Owner's Manuals

An essential item for all 924/944/968 owners, but you'd be amazed at how many of them don't have one. Luckily, you can still get owner's manuals for virtually all 924/944/968 models. The typical cost is $25-$30 each. Rather than exhaustively list each one, go to the suppliers listed below to find the correct version for your car.

Workshop Manuals

Very good but expensive ($200-$500/set) and aimed at the professional mechanic. Unfortunately, it seems that Porsche has discontinued these manuals though some suppliers may have “new old stock” (NOS). You'll often find copies (including illegal bootleg versions on CDROM) for sale on eBay.

Porsche organizes its workshop manuals in layers. The workshop manuals for the later cars are built on top of workshop manuals for the earlier cars. The advantage of this method is that Porsche only has to publish information specific to a new model when it comes out. The disadvantage is that owners of later model cars often have to spend a lot of money to get a complete set of workshop manuals for their car.

Here's the list of workshop manuals for the 924/944/968 series of cars:

Alternatives to the Workshop Manuals

If you have a specific job, but you don't want to spend the money for the workshop manuals, you could try one of the following:

Service Information Books

These books typically contain service bulletins not yet included in the workshop manuals (e.g. PCNA Technical Bulletin, Group 4, Number 9303, 09/28/1993 says that new caster eccentrics, rear mounts and nuts must be installed when fitting 17" wheels on a 944). Rather than buy each book separately (more than 20 published), you can buy CDROMs (~$60/each) with the information as follows:

Technical Information Books

These books are printed as an introduction to a new model when it comes to market. They are cheap (~$10/each) and provide interesting background information. The publications of relevance to 924/944/968 owners are:

PET - “Porsche Elektronischen Teilekataloges”

This CDROM database contains the complete parts list with exploded diagrams for all Porsche models going back to the 356. It's only available to Porsche dealers but I wish Porsche would make it available to the public as it's a very useful reference. You'll often find people selling bootleg copies on eBay but you should note that these are illegal to buy or use if you are not a Porsche dealer.
