Tuner Tuesday: 1986 Porsche 930/DP 935 – REVISIT

Darth Vader, your car has arrived. One of my favorite cars that I wrote up for “Tuner Tuesday” was the crazy all-black DP935 back in August. The car has moved sellers and is now available on Ebay. A reserve auction this time around, the opening bid price has climbed with reserve still on from the original $109,500 to $124,900. While there are much better photos of the car this time around, nothing else appears to have changed making those some pretty pricey pictures. Still, this is a fun car to look at, so enjoy the darkness!

Tuner Tuesday: 1983 Mercedes-Benz 500SEC AMG

About a month ago I wrote up a AMG-modified grey market 500SEC that scared people with it’s chromed Pentas, blacked out windows and questionable history. But perhaps if you can get by the again all-caps ad copy, this cranberry-colored grey market 1983 will be the one for you. Sporting the requisite AMG bits and period correct color-matched wheels, this 500SEC certainly looks the part – and the Moby Dick sized stack of receipts may mean this is the not-so-white whale you’ve been looking for:

Tuner Tuesday: 1980 Porsche 928 Euro Gemballa

In the crazy world of Euro tuners, Gemballa stands out for some pretty crazy modifications that are sometimes in questionable taste. But in the 1980s you couldn’t flare a car enough, and Gemballa was one of the best. Gemballa actually made several different body kits for the 928, with seemingly few being the same. This particular model sports some of the wider flares and a large enough wing to make your local Lamborghini Countach jealous; mainted in dark blue paint and sitting over some seriously wide BBS wheels it looks ready for a filming session fo the next Rush music video:

1977 Volkswagen Scirocco

In lieu of the normal “Tuner Tuesday” posts, today I decided to write up two home-brew specials in the likeness of many tuners. We started with the 1968 BMW 1600 S14 swap, a rare to see model with some really great looking and fun-increasing modifications. But I think the cake might go to this afternoon’s Christmas Eve special, a 1977 Volkswagen Scirocco that has more period modifications than you’ll usually see – but manages to pull it off really well! That can’t always be said for 1980s-era modifications in general, as quite a few were in questionable taste. That’s part of what makes this Scirocco so special and neat to see, if seeing an old Scirocco wasn’t neat enough. We’ve gotten to see two this week, the all original and mint condition 1981 Scirocco and today’s tuned example:

Tuner Tuesday: 1983 Mercedes-Benz 500SEC AMG

Back in October, I wrote up a Euro-market Mercedes-Benz 380SEC AMG that was a bit of a poser, but in great condition available for a relatively low price. It looks like no one was really interested in that particular model, though, as it still remains available today. Perhaps that’s because it lacked many of the real-deal AMG components; well, to rectify that I enter into evidence Exhibit B. Today’s near twin of that car appears to be the real deal, complete with AMG suspension, ATS “Penta” wheels, the full body kit and some nifty drive line components. With only a few hours left to act, will this period-correct Bahnstormer be the car that you desire? Take a look at all of that white:

It certainly is a lot to take in, but it looks the part for sure. I’m a bit confused by the advertisement; no documentation about the AMG parts – or, importantly, whether this was an AMG-built car or a car assembled from AMG parts, is provided. I would guess that, in part, is why the bidding is so low currently, sitting below $10,000. For that amount, you get the great SEC look in a bit overdone but correct “dipped” white, some fantastic looking wheels and Euro goodies, and a host of AMG upgrades. The package is about as perfectly 80s as you can get, minus Crockett and Tubbs. The white over blue is a nice combination, though I’d probably change the wheel color to either silver or matching white to complete it. I also liked on the 380 how the AMG badge was black – even if it wasn’t correct. These cars aren’t for everyone, but show up to a meet in this and you’re sure to draw an appreciating crowd. What a neat car!

4WD Week Tuner Tuesday: 1986 Audi Quattro Treser Roadster – REVISIT

3Q_800

Back in August, I wrote up a pretty popular and hugely wild Treser Roadster. With such a small market interested in these cars, it’s no wonder that it’s still available today on Ebay.de. Unfortunately, if you were counting pennies last time to make this happen, the currency conversion hasn’t gone your way, because while it’s still priced at 34,999 Euros, that today will cost you about $1,500 more than it did in August. Still, at less than half the price of a decent Sport Quattro this is a pretty unique piece of Audi history and would look great in some snowy shots – any brave souls out there?

-Carter

The below post originally appeared on our site August 20, 2013:

Not satisfied with the already exotic Audi Quattro he had helped to create, Walter Treser went on a mission to take the Quattro to the next step. His cars featured bespoke TRX wheels (the largest available to the mass market at the time), upgraded 250 horsepower engines (more boost – that could never go wrong!), and perhaps the largest chin spoiler fitted to any road car ever. Seriously, this is the Jay Leno of cars. Treser also revised the interior, rear spoiler and rear bumper cover, and for the exclusivity of one of these gems, he upgraded the price tag substantially. For some, even the Treser Quattro wasn’t enough, and for 39 lucky and wealthy individuals who just had to take it to the next level, Walter cooked up one of the stranger conversions ever done to an Audi at that point; he chopped the top and made a folding hardtop. The Treser Roadster marketed for the equivalent of around $125,000 in 1986. Rare doesn’t begin to describe these cars, but every once in a while one pops up for sale, like today’s Pearlesant White Treser in Germany :

If you had to have the ultimate non-Sport Quattro in the 1980s, this was your car. It is over the top in nearly every way. It certainly isn’t to everyone’s taste, but many of the modified cars from the 1980s weren’t. As Rick James said, “Cocaine is a hell of a drug.” Compared to some of the modified Porsches and Mercedes, the Treser cars were downright pedestrian and civilized; but next to the original, this car looks outrageous. Interestingly, I think this car ends up looking more Japanese than German, but to the right buyer, I doubt that would matter.

The car’s condition appears to be good and it’s not surprising that the top is not functioning, but the seller has promised to fix prior to the sale at full amount. Still, like older modified cars, there is a lot to go wrong here, so be prepared for plenty of visits to the mechanic to sort it out. Like the TRX wheeled BMWs, plan on getting different wheels and saving those original Tresers for show only. The driver’s side headlight seems to be at an odd angle, but that could be an easy fix; Pearlesant White is so difficult to color match and that bumper is so rare, I doubt it saw an impact that wouldn’t show in the photos.

Even among the die-hard Audi aficionados, the Treser cars are polarizing. $46,600 is top dollar for a Quattro that isn’t a sport, but these cars are so rare it’s hard to put a value on it. There are very few originals left, and even fewer in Pearlesant white. In comparison to some of the rare convertible Mercedes and Porsches from the 1980s, this isn’t outlandish money, and the Quattro values have steadily been on the rise over the past decade. As a 1986, it’s eligible for import to the U.S. without too much difficulty, so the question is – will you be the only one in the U.S. with one of these cars?

4WD Week Tuner Tuesday: 2005 Audi A3 Abt Sportline

As I said in yesterday’s Coupe Quattro post, there are a lot of fun Audis that never made it to the U.S. Also like the Coupe Quattro, the A3 isn’t high on many enthusiast’s lists because we got some very similar cars here. However, there were some unique A3s produced and tuned in Europe that never made it to these shores, and this must be pretty high on the list. It’s a model that the U.S. didn’t see; a manual 3.2 Quattro S-Line 2-door A3, which was then modified by noted Audi and Volkswagen tuner Abt. Abt has been in the game as long as some of the other big boys, and ran the factory-backed Touring Car efforts with the early TTs – so sufficed to say, they know what they’re doing. That know-how comes with a price though, and Abt cars are known for being pretty pricey out of the box – so not many have been sold. Take a look at this great rarity for sale today in Germany:

Like my complaints about the second generation R32 were answered with the 6-speed second generation TT 3.2, this A3 has the right gearbox and fun motor combination. Normally I’d prefer a 4-door but the lines of the A3 are prettier than the Golf by a long shot, so the coupe still looks great. The Abt kit integrates reasonably well, though I think the rockers and front spoiler are just a little bit too much. I also much prefer the early 90s Speedline-sourced Abt wheels over more recent offerings, but these fit the car period correctly as they should have been. One neat feature I do really like is the quad exhaust; in 3/4 profile the car reminds me a bit of a streamlined M-Coupe, and that’s not a bad thing at all. For about half the going rate of a second generation R32 then, this car sure looks like a lot of fun – but no, you can’t have it here. Das ist streng verboten!

Tuner Tuesday: 1995 Porsche 911 RS Tribute

They say God is in the details, and if that is the truth than this car must certainly be holy. For 993 fans, it may just be the Holy Grail – a car that was never offered in great quantity or in the United States at all. Similar to yesterday’s 993 Carerra RSR, the Supercup version of the car had a roadgoing derivative as well – the Carrera RS and RS Clubsport. While the RS took the normal “add lightness” route, the RS Clubsport was an out-of-the-box race car, replete with roll cage and all amenities removed. Not content that these cars should remain out of U.S. hands, several copies of the RS and RS Clubsport cars have been made, but perhaps none as exacting as today’s Riviera Blue 1995:

1995 Porsche 911 993 Carrera RS Clubsport “Tribute”

The 993 Carrera RS Clubsport is the ultimate of all naturally aspirated air cooled 911′s. There are even fewer Clubsports built by Porsche than the RS it is based off of.

The Porsche 911 Carrera RS Clubsport is a lightweight variant of the Porsche 993 Carrera, and a lighter version of the RS. This RS version in particular is a track-oriented Carrera RS Clubsport with only limited road usability. It features a naturally aspirated 3.8 liter engine with 300 hp. On the outside, it is easily distinguishable by a special non-retractable rear wing, small front splitter and 3-piece 18” aluminum wheels. The headlight washers were also deleted for additional weight savings. On the inside of an original Clubsport, the rear seats were removed, carpet removed, all power functions including radio, power locks, have been removed and two racing seats and flat door panels were installed. Sound proofing was eliminated completely.

The Porsche 911 Carrera RS Clubsport was produced in model year 1995 and 1996. It was street legal in European and many other countries, but was not exported to the US.

This Porsche 993 Carrera RS Clubsport Tribute Re-Creation started off as a base model 993. This vehicle was the perfect candidate to convert into a rare sought after clubsport; the shell / tub is in great condition with no previous repairs or damage.

All parts used on this specific build are all original Porsche parts. Since many items from the 993 RS Clubsport are very hard to find or NLA, tracking them down was not easy. Every bolt, nut, washer, clip, hardware is brand new from Porsche Germany. Not one single component was left used or untouched. The vehicle was completely stripped down and rebuilt new with 0 miles. This vehicle is a rebuilt title due to previous water damage before the build up, the tub is clean with no accident or body damage history, it was never touched. View the project page on our website tunersmotorsports.com to see the before and after including the media blasting process.

The original 993 RS Clubsport was built mostly for track use, and were never imported to the US for street legal use. This RS Clubsport recreation however is intended to be used both on street and track, giving the owner the opportunity to enjoy this vehicle anywhere!

This Clubsport Tribute started off as a clean, base model Porsche 993 Carrera 2 Coupe. The entire vehicle was stripped down to its bare galvanized frame and built from the ground up. All parts on this vehicle are original Porsche Carrera RS parts, giving it a true “tribute” title to it. It took many years to gather all of the original parts from all over the world to complete this vehicle to near exact specifications that the factory would deliver back in 1995. Not one nut, bolt, seal went un-touched. The entire suspension was overhauled with original RS components, JIC Cross RS Coil overs, factory cup adjustable sway bars and every nut and bolt was replaced with factory new. The engine and transmission were reconstructed with new components; the engine built into a 3.8L and the transmission assembled with steel synchronizers, a lightweight flywheel and racing clutch. This RS also sports a super cup exhaust system, custom x-pipe, and original exhaust manifolds modified to eliminate heat exchangers. The brakes were upgraded to the “big reds”, 322mm front and 299mm rear, steel braided lines, cross drilled vented rotors and Pagid pads.

On the exterior of this tribute, the vehicle features a functional original rear plastic wing, original front lower spoiler, original RS side rocker panels, original front aluminum lightweight hood, original lightweight European doors, original lightweight rear thin glass and door windows. The RS Clubsport has been painted Riviera blue, a color from the era, in a single stage paint. The front and rear bumpers were converted to original European with the added original RS front air ducts and clear lenses, and European amber tail lights to compliment the rear. The roof panel was also removed during the build, and a light-weight carbon fiber panel was installed. Take notice as well that this RS has original center lock system installed, with original Speedline cup center lock wheels for Porsche, a rare find.

Getting to the interior of this vehicle; the original RS Clubsport from Porsche came naked, no carpet, no accessories with a full weld-in 6 point roll cage. The roll cage is to near-exact specifications that Matter cages installed into the original vehicles in the 90’s. This RS followed the same concept, but instead it was opted to have a lightweight RS carpet installed for a more “street-able” feel. Two Recaro Pole Position seats with alcantara centers and blue stitched leather match the blue stitched leather center console with original RS 6 speed aluminum and leather shifter and a blue stitched alcantara dashboard. The roof liner and side panels were done in alcantara as well. Vehicle features a completely functional original A/C system for hot climate areas.

This RS Clubsport is as close to an original RS from the time as you can get. The feel, looks and overall quality of the build resembles factory new.

See the entire project build from day 1 to completion here: http://tunersmotorsports.com/?portfolio=1995-porsche-993-rs-clubsport-re-creation

The level of detail on this car is pretty impressive – all OEM parts or at least OEM replicated parts means this was both an extensive and expensive build. I’d recommend visiting the TuneRS Motorsport link to see where the car came from and how it was built; it is certainly impressive. Really the only item which is out of place but not unwelcome are the Supercup-spec center lock wheels. They’re great looking and suit the design perfectly, though the original came with 5-bolt versions of the wheels as seen on the Turbo 3.6 in the U.S.. Price? If you have to ask, it’s going to be a lot, and $145,000 for a 993 generation Porsche sure seems like a lot. However, real RS Clubsports hover in the 180,000 Euro range and getting them to the U.S. would certainly be difficult. Further, though I haven’t priced out the parts listed here my guess is that a solid chunk of the asking price would be eaten up just by ordering them all. Just as with the 4000 Quattro from yesterday, then, you’d probably be silly to try to replicate this vehicle as I’m not sure you’d come out significantly better off for all of your aggravation. That, and this one is achingly beautiful. Hats off to TuneRS for making one heck of a piece of Porsche art.

Tuner Tuesday: BMW Dinan ISR3

Steve Dinan is a wizard at building monster BMWs, and as such managed to make it into the inner-circle as a dealer-approved modifier of BMWs. This extends not only to the base models but also to the already specialized and quick M models. No one who has driven a M Roadster will accuse it of being a slow car, but Dinan took the S52 motor to another level by adding a supercharger and a host of engine and exhaust upgrades to match. But it didn’t just end there; Dinan revised the suspension as well to better suit the increased power and offer more adjustability to the owners of these specialized cars. One aspect that I think is particularly nice about Dinan’s creations is that they often retain the mostly-stock look that makes sleeper performance cars so special. Plop that performance into a M Roadster and you have a ton of top-down fun:

Each Dinan ISR3 conversion began with a new 2000 BMW M Roadster, which was in-turn superbly modified by Dinan in the following ways:

Engine: intercooled supercharged DOHC 24-valve 6-in-line straight six; aluminum block and head, Dinan/Siemens engine-control system with port fuel injection; Vortech helical-cut-gear-driven supercharger for quiet reliability; 10 pounds boost into 10.5:1 compression; 50-state emissions legal. Two different sized compressor bypass valves, one before and one after the intercooler to eliminate low-speed stumble and surging typical
with “high boost” aftermarket supercharger systems. Thermostatically controlled engine oil cooler, enhanced fuel delivery system with larger high-flow fuel injectors. Air filter located outside engine compartment to insure exposure to cool, dense air. Integrated bumper ducting provides ram air effect as road speed increases.

Displacement: 192 cu in, 3152cc
Power (SAE net): 396 bhp @ 6500 rpm
Torque (SAE net): 326 lb-ft @ 5500 rpm

High Flow Throttle Body: Internal diameter of throttle body has been increased for improved airflow. Throttle response is also faster as a result of the modified shape.

High-Flow Air Flow Meter: A larger-diameter air-flow meter is included in order to improve Intake airflow efficiency. The design incorporates a unique “labyrinth” for improved air-flow-meter-voltage stability as well as shielding it from cylinder pulses for a smooth idle and improved peak horsepower.

High Flow Intake Manifold: Polished and ported with larger-diameter intake runners for maximum intake efficiency and resulting power gains.

Engine Management System: The Siemens engine-management system has been programmed for maximum power gains, drive ability, and emissions compliance. System maintains all “On Board Diagnostic”

(OBD II) functions and ignition timing and air/fuel mixtures are optimal throughout the engine’s operating range. VANOS (variable cam timing system) has been reprogrammed for maximum power gains throughout the engine’s operating range.

Free Flow Exhaust: Stainless steel, free-flow mufflers insure that backpressure is kept to a minimum, without creating an unacceptable exhaust note.

Clutch: Stock “dual mass” flywheel and clutch assembly replaced with Dinan Stage 2 Clutch Assembly. Lightweight aluminum flywheel reduces clutch weight by nearly 15 Ibs. or 39%. Clutch clamp pressure increased by 20%.

Transmission: 5-speed manual

3.38:1 Limited-Slip Differential: Final-drive gearing has been lowered from the stock 3.23:1 ratio to compensate for the increased outer diameter of 285/40-17 tires in the rear.

Performance Springs: Increased spring rates and a modestly lower ride height provide greater control and traction in turns.

Moni/Dinan Externally Adjustable Struts and Shocks: Matched with Dinan springs for maximum control. Features custom digressive compression valving for more low-speed shock shaft velocity control, providing greater restriction of camber and toe-angle changes. Front struts are externally adjustable for personalized control of ride quality and handling characteristics

Anti-roll Bars: 22mm front and rear adjustable anti roll bars.

Front Camber Plates: Relocate strut pick-up points for two degrees negative camber in the front, greatly improving turn-in.

Camber Adjustable Rear Subframe: Provides adjustment of camber angles at the rear of the car.

There aren’t many of these little rockets floating around – the original article from 2001 claims that only 50 would be built. With 400 hp on tap, they’re a potent package, too. Of course, that potency cost, and cost dearly; new out the door, these Z M Roadsters boasted price tags in excess of $80,000 if you ticked all the right boxes. Sound like a lot? It was, because shortly after the launch you could get into a 315 hp S54-motored Z M for around $45,000. The question then becomes one of exclusivity; do you want what no one else has? Perhaps, and if that’s the case then this car is a good candidate for you.

Of course, it sure would be nice if the seller provided better pictures and some more information, specifically on the claim that the car is only one of 6 (though, I’m guessing perhaps in that color?). Though it has low miles, no mechanical history is provided of the car. Then there’s the asking price – $50,000, which by my maths will buy you no less than three normal M Roadsters with change left over to spare. Much like last week’s Ruf 3400 I think the asking price is far too high even considering the increase in performance. While I have no doubt the car is quick and rare, I just could never justify that sort of premium for this particular car.

Tuner Tuesday: 2007 Porsche Boxster S Ruf 3400

Without a doubt, Ruf is one of the most popular tuners in the world, but enthusiasts draw a strong line in the sand over what can and should be considered a Ruf automobile. For the most part, their enthusiasm generally falls off once the car in question does not carry an official Ruf vin plate. But are there extenuating circumstances that allow some cars to still be considered from the maker? Maybe you can help decide on today’s 2007 Boxster S, a car sporting $43,000 worth of Ruf modifications and available for sale on Ebay:

Year: 2007
Model: Boxster S
Engine: 3.4 liter supercharged flat-6

CLICK FOR DETAILS: 2007 Porsche Boxster S Ruf 3400 on eBay

Ten years after the Boxster roadster debuted, it continues on as Porsche’s least expensive model, and remains one of the most thrilling cars on the road for the dollar.Two engines are offered, with a horizontally opposed six-cylinder 2.7L engine appearing on the base Boxster and a 3.4L version of the same engine found in the Boxster S. The smaller engine produces 245 horsepower, while the S has 295 horsepower on hand. Both powerplants use VarioCam technology for 2007 to vary both the valve timing and the valve lift on the intake camshaft. The result is increased power and improved fuel efficiency.The base Boxster has a five-speed manual transmission with a manual six-speed optional. The S gets the six-speed standard, and both models can opt for a five-speed Tiptronic transmission with gear selectors mounted behind the steering wheel.A mid-engined design gives the car a low polar moment of inertia, which enables the Boxster to navigate turns with a nimbleness that has to be experienced to be believed. The extra oomph of the S is helpful when putting the power down coming out of the corner, but the basic Boxster is also a highly entertaining and exceptionally capable vehicle.The Boxster is very well equipped, with heated power mirrors, power leather seats, power windows and locks, an alarm system, and automatic climate control. The Boxster S adds heated windshield wiper fluid, aluminum interior trim, and an anti-theft system. Mote importantly, the S has bigger brakes (the same as are found on the 911), dual exhaust, larger wheels, a tuned suspension, and performance tires to help maximize the 3.4L’s ample power.The power cloth top stows quickly, and can be lowered while driving up to 30 mph. Unusual options on the Boxster include adaptive sport seats that adjust the amount of bolster support, an automatic rear spoiler, ceramic brakes, and a fire extinguisher. A host of wheels and color schemes are available, as are more typical luxury items, such as heated seats, enhanced audio systems, xenon headlights, and a navigation system.

2007 Boxster S/Ruf 3400K Ruf Automobile GmbH, located in Pfaffenhausen Germany, is the largest and most respected manufacturer of enhancements for Porsche cars and is recognized as an automobile manufacturer by the German government. Ruf cars are noted for their performance coupled with Porsche factory levels of refinement and reliability. Ruf cars can be purchased as either a Ruf built car, and carry a Ruf VIN or a Porsche can be modified by Ruf in which case it would carry a Porsche VIN. Due to California smog and licensing issues, this 2007 Boxster S/Ruf carries a Porsche VIN. The car was purchased new in August 2007 and shipped to Ruf USA (then in Dallas, Texas) for installation of the Ruf 3400K drivetrain, the Ruf package for the 987 Porsche Cayman/ Boxsters. The modifications include the addition of a supercharger, reduced compression ratio, larger oil cooler and larger coolant radiators. Ruf lists the ouput of the 3400K as 400HP however, a few Ruf employees have indicated that the real output is more like 440 HP. This car sure feels like it! This car has a limited slip differential, Ruf instrumentation, steering wheel, springs, short shifter and other details. The total cost of the Ruf enhancements was $43K. In Porsche’s product offering, the Turbos provide the best straight line performance and the mid engined Boxster/Cayman, the best handling. The Ruf modified Boxster combines the best of both, Turbo levels of straight line performance with Boxster/Cayman handling. Finished in silver with black leather sport seats, this very rare car is in mint condition and was owned from new by a 64 year old Porsche enthusiast. Complete service records are provided. Please send message through ebay for additional pictures and information.

With a healthy bump in power to near-Turbo levels, this supercharged convertible sure should have the go to match the name; but while the car sports a Ruf badge and some of the goodies, a few important details are missing. For example, the 3400K ran a unique and much more aggressive from bumper which mimics it’s bigger brother GT3’s nose. This carries to the back where the Ruf redesigned rear bumper cover is also missing. Critical for me, though, are those missing Ruf alloys, one of the best traits of the breed. They’ve been replaced by some high quality Fikses – which I’m okay with – that are painted black – which I’m not okay with. But, as I’m not likely to buy this car that’s perhaps a bit non-sequitur.

Despite these missing details, the condition of the cars and the lower miles are both as impressive as the performance of these cars. Pricing on a normal Boxster S of this vintage would generally be high 20s to low 30s, and the opening bid on this car is $45,000. Unsurprisingly it’s failed to get much attention at that price point though it’s likely a good deal when you consider the original pricing on the 3400K was north of $100,000. Still, without the Ruf vin and with some key Ruf details missing, it’s just a stealthy and expensive Boxster to me.
