Tuner Tuesday: 1993 Mercedes-Benz 500SL RENNtech 6.0 “SLammer”

Since their launch, the R129 Mercedes-Benz SLs have held my attention. Perhaps it’s because I was heading towards driving age when I first got to sit in a then-new 500SL, but regardless of the motivation I really wanted one. My father used to take me to the local Mercedes-Benz dealership in his W113, so even though I was a child who grew up in the 1980s I was never particularly partial to the R107 – and I’m still not. Early Euro-spec cars look nice to me, but for the most part they look a bit too soft and large. So the R129 was a revelation – it looked substantially more sporty and was thanks to a new 5.0 V8 good for 320 horsepower mated to a 5-speed automatic transmission. But for some well-heeled enthusiasts, the $100,000 price tag (in 1993!) wasn’t enough. AMG was in a state of flux in the early 1990s, but there was a new kid in town that was grabbing some serious headlines – RENNtech:

Tuner Tuesday: 1989 Alpina B11 3.5/1

Another week, another Alpina treat from our favorite new tuner seller from Japan. This time, unlike the mostly 5-series based models that have popped up for sale there is a E32 model on offer. The E32 was a big step up in terms of luxury and driving dynamics from the E23, fully modernizing the high end lineup for BMW. As they had with previous models, Alpina immediately had their hand with the new model and breathed their normal aftermarket life into the large executive sedan. That meant a turned up engine good for 250 horsepower (261 without catalyst) although that engine – from the E28 B10 and E30 B6 – was replaced with a 254 horsepower version in 1988 which was shared with the E34 B10 3.5/1. In addition, the normal suspension, wheel and interior treatments were complimented by some minor aerodynamic tweaks and exhaust upgrades to create a decidedly more performance oriented luxury car:

Tuner Tuesday: 2005 Porsche Boxster Ruf 3800S

It seems like I’m often talking about what the best performance deal going in German cars is. That’s partially because I’m not partial to paying the “what’s new” tax on the biggest and baddest new car. Personally, I’d prefer to let someone else take the substantial depreciation hit and when it’s no longer new, swoop in for what’s still (to me) a pretty new car in good shape. The other part, though, is that I’m not flush with cash; perhaps if I had limitless resources I’d be at the Porsche or Audi dealership every other year signing on a new car. Regardless, there’s a huge contingent of our readership that I believe is in a similar situation to me – hence why we tend to look at older, more affordable (most of the time) models that represent good value, performance or collectability for a more modest investment. That brings us to the car at hand; in this post’s case, a 2005 Porsche Boxster. 2005 was early into the 987 production, having replaced the 986 in 2004. By most peoples’ measure, the 987 was a better looking car, mimicking many of the styling cues of the 997 as the 986 had mimicked the 996. Performance was also improved from some new motors, including an upgraded 3.4 liter engine in the S producing nearly 300 horsepower. That motor, however, did not appear until 2007 – meaning the top-tier S model in 2005 still had the 3.2 from the 986 sitting in the middle of the car. That motor was good for 276 horsepower, which by no means was a small amount. For some people it simply wasn’t enough though, and as expected German super-tuner Ruf offered the solution. The modified Boxsters went by the names of their engine displacement; in the 986, there was the 3400S, which was replaced by the 3600S. When Porsche introduced the 987, Ruf responded with the limited run RK Spyder and Coupe with a supercharged 3.8 liter flat six good for an astonishing 440 horsepower. That was in turn replaced by the 3800S, which it still available. With the newest edition of the 3.8 flat six producing over 400 horsepower (more than double what the Boxster had at launch), Ruf turned the entry level Porsche into a supercar killer:

Tuner Tuesday: Dinan-modded 2008 BMW 550i

Perhaps it’s fitting that if you hit the shift key on the keyboard when attempting the M-Stripes in script you get three questions marks. We’ve recently had a few features questioning whether or not you need the ///M Badge on your 5-series; most recently, Paul looked at the E34 lineup with his M5 v. 540i post. The question has remained throughout the various iterations of the 5-series; while there was a pretty big gap in performance between the E28 535is and M5, those gaps have narrowed in subsequent generations. Couple that with the increased costs of ownership of the M-branded 5 and the higher residual value, and there are some good arguments to look at the top-of-the-range normal 5 versus the Motorsports version. When it comes to the E60, that’s especially true in my mind; the M5 had that great screaming V10 motor and many are fitted with the 7-speed break-your-neck-shifting SMG gearbox. Those are great items to have when you don’t have to pay the bills to repair them, but now the best part of a decade on despite the inexpensive entry price for E60 M5s relative to the performance you’d get, they just seem like a nightmare to undertake ownership of. The answer, then, may be to find a lightly warmed over 550i:

Tuner Tuesday: 1996 Porsche 911 Turbo

It is not hugely surprising that the RWB 993 was a bit polarizing; understandable given the now near cult-status of the 993 and the extreme crafting of the body. Today I have a different modified 993 to look at; this time, instead of a Carrera 2 we’re looking at a 911 Turbo that has been externally modified to look like a Ruf but it’s no poser with a claimed 659 rear wheel horsepower. Is this sacrilegious too, or are the modifications just right here?
