That was the day I bought Chewy. It was a great day!

Chewy got it's name a couple months later on way back from SITM '04. High-speed run up 275-N (metro-Detroit), slow car in the fast lane. German horns didn't cut it, flash the beams... no good. Started bucking the throttle... made some serious noise! Car moved over.
Mutual concensus was the throttle "buck snort" sound like Chewbacca... an angry Chewy. Never had to use the horn again.

Back then, the exhaust system was MSDS headers into a 3 1/2" single... with ONE muffler! ;)

Another blast from the past.... this is the car that got me into 928s.

XLR8928 has a pair of 280zx, ones a turbo I think. Maybe he will post a couple picts.

Years ago I had a 73 240z, AT, or I might not have ever let it go.

Landseer 11-20-2012 01:15 PM

By all means, gotta see the Z cars, let this double as a nostalgia thread!


My HS swim coach had a silver 72 240Z 5 speed.
Slotted mags and loud mufflers
Coolest car I'd ever seen.

From the hood vents, looks like Jim's is also a turbo?

Meanwhile, Fed Ex guy showed up.
Tom and Mark at 928 Intl sent some critical parts for the Bilsteins!

Parts are expensive but beautiful aluminum chunks.
Am planning to melt hard candle wax into the threads to seal the dirt out.

If I can wind these down a tad further, then use the front S4 springs, 3 brown stripes, that are inherently 10 mm shorter than the 3 green stripe incumbents, it MIGHT be low enough. I don't really want to cut a coil off the brown stripers.

Chris for the collars mix some grease and anti seize and smear it on the threads,
also put some on the spring perches where they contact the collars,
You dont really need wax,
once the springs are set they can be left alone,
and if they need to be moved spray some Pb onto them and it will wake up the grease anti seize.

I did that and it attracted a lot of dirt and debris onto the threads, I was starting to wonder if I would have been better off if I didn't do it

I bought the Eibach lowering springs. They don't slam the car and there's probably even enough adjustment to raise it back to stock if you didn't like it. What they did do however is REALLY help the cars handling especially of long sweepers like an exit ramp. The are relatively pretty cheap too

Landseer 11-21-2012 03:16 AM

Maybe I can hybridize using grease/antiseize on most of the threads, then seal the grit out by filling upper and lower edges with candle wax.

Pete, Eibach's will be the immediate next step if this spring / adjuster attempt fails to lower the car. Do you have a recommendation on how to size them and where to buy? I'm shock / spring / wheel / tire illiterate.

Sean, thanks, and please inject any advice, concerns or criticism. Before noon on any given day you probably see more 928 stuff than most of us in 6 months.

I bought mine at 928 int and there was only 1 type of set so it was easy. They had done all the work fitment wise , under.. $300 at the time

oh, the s4 springs actually seemed to raise my car when I did it. Maybe because my car is lighter than an s4. I only drove around the block before I took the suspension out again.

Landseer 11-21-2012 07:07 AM

OK. That changes my plan.

Economy attempt, gonna whack em.
Maybe. Not sure about this.

Landseer 11-21-2012 12:21 PM

For the record: DO NOT whack your springs and expect it to work right.

That is all.

I just put Bilsteins on my '87 S4 with the stock S4 three-brown springs.

To get the front up to correct ride height required 5 full turns of the adjuster from the bottom - which is 7.5mm on the shock body, or about 15mm of actual ride height once settled. I set mine to 175mm front/rear - which is within the factory range.

So the bottom of the range on a bilstein with S4 springs should be around 160mm at the front once fully settled. Given your suspension geometry is exactly the same as an S4 now, those measurements should apply too.

For reference my '87 is a no-sunroof 5-speed - weighs 1480kg's on a scale with 10L of fuel in it and no driver.

(edit: I just changed the values - can't recall whether I adjusted to 170 or 175mm, so I've erred on the high side. I'll see if I can find the notepad I use in the garage as it'll have all my measurements on it - its gone walkabouts. Annoyingly I just had it up in the air (for O2 sensor) so its not settled and I can't just go measure it)

The first car my older Brother Frank restored when he was maybe 17 was a black '72 240Z I loved that car and wanted it. We drove it to 140, remember the wood rimmed steering wheel and cool dash..He brought home a lot of cute girls in that car, one of them wrecked it.

Fixer 11-21-2012 04:14 PM

Here's the first car i restored, i traded a camera for it in Philly it was parked on the street with no top full of leavesEvery panel was badly dented, the color is a VW Porsche color Sea Blue, painted it with laquer. The other pic is of my CA 2002 which my then girlfriend now Wife drove to Sacremento and bought the original orange Ghia for her for $3200 i think in the early 90s. Great cross country trip..FJ40 i restored in 1995, that i should not have sold, needed money though
My 64 Ghia had high compression flowed heads and duel Delortos with headers it was a fast Ghia did 110mph in 4th topped out.

Karman Ghia's, very stylish, and a rare treat to see one on the road! Love those, especially the orange one.

Toyota Jeep, another awesome slightly obscure ride! Wish I had one.


Reassembly has begun. Stuck with old 3 green striped springs. Will deal with ride height at a later date. Used lots of antiseize on adjusters.

Spindles are hung.

Landseer, you will have a 928 that will inhale similar age 911s on the track. Do you plan on any driver ed when done?

Yes, the orange '74 Ghia from Sacramento was all original, i did the motor in that one too, wish i didn't sell all of them and there are more.
That 2002 pictured was all original too, i rebuilt the motor installed a hot cam and side draft webers and header. I later painted it very well
and drove it for a few years until i was hit hard broadside at a Philly intersection by a car running the light. Enter Porsche from that point forward.

Resto pics
east coast cars are a mess, yuk and never again.

I had my eyes checked once and the Doc asked why there was so much rust in my eyes.
