Tuner Tuesday: 1994 Mercedes-Benz SL70 Renntech

If some is good, more is better. A lot of times that is true, sometimes it is not. Thankfully, that saying applies when talking about V12 Mercedes-Benz. One of the most common modifications to the M120 V12 is taking that 6.0 liter and increasing the displacement to a 7.0, 7.2, 7.3 or even crazier 7.4. AMG was known to do this in small batches as well as other aftermarket tuners. One of those aftermarket tuners was Renntech. They would pump these up to 7.0 liters as well as modify other things like camshafts and surrounding parts. The result was somewhere over 500 horsepower and a price tag to make anyone do a double take. Today, we have a one of those 7.0 liter conversions up for sale in Kentucky in this 1994 SL. Even better, there are some AMG goodies on this car as well.

Feature Listing: 1991 BMW 850i MK-Motorsports

They didn’t get many headlines, but this past weekend was a significant one for BMW. At Le Mans, BMW’s M8 GTE didn’t fair all that well – but the company did make a splash by parking a production-ready 8-series outside. Will the new 8-series be impressive on paper and in person? No doubt, but it’s nowhere near as significant a leap as the E31 was from the E24.

The E31 was BMW’s first real attempt at integrating lots of computer designs and controls into one of their road cars. The clean-sheet design resulted in a 2-door grand tourer that shared some visual similarities with the great M1, but stood apart as a more practical cruiser. Unlike the E24, the windows could fully drop, revealing a graceful pillarless design to match the sweeping greenhouse. The sharp nose amazingly hid an even larger motor than its predecessor; in fact, it was basically two conjoined M30s. That configuration certainly has some drawbacks, but there was no denying that the 850i had serious presence and credentials with the M70 V12 kicking out 300 horsepower.

However, BMW softened the character of what potentially could have been a screamer. Many were outfit with 16″ wheels for a better ride and tied to an automatic transmission. This was truly a GT car, and not the supercar slayer that BMW teased with its M8 Concept. You had a few options to remedy this. You could wait and get a later 850CSi, or you could turn to the aftermarket to harden and sharpen your 8. And one of the best places to turn was MK-Motorsport.

Though not as well-known as Alpina or Hartge, MK-Motorsport developed alongside its countrymen and raced them, too. They also created a long list of improvements for various BMW models, including the E31. Without doubt, though, their biggest impact was made with the perfectly styled and sized signature 6-spoke wheel. Outfit on this beautiful Mauritius Blue Metallic 1991, they measure a jaw-dropping 18″ x 11″ wide in the rear – and boy do they fit perfectly. But this 8 is more than just a pretty set of wheels:

Tuner Tuesday: 1986 Mercedes-Benz 560SEC ABC Exclusive

There are cars from the 1980s, then there are cars that are so 1980s that you’d think they are an actual parody of the decade and just dressing up for a 1980s themed party that one of your friends is having on a Saturday night. As you might have noticed, one of these cars is the Mercedes-Benz 560SEC by German tuner ABC Exclusive. ABC Exclusive was one of the many tuners in the 1980s that pumped out crazy creations from workshops in Europe only to fade away after the money dried up only leaving behind a handful of their creations. We actually featured a BMW E24 6-Series a few years ago by them and it was just as outrageous as today’s car. Most of the time, cars like these are in pretty rough shape by now thanks to the liberal use of fiberglass and body filler, but this 1986 seems to have survived the test of time. Now that cars like these are actually old enough to be retro and cool, would you pony up the cash this C126 is expected to bring?

Tuner Tuesday: 1989 Porsche 911 Turbo RAUH-Welt Begriff

I’m not sure I know where to begin. There is A LOT going on with this 911 and, in this case, that’s a good thing. I first saw this 1989 Porsche 911, modified by RAUH-Welt Begriff and Turbo Kraft, on Rennlist near the end of last year. It looked great and I actually thought it might sell pretty quickly even with its very high price. It had all the right attributes to attract the right sort of attention for what is a pretty over-the-top machine. Then I didn’t see it for a while so I thought it had sold. Lo and behold it had not sold so this time I wanted to take a closer look.

RAUH-Welt Begriff can be pretty divisive among 911 enthusiasts. Not only are Akira Nakai’s designs pretty wild, but many of his creations entirely consist of cosmetic modifications. They are cars that hearken back to many of Porsche’s early race cars with huge power, preposterously wide rear fenders, and massive wings all designed to keep the rear tires firmly glued to the ground. That sort of design in a road car isn’t always appealing and when there isn’t enough grunt to back up the looks the appeal is lessened further. However, there are exceptions; there are builds that possess the wildness of RWB’s designs AND the power to go along with it. This RWB is one such machine. The claims: 600 horsepower, 2,400 lbs. I don’t think outright performance will be an issue.

Tuner Tuesday: 1990 Porsche 911 Carrera 4 Cabriolet – Ruf CR4 Conversion

It’s generally safe to say that we all like RUF. Their full builds can be spectacular both in appearance and performance, but almost any RUF to wear the badge, or simply share the name, possesses upgrades that make them very desirable. We very rarely see any related to the 964 so when we do come across one it’s always worthwhile to pause and take a closer look.

This is a 1990 Porsche 911 Carrera 4 Cabriolet that was sent off to RUF for a “full” CR4 conversion perhaps around the year 2000. Like many conversions what exactly is meant by “full” might be a matter of debate, but in this case the engine does appear to have been blueprinted by RUF with horsepower now at 330. That engine likely represents what buyers will care most about. From the documentation it looks like the owners of this car purchased it from RUF in May 2000, but it’s not clear when that means the conversion itself actually occurred. Maybe there is other documentation to support that. It then was imported into the U.S. where it has resided ever since.

Tuner Tuesday: 1989 Brabus 190E 3.6S

Legendary Mercedes-Benz tuner Brabus has put out a lot of great cars over the years. The majority of the time, they build cars that are like throwing a safe off a skyscraper. Big, powerful cars with giant V8s and V12s that do everything really well, but no one would really call them nimble or lightweight. Today’s car, a 1991 190E 3.8S ”Lightweight” for sale in England gives you a bunch of power with a manual transmission which maintaining a lighter feeling car.

Based off a 190E 2.6, the PR man for Brabus commissioned the company to build a lightweight example with minimal creature comforts for street and track use. What they ended up with was a 3.6 liter M103 with all upgraded internals, stiff suspension, sticky tires, a half roll cage and seats that hurt your hips just by looking at them. (More on that later.) Although built in 2008, this W201 kept its 80s styling and design themes while toeing the line between street car and track car. For as complete and nearly flawless as it is, the price is even more amazing.

Tuner Tuesday: 1989 Mercedes-Benz 190E Tommykaira M19

Update 3/6/18 – What appears to be this same car from July 2016 has appeared on San Francisco’s Craigslist with a $15,000 asking price but little more information. Thanks to our reader Jeff for the spot!

The last time you probably heard the term ‘Tommykaira’, it was ripping around a digital racetrack on Gran Turismo in the late 90s. The name Tommy Kaira was legendary in the JDM car scene in the 2000s with heavy hitter Nissan Skylines and even their own car that got them a place in the Gran Turismo video game series. But before becoming all that, they started off by dabbling in the world of Mercedes-Benz. They took the regular W201 190E and W124 300E and added their own speical touches to the engine, suspension, body work and wheels before reselling them to the Japanese market as the Tommykaira M19 and M30E . Very rarely do I see them for sale because of their relatively low production numbers but recently this M19 has come up for sale a few times on eBay in Yokohama, Japan. So let’s take a closer look at this JDM Baby Benz.

Tuner Tuesday: 1987 RUF BTR

The well worn cliche is that power is intoxicating. While typically that expression is used in reference to abuses by individuals it seems no less applicable to cars. Once you get a taste of a level of acceleration, you begin to want more. And more. And maybe even a little more. Thankfully there exist outlets for such desires; builders who are happy to provide you with completely unnecessary levels of power in our continual pursuit of more. Just bring your wallet.

For your Porsche the name nearly synonymous with the need for extra power is RUF. RUF has been in the game for a long time, producing modified Porsches for 40 years. While in many cases these are conversions where the owner buys a 911 and has RUF parts added by an appropriate installer (or by RUF themselves), RUF also has produced their own builds utilizing nothing more than a Porsche chassis. These cars were badged as a RUF rather than a Porsche and come with a RUF VIN. The one we see most commonly and the one that really got the whole thing started is the BTR. Fitted with a 3.4 liter turbocharged flat-6 mated to a 5-speed manual the BTR was a much more powerful version of the 930 capable of outclassing most any production car available at the time. Naturally that extra performance along with their relative rarity makes them a highly sought after commodity. Here we have one such beast: a 1987 RUF BTR, located in Virginia, with 37,472 miles on it.

Tuner Tuesday: 2001 Mercedes-Benz C320 Brabus C3.8S

One thing that I always admired about Mercedes-Benz tuner Brabus is that they weren’t afraid to touch anything. Oldnew, big, and small, they aren’t afraid to put their touches on any product to roll out of Untertürkheim. Today’s car is one of those where I question was it even worth it to spend a ton of money into making something that atleast right now, isn’t all that desirable. This is a 2003 C320 that was converted by Brabus into what they call a C3.8S. As you might have guessed, they took the 3.2 liter M112 V6 and transformed it into a 3.8 liter making around 300 horsepower to the rear wheels. In typical Brabus fashion, the added front and rear bumpers, a new exhaust, some wheels and finished it all off with some interior touches that differed from the standard W203 offering. All of this time and money left you with a 0-60 time of 6.8 seconds. Yeah, not that impressive.

BiChance: 1991 Alpina B10 BiTurbo

Here we are a week after looking at the 1990 Alpina B10 BiTurbo, and by chance, we get to look at a second BiTurbo. Last week’s was seriously suspect; there were alarm bells throughout, as major chassis issues and incongruous details were capped by a seller clearly looking to deceive the market. At first glance, there’s some cause for concern here, too, as we’ll see in a moment. Is this the case of another crestfallen hero, or does this super sedan hold true to its heritage?
