Questions about turbo charging an 82 SC RoW before I do a search

[DARISC]

Will you guys please help prepare me to do a search on this topic (or possibly negate my need to do a search) by answering a few questions?

1. What's a ballpark on cost of doing it? I'm mechanically disinclined (Oh, I feel the scorn of some of you already!) - understand theories/principles, but am eligible for a post doc degree in cross threading - therefore I'd be paying my expert Porsche mech/racer ($90/hr shop rate) to do the work.

2. It's my beloved daily driver that I don't track - will I be able to pass smog cert. in CA? If not, no need to read on.

3. If I drive it "sanely" will engine/915 trans life be significantly adversely affected?

4. I've got SSI's w/Dansk dual in/out - any change req'd? I'm lovin' the car as-is (first Porsche as of about a year ago), but the idea of a turbo "slingshot" available under my right foot keeps gnawing at me (memories of my RX7 TT).

5. Will the CIS adjust to handle the boost if not too radical?

6. Assuming I can do this and pass CA smog, will the fact that the RoW engine has 9.8:1 comp. affect it's ability to run on the 91 octane gas in CA?

I don't want to approach my mech. with this until I hear from some of you guys w/turbo'd SCs.

Thanks in advance to any responders!

Naah. I believe it's a bad idea. Being ROW car, it will require lowering of C/R to allow turbocharging. Also, if you cannot wrench you will pay trought your nose and in the end you will havbe unreliable finicky car with weak tranny and small brakes that cost you 1½ more than working 930.

Sell the car and buy 930.

Thanks beepbeep !- I suspected that would be the case - decision made. I appreciate the quick response - saves other well meaners their time!

Will never sell the car, however (+/-40k$ in it) - but a good 930 in addition? Oh yeah!

If you're interested, I got the true skinny as to why Porsche pulled the 930 off the U.S. market back in the day - and it had not to do w/smog or whatever. I've never seen what I know to be the facts in any auto mag. - if you're interested, pm me & I'll peck it out for you - It all happened near where I lived @ the time.

beepbeep - forgot to say, I've been in COMPLETE AWE over your IF2 thread !

Wasn't there a juridical dispute after some lawyers drunk wife crashed in a 930 or something like that?

Anyway, ROW SC isn't a good start for turbocharging. Even if you could wrench yourself, financial break-even would be somewhere around (very)low boost add-on turbo. Everything beyond that is economically unfeasible.

For usable power you would have to change so many things that it would be much cheaper to just sell the car and buy project car that needs the last touch or working 930.

You can turbocharge any internal combustion engine no matter what the compression ratio is, but the higher the mechanical compression is the lower the safe level of boost is. When the CR gets too high you can only run a little bit of boost andthen it isn't worth it.

At this point putting a non-factory turbocharger on a CIS porsche is pretty much a DIY type of deal and requires a bit of tinkering. It isn't a project for someone who isn't really comfortable with turning wrenches.
Paying a professional mechanic to do that will be very expensive as Goran mentioned.

Goran,

Some of the details are foggy in my mind over the years since my ex-wife related the story to me as told to her by a coworker, a professional "expert witness" (not in the automotive field). This was shorly after Porsche pulled the 930 off the market here.

The coworker heard the following story from a speaker at a convention or seminar for professional expert witnesses that he'd attended and told my wife about it because he knew I was into sports cars.

In La Jolla, CA, a neighborhood in San Diego, a woman let her boyfriend drive her 930 (the people are the fuzzy details) who proceeded to kill himself on a city street s-curve.

The lady 930 owner proceeded to sue Porsche.

At some point during the ensuing legal process, Porsche sent a team, including one of their factory test drivers, to La Jolla where they got police permission to block off the streets so the test driver could reenact what the dead driver did (without losing control & killing himself, of course). This to prove, I would assume, that it was driver error rather than any fault of the car that caused the fatality.

On one of several passes that the test driver made, he broke the tail loose and, of course, caught it up - probably an intentional part of his testing and duly noted in the test notes that the Porsche team recorded with typical Germanic attention to detail.

As I recall, both sides had their teams of lawyers traveling back and forth from Germany to California on several occasions during the trial.

As it turned out, American lawyers and Porsche Lawyers/test team were on the same flight back to Germany after the reenactment (to which the American lawers had, of course, not been invited).

Upon landing, both parties deplaned, Germans first. One of the Americans picked up an attache case that one of the Germans had left behind on the plane.

While crossing the tarmac to the terminal, the American lawyer opened the case to see who it belonged to and "happened" to see the test data, including the test driver "losing control".

He caught up with the Germans and returned the case to it's owner, pointing out that he'd had to open it to see whose it was and couldn't help but see while rifleing through the cases contents, that "even your expert test driver lost control I see!" I can picture the sardonic smile on the American lawyer's face as he said this.

According to the speaker at the convention/seminar relating this story, that incident sounded the death knell for Porsche's chances to win the lawsuit and they settled the case and withdrew the 930 from the U.S. market, telling the public, who were unaware of the internal machinations of the law suit, that compliance with the U.S. feds new, more stringent smog laws made it economically unfeasible to modify the 930 to comply.

Ironic, no?

Thanks Goran & Sammyg - It'll stay w/o turbo.

Sorry about the double post.
