Really? How much are caps and rotors for your car vs a single disti 16V? Plugs wires? Computers? Sensors? Brake rotors? Pads? Chassis to engine clutch hose?

Nice try.

I agree my 81 has L-jet not K-jet.

The knowledge on rennlist just blows my mind

The spreadsheet comes indirectly from someone who works at Porsche's classic department and I therefore never questioned its contents; all info that relates to my 93GTS being accurate. My understanding is that all of this is accurate at the exit gate of the factory in Germany. The only explanation I can offer is that country or regional distributors sometimes adapted cars to the specificities of their respective markets. Maybe this is why you have come across some discrepancies.

Hi all.,
I think it is only fair when I mention that it was I who made that spreadsheet, not someone at Porsche.
The majority of the data came from the Jorg Austin book, spec books and publications. It is a document that is constantly updated, so thank you Erkka and others for your input.
The latest version is available for download from my web at:

Kind regards,
Theo

Thank you Theo for your commitment to the 928

Awesome spreadsheet. Just what I was looking for.
So it is to my understanding then, that all 32Vs are interference, and all US 16Vs are not. And the 16Vs US have only one distributor etc.

The 4 speed auto was introduced in 1983 it looks like?

Thanks TheoJ. Now I know to whom I will give credit. Excellent work.

Erkka, I did adjust the sheet according to your comments. Thanks for the detailed report.
I'm not really trying to put in every little detail per country. Hope you understand.

Some remarks: The 1985 RoW did have a 3-way KAT in the M298/299. Even the techinfo says so.
I'm not 100% sure but the AUS car was rated at RON91 fuel and therefore had less power than the RoW engine.
About 88 units 1992 GTS were built for the US/CDN market in 1992, but were shipped and sold in 1993.
You and I have those for the RoW market I believe.

Okay there are things on a S4 that cost more than a OB 16V (like twice as many valves)....but there are things on the GTS that cost far more than an S4 (PSD, brakes, etc).....

HOWEVER there are things on OB's that are rare or NLA that cost MORE... or are far more difficult to maintain....like the vacuum door locks....

Theres a reason the guideline for 928 ownership is $200 a month for maintenance.....its not like its $150 for OB's $200 for S4's and $300 for GTS's....

My point is ALL 928's cost $$$$ to maintain and drive...in theory the OB's "might" be cheaper due to the lack of computers....but thats about it.....

BTW the spreadsheet RULES.....excellent job!

Has anyone ever seen ROW 16V car with US model engine? From factory obviously and not Japanise model. I suspect no and spec books have wrong info. This versions existence is expecially suspicious as engines with these numbers were not made for USA anymore.

Thats true for '87 and '88 MY. AFAIK for '89 MY fuel code plug was changed to same as rest of the ROW cat models, meaning 320 hp.

They were stamped with '93 P VIN so they really should be called '93 MY cars even though all parts in them are same what was used in '92 ROW models. They were sold starting in January 1992 which is still '92 MY normally.

There isn't one single factory or other source which has nearly everything correct. '78 MY US engine numbers is one good example. Even though Porsche doesn't acnowledge it they really made separate US engines as early as summer '77. US '78 VIN 0016 has M28/03 engine already. Your Excel is very good start for first one though.

Erkka,
I would like to hang on to the Porsche specs as much as possible, and make a comment on things that are peculiar, like the 1992 GTS for the USA/CDN market which were apparently never registered like that. ok?
I changed the 89 AUS car. The techinfo also states only two models, no AUS version. You're right. I also noticed that the 928SE was also sold in small numbers in 1989. I will add that.

I'm still puzzled about the 1985 RoW/US cars. Anyone know this exactly?

If you trust too much on Porsche specs I think it will make list like that less valuable. It has been shown many times that some things that factory is saying simply aren't true. I think whole purpose of such factory independed lists should be to aim for what is actual reality. Meaning what kind of cars were really done each MY.
