Lots of good thoughts in this thread, and they raise another related issue for me.

Andrew mentioned the depreciated value of the cars. It certainly seems to me that the 928 has reached the bottom of it's depreciation cycle, and that we're seeing a really huge gap opening up between the good condition ones and the well-used ones. I wouldn't be surprised if some models (e.g. Andrew's own '91 GT), and of course GTS, are done depreciating altogether and actually remain stable or gain value over the coming years (assuming light use and meticulous care). I've not watched the 928 market for but 2.5 years, so I'm wondering if any of the more experienced have anything to say on this issue?

Jim_H -- thanks for the compliment, James!

You have to decide why you own your 928. If it is for investment purpose, restore it and keep it stock for later sale. If it is for you pleasure, do the mod but realise the payoff is the performance as the best you'll get on resale, in the general market is, the same price as if no mod were done. To the subset that would want this mod, you could probably break even. Most people think the reason your selling a highly modified car is that you've trashed it. But if its done professionally,from a shop with a good rep, an educated buyer would pay more and you might get close to breaking even with your expenses. Look at how many ads state "$5000k of repairs/maintance done". Do you compensate the seller for this, heck no. Same with a track car, usually the buyer gets the better deal as the seller has run out of cash, interest or his wife has run out of patience...just short of finishing the project.
The redemption with this type of mod is purely yours...ego, pleasure, thrills! Otherwise don't do it.

This is probably true. But, I'm not sure I would be too happy with you if I bought your car not knowing it had been supercharged and found out later that it had been. I can see it now......"Hey Joe, isn't that big's old GTS? What happened to the supercharger?"

Your next phone call would probably be from me saying "Pardon me Mr. Bigs, but can we talk about the supercharger that used to be on this GTS?"

I think I would be pretty disappointed and you would join the ranks of the dreaded and despised PO's for not being forthright.

Having said that. I agree with many others here, that I didn't buy a 928 with the thought of resale in mind. I have had at least one in the household since June of 1992. My attitude about them is to drive them for the pleasure they give and when I sell them, anything I get from them is a bonus. I've had my money's worth from their use over a long period of time.

So, my advice is to do what you want to your GTS. As long as it's done well and you take care of it properly, someone will buy it. Will you have to lower the price? Maybe.....it depends on how motivated you are to sell or how much the prospective buyer wants it. But, even if you do have to lower the price, ... so what? You still have had xx number of great years of driving pleasure from the GTS that was just what you wanted. That has to count for something.

Good luck with whichever direction you choose. I know you will make the right choice.

Sorry this got to be so long.

There are a lot of things I never did in my life because they weren't practical, didn't seem sensible or just plain cost money. There never seemed to be time or money to do the things I wanted to do, but there was always time and money to attend a funeral.

Deciding to do things puts too much value on facts that may or may turn out to be true. But I didn't decide to buy a 928, I chose to buy two. What would make you happy? You have the freedom to make a choice. I myself am reserving judgement until I take my first supermodel ride. Then I will choose.

These cars are meant to be driven and enjoyed, that's what I paid for anyway. That said, I'd hesitate to buy a car that had been supercharged because I'd worry that it had been beaten on.

This is somewhat OT, but please bear with me.

What about Thrust Bearing Failure on the automatics. Will forced induction add to the problem, and would you be more/less willing to buy a s/c'ed automatic 928??????

Really interesting post, from my own biased perspective with my own project. That project being a 2 valve 500 hp engine that will look relatively stock, I would hope it would add value along with the addition of other factory modernizing features like the 993 turbo brakes and GT gearbox. A full restoration doesn't hurt either.

I suppose what might help this angle hold some water may be some 1/4 mile times and maybe even a speed record.

The difference with a N/A project is the level of engineering needs to be of a very high order to achieve the same goals, I agree a Devek stroker motor would in my opinion add value. I think any well sorted N/A car capable of 200 MPH deserves respect. The level of finish and the quality of componants is another issue, as is the car these componants are in.

Gretch

I also agree with the assessment. I believe the improvements and modifications, what ever they are, are a write off....and they can even hurt the resale value of the car..........I think you should expect a SC install to at least limit the market for the car....

It is about the same as putting a swimming pool in your back yard.... a lot of money into a big hole in the ground. And when you sell the house it adds little to resale and some people are afraid of having a pool. Turbo John, Herr Kuhn, just sold his 82 ? auto on E-bay with a completely rebuilt engine AND turbo set up for like $9,000. The car was worth maybe $4,000 before the rebuilt engine possibly $5-6,000 with rebuilt engine then with all the turbo work less than $9,000. A couple years ago an automatic S-4 with a half FAST blower from (Colorado ?) sold for a premium of a few thousand the car went to Illinois/Michigan ?? The buyer was quickly ready to dump it when it lost an alternator belt . It later popped up for sale again as I recall . Generally speaking most buyers look for a nice original unmolested factory stock car (better wheels are OK ) even if they intend to modify and run it hard.... there will always be a few with more money than time, patience, or talent who might just step up and pay big money for "special cars" but finding someone who shares the same dream can be difficult. While you might like having your wife be skillfull and talented in bed you may not want to know how she learned that ... same applies to cars

with out cats its takes 20 minutes to release any tension. I released mine 3 days ago and there was a little movement, but honestly no more than i have seen when the car was NA. Just make it part of routine mtc when your under there or each year...more miles you drive proabably twice a year. Dunno? thats what i do.

Herr-Kuhn

It all depends on the buyer. I have no doubt my Callaway could pull down $15,000 perhaps more...mainly because of the condition. It is unmolested and can lay down some power. The 80 Goldmember brought $8,800 and I did have a lot more than that into it. The beauty is in the eye of the beholder, it is that simple.

I do think the GM could have pulled down $10,000-$11,000 with the right tranny out back. Remember, that car also had an S4 interior and wheels so it was not just an ordinary garden variety turd.

The 928 has little value these days anyway, so it is really not worth all that discussion. I would pay more for a properly boosted 928 than a stock one. I believe it to be silly to alter the GTS as the production was limited and ultimately the car will have value. Anything before that is on the list to be "altered".

John please no offense intended but " I have no doubt my Callaway...... because of the condition. It is unmolested " In my opinion ,molested is molested that it was done by Callaway or the Pope makes little difference to me. I believe Porsche never approved of , authorized ,or assisted Callaway to turbo some used cars( he bought them owned them and did what he pleased) . Shows what a huge amount of money earned from golf club sales can accomplish if one wishes. In the "book of 928" Callaway would at best get a footnote. John if you install a dozen S-4 turbo kits you personally would eclipse everything that Callaway ever did with the 928, now that is an interesting thought.

If I were an outsider and heard about a supercharged 928 I would probably presume it's a one-off and avoid it like the plague. But when/if supercharged 928s become more common they may fetch a premium. There's at least one precident - the '94 and later (Mark IV) Toyota Supra. Buyers expected to find them with at least a BPU (basic performance upgrade). Many if not most people in the market for a Supra either wanted a modded car or planned to do it themselves.

IcemanG17

I think only a couple Devek strokers have ever been resold.... The 93 GTS went at a premium....$55K I think....the 85 or 86 was much cheaper, but it was only a 6.0L not a 6.5? Still if you want to build your own stroker....it seems $20K is the minimum investment!!

If you had a 928 "molested" by the Pope you'd be in for some big bucks.

Hell, John Paul's car is probably going to clear $5 MILLION BUCKS for God's sake, and it's only an Escort:
