the broken-off ****. Then started looking at the door stay issue. The upper anchor was stripped, got the door off (had to drill 5 of the 6 bolts) and thought about cutting into it but will make a quick run at a Rivet Nut first. The anchors appear to be two small plates that are threaded. Hopefully this will work.
Next went to work on straightening up the rear interior quarters - a little warped from heat. I've pulled some of the leather loose and hoping I can re-secure it once the panels are straight. I have a bunch of clamps on them but if that doesn't work I may try steaming them or somehow getting them wet, then re-clamp.
Also ordered the last of my interior supplies, the seats are pretty scarey for me. I'l have to re-read Dean's thread and then chant: I think I can... I think I can...
I'm going to dump the blond color and use matching dark brown bolsters with a neutral fabric insert. This will be faux vinyl. I know, thats kinda tacky but the old girl will probably never be worth enough to justify better. If it really looks bad I'l call in a pro - whats one more bail out. I also have a set of 944 seats that I could use or maybe practice on or just sell.
PS... evidently the drivers side door stay anchor bracket gasket is NLA - arg. The last time I cut a hand-gasket was 35 years ago. Stay tuned...Bruce

There's rehab for 928 owners? You're backsliding, my friend. But when are the meetings?
Lemme think... Who's the most notorious, multi-car 928 addict. Calls for a poll.

Just a few small but time consuming things to report this week. My interior quarter panel straightening effort inched forward, I have one of them pretty straight and the other will need another session. I'm less sure that I will be able to avoid recovering the whole thing but clinging to hope. Here's what I've done; first, 10 minutes of a wet towel and then 24 hours in clamps. Results are not perfect but much better.
More on this later... then on to the door cards and a dose of Gitrot. It helped but did not make the card as stiff as new. I'm going to have to do a little bit of fiberglass work to repair one leading edge area so more to come there too. Here's a pic though.
And note the screws to bolster the door's pocket.
And then some tinkering with what to do about the speakers, this little 4x6 was found laying loose in the door and that got me thinking...
Here's the new speaker grille material going in and the new speaker mounts that I cut on last years plasma table project.
And finally, here's a little tool I made to "pull" the revitnut fix for my door stay. As soon as the new stay arrives, I'l be able to test its strength, note the hand cut (crude) gasket. If you're new to revitnuts (like me) then here is a better view of how it looks in the hidden area.
Next up is first fitment of my other plasma project - a bracket to support the armrest. Fun stuff...Bruce
