I've owned an '86 240 for fifteen years, and I'm about to acquire a '93 940 Turbo. Given my knowledge of the 240, I figure that the main thing I'm going to need to learn about is the turbo. I'd appreciate if anyone can shed light on my questions here:

1) I found a chart on the Gothenburg Bible website with a chart of turbo models. It's hard to read but I believe it says the '93 940 has a Mitsubishi TD04H. Is this correct?

2) I've read the Bentley 240 book Turbo chapter, which has a lot of good information, but I'm wondering how well it applies to the '93 940. Can anyone tell me which sections/pages do or don't apply readily? Do the sections regarding intercooling apply to my 940? (I ask since Gothenburg indicates mine is also water-cooled).

3) I've looked briefly at the FAQ, which also appears to have a lot of good information. I understand better however if I can look at line drawings or pictures while trying to understand procedures. Does anyone have drawings or pictures that show/identify the various components of a '93 940 turbo system?

4) From previous posts, I've gathered that short of buying the official Volvo maintenance manuals, the Haynes UK 900 book is the best. Does this book cover my turbo in good detail?

5) Are there "zero-mile" cleaning procedures that I should perform on the turbo when I get it? One old posting referenced the "Oil Return Line O-Ring Leak Repair" in the FAQ; are there others?
