whats it worth (part II) for an S4 stroker 6.0L

A complete and in good condition S-4 5-speed that will actually pass California smog is a $10-15k car. The Devek stroker is a wildcard factor. If it has another 100k miles in it, it's a plus. Otherwise I have to wait for Thanksgiving and hope that Mark has a good S4 engine on holiday special to drop in. Minus $3.5-5k.
With all the stuff it might need to get it current as far as rubber bits, it's a poster child for dr bob's $5k automatic budget impact. But that's already built into the $10-15k number, so no net impact except on the total budget.
The trashed interior is subjective. I'd need to check with Mark on a used interior. Budget $3k or so?
The lighting fixtures damage is almost expected. The wiring issues are not.
The GTS rear cover on its own isn't a deal breaker, but it is a telltale of a rear impact that deserves serious inspection. Anything showing structural damage/distortion in the body would drop the value a lot, making it uneconomical to buy and restore the car even for extended personal ownership. At least for me...
So, assuming that labor is free and there are no other surprises, I'd probably start the bidding at $5k after satisfactory structural inspection, and set a hard spending limit at about $8-10k, depending on what else it actually needs. That would put the total budget for car and pieces a little under $20k all-in, plus my labor.
*** Note that this is -MY- valuation method. I've purchased or evaluated other 928's (for others) since I bought mine, and tend to have a cynical eye for cars that have extended "recovery" needed. This one does have the 5-speed, but has some driveline and interior cosmetic variables that make a higher valuation tough without confirming what they all might be. YMMV of course.

FYI... the rear bumper was replaced based on a small plastic incident (guy with a trailer hitch backed into the cover punching a hole. no other damage. front bumper just replaced and painted ... also superficial damage as seen by the first pics of a tear in the plastic at the nose.
so, assuming all this, its a $10k car or is a $7k car realistically.
yes, it would take some time to fix the wiring, get that AC working again, and all the little knick nacks that a 25 year old car would have (its an '88 by the way) engine has been running, so that's a good sign and it doesn't burn much oil........ did a Amsoil change a year ago and since then, 5000miles , I think he has added 2 quarts in total. I drove it on and off for a year and it was a good car. perfect transmission

could find out...
no, he bought the car originally in '90 with about 20k miles on it
not much oil consumption. very good
stroker has 100k miles on it, min. maybe a little more.
could find out...
Clear title? Accident history? (why the GTS bumper cover) VIN?
I could swear I remember talking to Susan Thomas about this car, pretty sure it was listed on the Devek website, so that would have been spring 2006. It needed rear interior quarter panels. Maybe the same car, maybe not.
How many miles on the Wiseco pistons with Porsche coating? What's the oil consumption like?

I'd price it the same as I'd price a running, registered, stock '88 5-speed S4.. i.e. based on condition of the interior, exterior, and state of the engine electrics (knock sensors, diagnostic results etc).
Sorry, but the stroker and suspension mods don't make it worth more IMO, if anything it adds a bunch of unknowns. An original numbers-matching same-year car would likely be worth more, as thats what has value in the long-term.
Finger in the air guess is $10-12k on a good day.
The car has electrical issues, needs interior work, has a suspicious GTS rear bumper, and has an engine which has spent a good chunk of its life running badly (see previous threads), so has very unknown condition of engine internals.

This is the only aspect of the description that would cause me enough concern to discount the price.
Mahle Motorsport doesn't even provide pistons with the original "Porsche coating", I would find it difficult to believe that the Weiscos in this motor have the factory coating. That means that the pistons may have whats characterized as "Porsche-like" coating, but I would need to know what the coating is, and be able to inspect its condition.

It would be interesting to see whether one could get a borescope to the skirts either through the filler neck or the drain plug, with a given cylinder at BDC.

That's 50 more than a typical stock S4 5L engine makes. Like any bucket of snakes on a slippery slope, you could get into headers, intake, cams, headwork. Then go after that 100k mile block. Slippery and snakes in the same car!
This car demands an owner who has the time and inclination to finish all the sniggly stuff to make it a reliable and useful car. If there's any time or inclination left after that, go after the potential performance the stroker might offer. Someplace in the middle of all that would be a teardown and inspection. Then WWGBD?

Either I am completely out to lunch or you guys don't read all the posts very carefully.
1989 928 GT: Dunkelblau/black; Devek built 6 Liter engine; SCAT crankshaft; Carillo connecting rods; 968 intake valves; Devek Level 2 headers, X-pipe, and dual exhaust with Borla mufflers; GTS front brakes; Koni shocks with 600#/400# Hyperco springs; and Devek front anti sway bar
So it should have a half decent set of cams also.

You've cut 'n pasted hb253's sig file. The subject of the thread (per Kibort) is an '88.

I refer to the "Devek period" as "The Dark Ages".
While we still work on the same engine and the bores and strokes have not changed much, the pieces, the dimensions, and the technology don't resemble anything that was done back then.
As anyone would expect, in 20 years of progress, the pieces have evolved to the point where reliability is not an issue......here.

The Devek-built engine that I was asking about is the one in my '89GT (the one described in in my signature...). While my obviously personal concern is about my car, I think that the information is relevant to this thread.
Greg's comments about Devek make me somewhat uneasy: while I have not had any engine related problems with the car, I have to wonder what other people's experience has been.
The PO used this car for ORR, but I do not, and do not intend to, race it. I have taken many long trips (Reno, northern CA, LA) without incident. It is a fun car even with the too-loud exhaust and somewhat harsh ride.
Anyway, if Greg, or anyone else, knows of engineering, parts quality or workmanship problems with Devek built motors, I would appreciate hearing of them. I would also like (..and would really prefer..) to hear about stroker engines built by Devek that haven't had any problems too.

I certainly would not worry about it. These engines seemed to either work or not work....and this was evident in the first thousand miles.
You've got a winner!
