Ben's 924S

Postby Grillage » Fri Sep 13, 2019 6:09 pm

Hi all,

I've done it again. I can't stop buying unwanted 80's sports cars (see prior Maserati Biturbo thread)

This time I found a 1987 Porsche 924S on craigslist in Cynthiana KY (about an hour south of me) for $800. Non-running of course. How can I be expected to say no to that?

Anyway, here's what it looked like when I brought it home:
Image
Image
The driver's side had been hit in the door and just behind so the PO put a rattle canned 944 door on
Image

One of the reasons I pulled the trigger is that the nearby pullandpay placed a red 1987 924S (though this was an automatic) the same week I found the one I bought.
Image
I pulled a bunch of stuff over a couple trips
Image
Image
First the good passenger's seat, the door cards, the center console, seat belts, sunroof panel, hood, fuse box, glove box. The door was bad and the hatch was destroyed so I left them.

Then when I went back I pulled the motor complete.
Also the steering wheel which i changed out later
So the interior now looks like so:
Image
Image

Then I went about trying the get the car to start.
The previous owner said that the car had overheated and he thought the head gasket blew. We couldn't get it to start when I picked the car up so I didn't know what to really expect.
After the usual fuel, spark troubleshooting, I narrowed it down to the ECU not sending spark to the plugs. Here's what I found when I pulled the ECU:
Image
Image

The resistor pictured was rattling around in the ECU box - I tried to solder it back in but it still didn't work. Eventually I found a guy on eBay who has a TON of 944 parts - and lives in Piqua OH - about 2 hours north of me.

I ended up with this haul:
Image
A couple Mirrors which I frankensteined into a good one, a new red door, and an ECU.
Here's the new door compared with the old one.
Image
This car was painted in Guards Red - which is like the Porsche version of Tornado Red -- Single Stage! so I was careful about getting body panels that hadn't been repainted and cleared.

I ended up finding the correct decals for the door - the Missing "PORSCHE" and a new non-oxidized "924S" and then I also hit the whole car with polish and compound:

See the line I'm pointing at here? I taped it off to see the difference:
Image
Also the roof - before and after :
Image
There were also a few places where the PO painted over entire body panels with what I think is a paintscratch brand can of matching Guards Red - I sanded through all of that on one fender and got back to original paint.

Looks pretty darn good after!
Image
Image

So I drove the car a bit once it was running and made sure I knew the problems before I spent a bunch of time or money on it.

What it needs:

Motor needs refresh - this one is pissing coolant from somewhere and losing oil. It never really seemed like the head gasket was blown (compression is okay) but it's definitely a worn motor. The odometer shows 116k miles (or maybe 216?) and the timing belt is definitely old.

Transmission - the clutch is on its way out. The symptom from these clutches apparently is that they are super herky jerky when you go on or off throttle. I have that bad.

Electrical - the radio seems to work sometimes, but not always. that's my last priority

So I took the leap and tore down the old motor:
Image
Image

This stuff all arrived today - Rings, Bearings, belts, seals, gaskets, clutch etc.
Image

Oh, and I bought a lift!

Anyway, wish me luck!

Dude! It has Porsche script (/jacquard?) seats! I’ve never seen those. Just the Quattro ones which I always liked .

Paint turned out real good .

Someday I would like to be rolling a car with the Porsche crest on the steering wheel...

The seats are pretty sweet - the "bad" one that I took out really wasn't that bad. Just a cigarette burn in the bottom portion. So I made a gaming setup out of it for F1 2019:

Also, I should mention what the 924 S is.

The 924 stopped being sold in the US after the 944 appeared around 1983. But Porsche brought it back for 1987 and 1988 with the 2.5L 944 engine rather than the audi based 2.0 engine it had early on. It ended up being actually a bit quicker than the 944 due to the difference in weight. It's really a fun little car to drive. The motor is up front but the trans is in the rear - weird setup.

Sweet project! This is already good and only going to get better :)

I've read that the 924 and the B3 Cq's share some common DNA, the mirrors look similar.

Also, jealous about the lift. One day...

Nice to see a 924s being saved and red I've found 90% of the time cleans up really good no matter what brand car its on. Its just keeping it red i've found is a pita.

The porsche jaquard is a really nice trim. Very audi-esque.

I thought about getting an early dash 944 when I was looking but ended up with a later rounded dash 944 that I am currently putting a 2.2 audi turbo engine in. One of the 944's I had in the uk did have an auto box, they are easy to convert over to manual.

Was the guy you got the spares from Mark Pleiman as he is in Ohio and breaks porsche's with a ton of spares?

It was!

He’s a super nice guy on the middle of nowhere!

He and his sons do it

Yeah, thats where my 944 came from. I had some bits turn up recently and deciding what to get next for the car. I ended up getting a rolling shell from him and slowly getting the bits that I need to put it back together.

Made some progress this weekend so far

Got the motor out of the car. I had no real problem pulling the motor out of the junkyard car from the top but this one I couldn’t get that way. Had to drop it out from the bottom and drop subframe, steering rack etc.

I think because of the manual trans on this car has a much different connection to the torque tube than the auto did.
Image
Anyway, here’s the clutch I pulled out. It uses a rubber center to keep shifts smooth - which is great except when they break. This explains the Herky jerky feel when on or off throttle:
Image

The new clutch I bought is sprung rather than the rubber
