Hey...I actually like the Gold color....it is totally retro! Red and black...too plain. The Goldmember was build in 1980...I was living in Switzerland then... cruising the alps on the weekends....those were the days when cars that looked just like the Goldmember were cruising on the Autobahns as police cars.

The car looks really nice in person...some of you saw it at SITM....and it sounds wicked...it needs a silencer! This car has made no friends with the Lancer Evo VIIIs or Neon turbos around town. There might even be an angry M3 or two. 50-100 MPH this car is just incredibly fast.

Sleeper look is the best! You roll on the throttle and simply crush the stuffed suit in the M3...that is what it is all about! Turning an otherwise forgotten old car into something more than is ever expected! The real kick in the teeth is the 3-spd auto! It would be bidding much higher with a manual...I told myself I sould have got a 5-speed...I'll never go slushbox again!

I gave a few guys at SITM a ride in the car...unfortunately I could not hook up with MURF...he wanted a ride, but the logistics didn't work out...next year we'll go in my S4 MURF. I'll bring the adult diapers. Dennis told me the car felt every bit as fast as a Euro 4.7...but remember we were at 4,500 ft elevation and I'm running a wide ratio 3-spd turd-box... The turbo can easily make up for lost performance due to altitude...gotta love that little inherent feature!

The S4 twin...it will be a totally new project...new ideas....better...stronger...faster. I'm always in need of a challenge and this is just the project...but I think I'll keep this one for my own use! "We have the technology, we can rebuild him"...but Goldmember MUST go first. No &** reaming but it has to go!

I want this car SO BAD I'm starting to pee gold!

-My second car ever was an '85 VW Scirocco with the rare Legend Turbo option. A dealer installed turbo, this made about 140 hp and was covered under the factory warrantee. My dad bought this car for me since I was 20 at the time, but I paid all the costs of running it.....which included changing out the exhaust "donut" about a dozen times. These were considered factory, since this project was sponsored by Volkswagen of America. There were a total of 54 kits built, and most went on Scirocco's for some reason. The 2100 pound car used a tiny IHI RHB-5 turbo, and accelerated like a bottle rocket. It could hit 60 mph in less than 7 seconds, and it would do 115 mph without much fuss and bother.

-I had no end of knock and ping with that car. I had to add all sorts of crap to the tank to keep that engine alive, and this is with 8.5:1 compression! Looking back, I suspect the waste gate and the boost gauge, since the former was the "button" type, which is notorious for overboosting. The kit was supposed to do 6 psi, but I watched it hit 10 psi while wasting an early '80's Mustang in Vero Beach one morning.

The sound effects and the way that turbo's come on has always appealed to me. The notion of owning something that few other people actually have is also a big attractant. Unlike many people, I don't care what name is on the hood; When Hyundai produces a rare, 50-only run of turbocharged 350 hp Tiburons that give me the exact same driving experience that my 928 does....I'll be first in line!

[I won't sell my 928 though- don't worry!]

Anyway, this car is an absolute BARGAIN. Kuhn put so much effort into that engine that it isn't even funny! I can't believe he's going to let it go for what Ebay will earn him. Total crime!

I'd buy it right now, but I am about to buy a house, and the particular home will require nearly all of my savings. The investment potential is enormous, and the significant other wants it BAD. Which all means that I'm torn apart right now!

N!

I'd love to have the car also. With how much John has put into bulletproofing the engine, it shouldn't be hard to bolt on a pair of K26/6 or even K27/6 turbos and drastically increase the HP safely. Remember, this isn't much less than 2x the displacement of a 951 and is built much stronger internally than most 951s.

Jim Nowak

I agree but he should have done that from the start. He could have upped the price and probably got what he was asking if he had around 450 to 500 RWHP and dyno sheets with his Ebay auction.

You hit the nail on the head as usual.

Herr-Kuhn

Hey...I fully expect this car to sell today! It is just off the reserve price with 2 hours to go. We'll know about the K-26 install as soon as this car is gone and I get under the Callaway. I have two very fresh K-26/6 that will go into the Bastard and onto my new manifolds. The K-24 is a good match because of the 3-spd AT's wide gear ratios. It is not a top HP car, and was never built to be one.

My S4 will be here within 2 weeks...then the games will really begin. Nice 4V heads, 5.0 liters, 320 HP NA...do any of you have any thoughts on how much bottle feeding I should give it? I know over 600 HP will be easy kill with what I'm going to do...but how far shall I push it? My gut tells me to keep it conservative, say 650 crank as to not kill the driveline and have it completely "safe".

FlyingDog

800+ for at least 1 dyno run, but 650-ish for the street.

Like i said before, the pro guys down here built a TT 928 s4 that broke every part in the drive train and a few in the engine.

At 500-600 I would say you should definitely have forged pistons and better rods just to be on the safe side. He told me about where the stock rods give up but I cant remember. Seems like it was around 600-700. When they first built the car they bent the rods and collapsed the pistons on the first run. Sleeved it, put better pistons in it and Carrello rods. Supposedly that engine dynoed at 950 hp.

Next they fried clutches, one after the other. One of their competitors built a 3.6L 750hp 911 for himself and ran a ceramic clutch for over 40k with no problems, so I would say a dual disc ceramic clutch would probably be required for over 600 plus hp. On the flip side from what I have been told the intermediate plate fingers can break at about 600hp.

After they got the clutch solved they started snapping drive shafts. They had a custom shaft built.

After that you can probably guess that they started blowing transaxles. I am not really sure what sort of internals the 928 5speed has, but i wonder if anybody has ever looking into swapping out for 930 gears. The 924 turbo transaxle can handle about 7-800 hp, as it uses 930 parts, but I would assume that 930 internals would not be an easy swap into a 928 gear box if possible at all.

I would hazard a guess and say if you get some forged pistons in it, and run it at 12 psi you should get decent engine life, as long as the fuel and spark are right.

At 16 psi and over you will start having problems, if you drive it hard.

500 should be pretty safe.
600 horsepower would be pushing it.
650 and over and you will start breaking a lot of parts.

Dont get me wrong, I wish someone would build a 900hp 928, but unless you do all the things these pro builders did down here, plus solve the trans problem it wont happen.

HK, that is a sweet engine set-up!

The price on the car would have gone much higher had the interior looked to be the same color. The carpet ,dash and door pannels in the pics look burgandy and the seats brown. Not the best colors to combine with a gold exterior IMHO.

FWIW, BTDT! 20K motor in a 8K chassis! Yea it sucks, but we all have our own crosses....

For a very high HP TT setup the 4 speed auto (built with AMG internals) would last longer than the 5 speed.... Keep in mind the AMG 4 speeds were designed for cars that weighed 1,000lbs+ more than a 928 AND had more HP...typically 500+hp...they have to be strong...good for up to 1000HP I have heard! But thats what a $6K+ transmission gets you!

Auto...no way. I want a manual in this car. I'm thinking 14-16 psig max on the engine, with probably 10 psig under most conditions. The torque is what will break the parts, not the HP numbers.

All someone had to do was offer up another $50.00 and the Gold car would have gone into contract...but like I said I won't just give it away.

I'm having thoughts of parting it out...but that would just be the wrong thing to do now wouldn't it? But honestly...I'd bet I'd make more money on it this way. Motor $X,000, hood $X00, fenders $X00....bla bla bla.

You should have included the Goldmember action figure.....that mistake will haunt you for the rest of your life...

As I told you a long time ago, no one is going to pay for a turbo kit for an OB, unless it is cheaper than the SC kits.

So if you can sell your kit for $4000, you may have a buyer out there.

Then you may be able to sell the engine for what? $3000? Maybe... Maybe not...

And the rest of the parts? Another few thousand...

You'll be lucky to get $10K out of it.

It's going to be hard to get your money out of this venture, and that's just a fact.

I'd just sell it. You will be able to use the money towards your s4 project.

There are people in the 928 community who still are willing to drop $40K on a GTS.
So it is possible that someone might drop $40K for a TT s4. But only if it is a really
sweet car. With really nice paint, a nice interior, etc.. It has to look like a supercar,
and preform like one. People will not pay $16K, or $40K, for a car that looks
dated, and has an ugly interior. People will want perfect paint, and a really
beautiful leather interior. Then you may make money on the s4 turbo project.

The goldmember thing was a cool project, but not really a good business idea...

Sell it and move on.

Imo000

You are not goint ot sell the car cause of a mere $50 difference, but rather do all the work and part it out?

Pating out a car takes months if not years. The chances of finidng the right person for every part that you have is very small. Now imagine all the frustration and work you have ot put in, just cause you can't lower the final price by $50.

I know you don't want to give the car away, but in this case, I don't think you have too much of a choice. Live with the $50 loss and move on to the S4.

Vilhuer

There is some similarities and possibly same parts in 928 and 911 boxes. What exactly I don't know but there is reference in factory documents about sharing parts with G50. In my opinion G28's biggest problem is not gears, it's input shaft. It was beefed up on latest versions but it's shape remained such that it can't be healthy to put big torque through it. Redesign is not easy and cheap. Because of surrounding parts it's almost impossible to fix this without changing just about everything else at same time.

Herr-Kuhn

At $8,600 this car was an absolute bargain. Look at it this way...to touch any decent 928 (and GM is decent) you'll drop $5,000. How much to rebuild, force induce and pull together in terms of time? A $4,000 twin turbo kit to compete with CS would be silly and impossible. Besides, one is an apple the other an orange.

Remember, it is only worth what someone is willing to pay for it. I'm toying with the idea of pulling out the engine to sell and then returning the car to stock and selling it off cheap. A $4,000 Goldmember, stripped of its "gold"!
