Tuner Tuesday: 1998 BMW M Roadster Dinan S3

Edit 11/3/2017 – I looked at this Dinan modified M Roadster last August, but there was little information and it hung around for quite a while at $25,000. It has now moved on to a new seller who has taken some more photos and raised the price $4,000. After last month claiming it was an ISR3, the seller has confirmed what our comment from Eric indicated – it’s “just” a S3 Roadster. It has about 1,000 more miles since last year but still looks relatively reasonably priced if you like the color combination and gutsy Dinan modifications – Ed

The other day I was talking with my friend about Turner Motorsports. I first met Will Turner when he was a BMWCCA instructor, just trying to establish his business of selling parts on the side. He and his compatriots all sported E30 M3s; this was, after all, the days before the launch of the U.S. E36 M3. Turner managed to parlay early success in a local modification scene outside of Boston into a countrywide business, and after some time in the club race scene he moved into the major leagues. Success against better funded teams was sometimes difficult, but today Turner is still alive and very much kicking, having become one of the two defacto factory-backed teams running the M6 GT3. To get to that point of factory involvement is an arduous journey to say the least, and few who start out make it.

One other who did was Steve Dinan, who took a niche tuning business from the 1980s into a factory option today. You can walk down to your dealer and order up a fully backed, Dinan modified car. That took a tremendous amount of work and is a testament to the quality of the products on offer from Dinan. They truly take the well-engineered BMWs to the next level, but modifying them to do so can be quite pricey. Take today’s M Roadster, for example. While it wasn’t exactly a cheap car to begin with, with entry level prices in 1998 starting around $42,000. This M Roadster, though, went on to get a further $36,000 in modifications from Dinan:

GCFSB Alumni: 2001 BMW 325i Touring

s-l1600 (6)

Edit 10/01/2017: After fixing a few more things and covering about 10,000 more miles, the buyer of this unique 325iT has it back on the block again in a no reserve auction. – Ed

The E46 wagon has emerged as perhaps the last bastion of good, clean, simple German longroofing. Modern wagons are bulbous, overstuffed with features, and crazy expensive. The biggest options on today’s 325i Touring are color choices, while the mechanicals and general usability remain refreshingly simple: no sunroof, inline-6, 5-speed manual, manual seats. Manual, but in Tanin red leather, just the kind of curveball reader/seller Rob clearly likes. A nice, plain white exterior? Why not add discreet M-pinstriping and anything-but-discreet Creamsicle Orange lower valences? The 7-spoke Style 4s are nice but plain – leave them for the all-season tires and you get summer-rubber on blackened Style 68s! The colors may jump all over the place, but if anything they draw attention to a sweet car that represents a simplicity we have all but lost.

1981 BMW M1

There are a few strange similarities between yesterday’s 1987 Volkswagen Scirocco 16V and today’s subject – the much more elusive and legendary BMW M1. Both were sporty cars developed from more pedestrian beginnings. Both featured high-revving dual-overhead cam motors. But the interesting part comes in the sublet of construction, and the design. Both have links to Giugiaro, but both also borrowed heavily from other designs.

In an article I penned for The Truth About Cars last year, I covered some of the development of the Wedge Era and how those spectacular show car designs channeled their design language down to more pedestrian models. One of the stars of that article were the cutting-edge looks from Giugiaro’s ItalDesign – the firm, and man, responsible for some of your favorites such as the basic shape for the Audi Quattro. But while the Quattro launched its brand into the luxury realm and redefined the 80s, the undisputed German star of the wedgey wonders was the BMW M1.

Tuner Tuesday Double Take: 2002 and 2003 BMW M5 Dinan S2s

There are a few select automotive tuners who can take an impressive package and refine it into an even better entity. That group includes legends such as AMG, Alpina and Ruf – all of which are staples of this segment.

Yet they are far from alone. Given the task of improving on what is generally considered to be one of the greatest sedans ever made is no small feat, but if there was one group up to it, it was Steve Dinan’s eponymous company in California.

While just about anyone can take a turbocharged engine and crank up the boost, slap a few stickers on it and call it done, the E39 M5 didn’t come with forced induction. On top of that, it was a motor which wasn’t exactly underdeveloped before it went into production. Nor were the brakes, suspension, or any other aspect of the third gen M5. But Dinan thought they could improve upon them, and with a tremendous amount of work, did.

Dinan went to town on the S62 from start to end. Out came the factory air boxes, air meters and velocity stacks, replaced by Dinan units of larger diameter and better flow qualities, along with larger throttle bodies bored out by the company. This necessitated reprogramming of the computer controls for the engine to match the new flow characteristics. To help the exhaust side of the motor, unique tubular headers were fit to a free-flowing, lightweight exhaust system. While this sounds a bit like old-school engineering, it was successful; the result was an additional 76 horsepower and 51 lb.ft of torque – basically, this was like adding a 1980 Rabbit’s worth of power to an already powerful car.

Dinan coupled the engine mods with a shorter final drive and higher rev-limiter to reach fantastic speeds. The S2 was capable of 0-60 runs around 4 seconds flat and, in unrestricted mode, geared out around 190 mph in 6th. These are still very impressive numbers today, some fifteen years after its introduction! Of course, special forged wheels from the company were added along with their signature suspension. The price was steep, at $36,000 in modifications alone – a further 50% premium on your premium sedan.

Today, you can pick up one of these super-saloons for less than what the price of the modifications cost originally making them one heck of a performance bargain, and I have two to consider for today’s Tuner Tuesday:

Feature Listing: 1997 BMW 328is

For the 1996 model year, BMW replaced the 325 with the lightly revised 328 model. Power was up with the new M52B28, good for 190 horsepower and 210 lb.ft of torque. Although the new motor represented only a 1 horsepower net gain, there was now 15% more torque and a broader, more usable power band with the M52. That change alone was enough to slash the best part of a second off the 0-60 time, which now came in 7.3 rather than 8 seconds. The motor was much more than just an increase in displacement; lighter internals, revised intake and exhaust and dual oxygen sensors meant it was more efficient and smoother, too. New wheels, body-color lower moldings and revised kidneys were met with, amazingly, a lower price point as the base price of the 328 coupe fell a little over $500 to approximately $33,000.

‘Meet the new Boss’ continued to be the theme for the 3-series then, which remained the benchmark by which all others were judged. Car and Driver pronounced the chassis as “the definitive sports sedan” and the 328 and M3 models continued their dominance of the magazine’s perennial 10 Best list. That this proclamation came from notorious Bavarian-leaning C&D is perhaps no surprise, but what may shock some is that the 3-series didn’t appear as a winner until the E36 chassis in 1992, while it would go on to place an astonishing and unmatched 22 times.

Yet despite their prowess, we tend to only focus on one model in the range – the M3. Perhaps that’s because of their prolific production, perhaps because of their relative affordability; likely we just take it for granted because the 3-series seems to be ageless in its competency. Certainly, it’s an injustice to the normal 325/328 models, in their own right an excellent choice for enthusiasts. So it was with a big grin that this lovely example of the Coupe came across our feed:
