Porsche 924 Turbo Rebuild Continues

by | Feb 22, 2016 | Classic Porsche Blog, Project Cars

I’ve been pushing myself to keep the Porsche 924 Turbo post-paint rebuild progress going. Really I am working on stuff that doesn’t involve ordering the numerous replacement body seals this car is crying out for, but sooner or later I’m going to have to bite the £500 bullet.

In the meantime, I have been ordering cheaper stuff, like contact adhesive, bulldog clips and clamps to help re-stick some trim, including headlining and B-post interior vinyl (below), as well as the rear side panel coverings. I had hoped to just re-stick those and button up refitting the side windows, but of course taking the side panels off exposed cheap speakers, which have been hacked into the metalwork, so I have to sort those out first.

Really I have stripped a load more of the car along the way: doors, trunk and rear seats etc. I have two other complete interiors which I could use, but I’d like to keep as much of the original trim as possible in the 924, so I am trying to give it all a bit of a lift instead. The trunk/boot is completely stripped now for a good clean before that all goes back together. I have heat-gunned off some crappy sound deadening in the deep rear sides and that looks better. I will replace the failed sound deadening with Dynamat Extreme – I still have loads of that around from my hifi fitting days, so it will go to good use in the 924.

First port of call for the Dynamat was in the centre console. This was looking decidely tired with the dried up internal foam sound deadening falling apart and crumbling all over the carpet, so I heat-gunned that off and replaced it all with Dynamat, which will deaden any rattles with some foam glued on top. I had already ordered a bit of spray-on carpet dye, so I cleaned the console up and applied that, working it in by hand. I was pleased with the results:

Looks even better in person than in my iPhone pics. Only downside is it makes the carpet pile quite stiff, but that eases with a bit of a going-over with a vacuum cleaner. I dyed the gearshift carpet surround also and have ordered a new leather gaiter for the dog leg shifter. I also stripped the faces off all the clocks including the centre console auxiliary gauges and cleaned the glass inside – made a big difference to the look. The fascia for the clocks has three 1980s alarm LED holes drilled into it, so I have scrapped that and bought an undrilled one on eBay – £18 delivered. Waiting for that at the mo.

I had an old Toronto SQR48 head unit put aside to fit but a bench test showed the output stage is blown so no sound to the speakers. I’m torn between fitting a modern, clean-looking Bluetooth/iPod head unit or going back to eBay and looking for something more period. It is not a high quality hifi setup in this car, as I am leaving the flat door panels uncut, so I will probably stay with period.

I am also changing all the locks to get a single matching key sorted. The ignition switch created a problem as this steering column top set is a four-screw column switch setup and my other spares are both three-screws, so I couldn’t just bolt a complete new assembly in (different switches and wiring etc). Anyway, I worked through a Rennlist 924 lock change guide and went like a dream with cobalt drill bits. Downside is I now need a four-screw column shroud as the old one was missing a bit. Typical old Italian car thing – like the cigarette burns in various places around the driver’s seat.

What’s next? Well, the wheels are off, I stripped the crappy old tyres on Saturday and will have the new Bridgestone rubber fitted this week. I was going to refurb the wheels beforehand but decided against that for now as I want to get this MOT’d (safety inspected) soon. With the car up on axle stands, I have been thinking about dropping the front crossmember and suspension wishbones off for blasting and a repaint. All that surface corrosion on my nice clean 924 bothers me.

The steering wheel needs a re-trim (or at least a re-stitch), but then I have a Momo 924 boss and nice old 1983 Prototipo from my 911. Maybe they should go on. The doors are being rebuilt internally with stripped and regreased handles and window regulators. Really I could do with adding some sort of remote central locking, but I have to keep remembering I’ll be selling this car when it’s done, so the new owner after me can take it to whatever the next level is (I will probably still do the central locking).

I bought a new bonnet badge for it and need to order some body decals too – probably just the long ‘Porsche’ one under the rear lights. It looks good with just the simple silver lines as per the early press pics.
