It's a shame, but for the 928 it seems that power adders seriously take away from your chances of selling your 928.

No one would assert that you could get every penny out of them that you put into them (for any 928, but especially for one with mods) but it seems that adding a supercharger or turbocharger puts a serious black mark on the car that most people don't want to take over.

Maybe it's the assumption that the car has been driven harder than your average car, or the fact that the only time you hear about these systems is when there are problems. Maybe the type of person who wants a car with some boost is also the type of person who wants to have done it themselves.

My suggestion for anyone trying to sell a boosted car: Return it to stock and sell the power adder separately.

What do you think?

Mike,

I can't comment specifically on the 928. However, I think any Porsche, any collectible car for that matter, always gets better resale when it is close to stock as possible.

The fact is, why you like, or what I like (and subsequently added for options and modifications) is not necessarily going to be what the potential buyer wants. As a result, recouping even a part of your investment on modifications is difficult (unless you find the perfect buyer looking for the exact same experience you were going for when you did the mods.)

I think keeping all your stock parts is always the way to go and then returning to stock before your sale will most likely guarantee an easier and possibly higher priced sale.

Very good advice and I agree. However, for those that are more knowledgeable, some of these SC'd and TC'd cars are incredible deals

Do cars with stroker motors hold their value better than the boosted variety? They seem to.

IMHO I'd prefer a stroker over a force induction car.

This is why boosted applications that do not make any permanent modifications to the car are so popular. Go back to stock and sell separately. I’m sure Tim and DR’s kit could benefit from a couple of holes added to the car or other modifications. This would remove one of the biggest advantages to those kits (simplicity and remove-ability).

People are usually cautious around modified cars. Performance modifications come with an assumption the car was driven harder than your average stock vehicle.
I know more than a few people that have picked up very modified Corvette’s (C4’s / C5’s) for what a stock one would sell for, if not much less.

There are so few that have any positive history it’s a hard comparison. The last one I remember showing up here did not exactly fly off the shelf (if it sold at all). But to be fair, it was a rough car.

Most people do, problem is the cost / benefit ratio leans towards boost. Let's face it, for what I have into my 81 (including the car) you cannot buy the parts needed for a "good" stroker.

I'm working with a local Ford guru to build a motor for my replica Cobra. My goal, 350-400rwhp and an 8,000rpm rev limit. So far the parts list is around what a good 928 stroker crank costs.

Maybe, but they are still sold for much less than they cost to build.

When selling ANY car it needs to be completely stripped of the personality of the seller no bumper stickers , fuzzy dice , oil change stickers , everything back to just like new !! Even IF the buyer is going to ADD fuzzy dice and bumper stickers they want to BELIEVE that the car is all original and "like new" ... much like selecting a bride

Nice. Jim Bailey: Standup philosopher.

hmm. There's a joke in there about cars that are blown and intended brides that have ...

If I were to ever sell my car, I would put it back to stock (as nightmare-ish as that seems to be) and sell the other bits separately.

The issue with buying a SC'd car for most, is they really don't know what's been done to the car, or if it's going to need a lot of expensive bits in the near future. Further, if they are not a hands-on/DIY owner, I think it's too scary for them to think about bringing a heavily modified car to a mech to have it worked on. So the pool of buyers that are willing to purchase a SC'd/TC'd 928 is very very limited.

However, you have a large pool of potential 928 buyers that are willing to buy 928's at market prices. Since the SC'd/TC'd cars still fall into this pool, the seller will be inundated with offers for NA cars at current market prices, but may get some more play because of the attractiveness of the SCer/TCer - assuming one can revert it back to stock. And to further complicate things, the SC'd/TC'd buyers who know the value of these cars will play off the NA buyers and up the bid slightly to weed out the NA buyers - Thus getting a "good deal." So in the end, I'd estimate the final price ends up being about $1k or so above the NA market.

However, if you put the car back to stock, you should get about market price for NA car. Then if you sold the SC'r/TC'r kit separately, you should be able to re-coop about 50% of new price or better. Or about $3,000~$4,000.

Seems like a no brainer to me.

another big fear to modified cars is the quality of the modifications. Those familiar with the kits for the 928 for the most part know what they are getting into. When you get into custom setups, lord only knows about the quality of the parts or install or what else was hacked to "make it work".

doktor-t

I´d like a complete, used supercharger kit and an LSD for a reasonable price if someone got that lying in the garage or intend to remove that from the car.

When buying parts from abroad I actually prefer to buy slightly used parts of people who can be trusted. It involves to much extra costs when buying from a dealer/manufacturer with taxes, customs and stuff so most things isn´t reasonable to buy new even if its price isn´t that high. Things add up and that´s the sad thing about it.

I absolutely agree. With a lot of these systems, they're practically one-off since each one seems to have it's own hurdles and there isn't really a 'package' that works 100% of the time for any car. If you knew you were getting everything that worked together in a given car, I think it would add to the comfort level of the buyer.

For the person contemplating selling a car that has one of these systems, I think as Andrew said, it's a no brainer. Take it off and sell them separately unless you know someone who's been drooling over your car. The system is worth more out of the car, and the car is worth more without the system.

50+ Murf kits sold and installed disagrees with your statement

Sure the setup is constantly changing / evolving, this is a good thing. We are far better off today with the Shark Tuned system versus how we were controlling fuel / timing. That doesn’t mean the “older” systems are not 100% complete.

The only ones we hear about are the problems. Many do not realize some setups (like Tampa’s and mine) are prototypes.

Mike Frye

That's all I meant. It's not like ordering up some off-the-shelf setup for a 2005 Mustang. And you're not going to find a guy on every other street corner that knows where all the parts go and have some on his shelf for replacement, that's all. Didn't mean to imply that the systems are incomplete, just that they're not all the same.

Not to knock on Tim's setup, but the fact that he encourages the customer to be there to help set it up is a major selling point to some, but a turnoff to another kind of buyer. (not me BTW)
