I am confused (not a first); can this be used with both an 87-90 and also a 91-95 with the higher output PS Pump?

Correct because probably all they were insuring was an average 928 and that is what the premiums were based on. So yes getting more is ALWAYS a challenge after the fact.

Michael-

Greg makes two different rebuilt lines, using the metal pipes and banjo ends of the originals. As you can see in the pic, the metal end closer to the rack is different between 87-90 and 91-95 (different positioning of the bracket that holds the pressure and return lines to the frame rail), and the latter hose has the restrictor in its midportion.

The picture I posted is the old factory pressure hose from my '93, illustrating the '91-95 hose, and Greg's rebuilt hose is the fitment for '87-90. I was going to use it on the Zombie, which is an '88, but then decided to continue to use the electric power steering setup.

Hilton, it's interesting you mention the spacer donut, that sucker is tight on Greg's line- not sure how he even got it there....

Yesterday finished my rebuild of the power steering lines. I think they have been changed at some point (or car has not been driven much) as they looked in good shape, no cracks or melted (?) stuff found.

So I did not replace them, instead I put on these: http://www.thermotec.com/products/14...mo-sleeve.html to both lines that run near exhaust manifold. I used the 1 1/2" version.

Things to notice:
- you cannot use the std. seating clamp of the pipes, you need to be creative there. What I did I left out the plastic and wrapped Thermotec's around the pipe. Finally I put in the metal clamp and screw'd it in - seems to do the trick.
- Thermotec comes as 12ft (3.6m) or 90cm lengths. Both work, 90cm is actually more than enough for each line.
- That large rubber on the pressure pipe won't go through 1 1/2" hose so I removed it and put it on back on top of Thermotec.
- I put the sleeves all the way from connection to the end. The effort is minimal compared to having it half-cut...

Unfortunately my camera was not at garage. I'll try to get pictures of the installation later.

This case has sort of happy ending after all. Insurance company paid well enough and owner can keep the car. It will very likely live on as full track car as engine internals can be saved.

Owner just returned from Sweden with 100k km's driven '93 manual GTS. Its way too good for track duty. Option list is long but most is normal stuff in any GTS.

M28.49
G28.57

I239 Change of manufacturer of tyre installed on the production line (not customer selectable)
I327 Blaupunkt Köln radio

M423 Cassette container and coin box

M499 Version for West Germany

M650 Sunroof

Front seat centers look like they are from period 911 or 968. Did GTS get those in sport seats or should they be same deeper design as in earlier seats? Other than that seats look like they should so this can be from factory.

This is how burned GTS looked like once fire was put out. It used to be midnight blue.

Erkka:

The seats in the GTS are not 928 seats. There was never a factory option to order 964 seats for the 928.

That charbroiled one has an interesting intake - what's the story behind it?

Reads like a seriously dedicated project car, both financially and personal time.

Maybe a good case for thermal coating the headers?

Any kind of covering on the pressure lines that inhibits inspection is a bad idea IMHO.

I thought so also but this one is so original its hard to believe anything has been changed in it.

Owners has build all kinds of stuff for it. Intake was done by him after measurements said stock intake was severely limiting hp. It looks like even it can be saved. We'll find out eventually how much it makes in dyno. Tuning was almost completely done and ready to go on rollers when fire happened. I bet most Greg Brown strokers do not make as much hp and tq.

In all that car had lots of very interesting things done to it. Carbon fibre brakes for example required almost complete front hub re-engineering. How many 928's in the world have 350mm carbon brakes? Any other around anywhere besides this charbroiled one?

I think a fireproof sleeve is a good idea - just make sure the low-point is away from anything hot, and has a hole so it leaves a mess on the garage floor if it leaks

Threads like this make me feel lucky - 5 years ago I parked my 89 after a short drive with clouds of smoke coming out of the front-left engine bay, it was my PS line, leaking from inside the factory sleeve and dribbling onto the manifolds. No fire, and I drove home with the PS pump belt cut.

Is the right seat also heating?
If not, I suspect the seats are factory. How are the back seats?

What a shame. Any before pics ? Thermo-Tec heat sleeves on the Just Peachy build. Great thought Hilton regarding leaving a hole in the low point of the sleeves.www.thermo-tec.com T

Both have heat. Rears are normal 928 like one would expect. If there were any difference compared to these codes I wouldn't even ask but everything looks original, there is full service book etc.

I have missed the heating right seat code, sorry.
The seats are certainly original then, even if unusual.
The first owner maybe preferred the 964 Turbo seats.
No 09991 option code?
