Recommissioning a 928 S2

I thought I'd say hello and try and dip into a little bit of knowledge and experience.
I'm just about to start getting ready to get my S2 back on the road. I bought it in June and it had been in storage for about 10 years so needs a full recommissioning to get her back on the road.
My plan is a complete fluid change for everything, rear diff, gearbox, coolant etc and a major service - belts, water pump etc and then probably replace all the shocks and bushes and brand new tyres and then getting her MOT'd and ready for spring.
Firstly, does anybody know of a good downloadable set of instructions for the belts and pulleys so I can get that sorted quite quickly and, apart from the obvious things that need doing, is there anything else I should consider on the S2 - anything quirky about them?

    First I would suggest you get onto the 928UK email list, there are a lot more people there than on here.
    Workshop manuals are available in pdf format for download, don't know where, google it.
    Fluid changes yes, water pump and timing belt, does it need them?
    Shocks and bushes, check them before wasting money, bushes often are okay, shocks only wear out with use.
    Consider replacing rubber hoses too, and check the fuel lines for rust.
    The quirk of the S2 is the siamesed distributor,s it has a little toothed belt inside which does deteriorate over time.

    Cheers. As it's been stood for so long, the belts and pump will done so I know everything is spot on before I start using it. Also, I'm guessing the shocks will be original so after 30 years, they could probably do with replacing?
    I'd never heard of the toothed belt on the distributor - every day is a school day!

    I would say that shocks wear out with use, not age, so it really depends on the mileage whether they will need replacing. Same goes from the water pump, usually good for 100,000 miles as long as the coolant has been changed frequently enough. If the coolant hasn't been changed frequently enough, you could have head gasket problem, and if really bad there could be corrosion to the top of the block, so there is a case for getting the engine running first, before deciding what to do, but you don't want to risk running with a timing belt which is at all suspect (S2s are interference engines). Assuming you don't have any history, you can have a look at the timing belt for any signs of wear or age, but I have seen timing belts that have done 60,000 miles and you can still read the writing on the back. I have seen timing belts that were loose that have wrecked the pulley teeth, and severely weakened the belt.
    Let me know if you know the mileage or any other service history.
