Tuner Tuesday: 2006 BMW M5 Dinan 5.8

Nate’s look at the E34 and E39 Dinan M5s over the past week is a poignant reminder of the factory-backed performance available in these super sedans. In the best style of “Q-Ships” – World War II merchant ships that hid surprising armament behind their docile exterior – they’re turned up but never outrageous. When it came to the E60 chassis though, with 500 horsepower on tap how did one increase the already world-beating performance? In Dinan’s case, there was no replacement for displacement, as they punched out the 5 liter V10 to 5.8 liters. The result was an additional 100 horsepower and around 80 lb.ft more torque while still maintaining the stratospheric redline. Yet that insane performance was available in a wrapper which looked no different than a standard M5:

1991 BMW M5 Dinan 3.9 – Revisit


The E34 M5 may be the least-loved of the breed, but who is going to argue with a 3.9 liter stroker S38? I adore my S38B35, and the thought of a torquier, gnarlier Dinanified inline-6 with an extra pint of volume makes me tingle. This Calypso Red M5 has made the rounds, first selling on BaT in 2012 for a relative pittance before spending the last year-plus trying to spin a profit. The speculative seller has repainted it but accrued fewer than 1k miles, making clear his intentions to cash in on a rare, tuned M-car. The reality that E34s aren’t appreciating like E30s or E38s has apparently begun to set in, as he’s asking now asking $6,500 less than in 11/2014. If you’re looking for a monster E34, this is probably the way to go. But when you could be getting an E39 with 60 more horsepower and a generation newer everything, does anyone like the E34 enough to pay the premium? I’m guessing the seller is going to have to have more patience or less pride before this M5 can start spinning its wheels again with a real driver.

Feature Listing: 1999 BMW M Roadster with AC Schnitzer and Dinan Modifications

With all the hoopla surrounding the BMW M Coupe, it’s easy to forget about its sibling, the M Roadster. This wide-hipped roadster offers a lot of power in a very small package along with the ability to drop the top and listen to the noise of that straight six out the quad tailpipes. This Estoril Blue M Roadster is for sale from former GCFSB contributor Aaron Kraljev in Portland, Oregon. This M Roadster was his personal car and has been meticulously maintained. It also comes with a host of nice options and accessories, such as the hardtop, AC Schnitzer alloys and exhaust along with Dinan performance software. Looking to stand out a bit with your M Roadster?

Double Take – Almost M: 2006 and 2008 BMW 550is

It seems that with every progressive generation of BMW 5-series, the gap between the outgoing M5 and the top of the line non-M 5 series narrows considerably. While there wasn’t much of a contest between the E28 M5 and E34 535i, by the end of the E34 run the 540i M Sport was – for all intents and purposes – a M5 without the S38. BMW upped the ante to 400 horsepower in the new E39 M5, once again widening the gap to the 540i model. But the successor E60 545i offered 330 horsepower with matching torque in 2003 alongside the outgoing E39 and once again the gap in performance became much smaller. That gap was made almost impercievable in 2005, when BMW revised the E60 with the increased displacement in the N62 motor. Now sporting 4.8 liters from the N62B48, the new “550i” now had 360 horsepower and 361 lb.ft of torque – a near match for the S62. What was perhaps more amazing was that the new N62 also nearly matched the torque of the new E60 M5’s S85 V10. But while that screaming V10 produced far more horsepower, the peak torque was reached only at 6,100 revolutions – hardly practical in your daily commute. In comparison, peak twist on the N62 came at a much more realistic 3,400 r.p.m.s, and on the fly these 550is were – and still are – seriously quick sedans. They also introduced the next generation of design language and computer technology into the 5-series. Some love the look while others lambaste the design. While it’s certainly not my favorite 5, at least it’s distinctive and different in a world full of cookie-cutter designs and dare I say I think it may look better today than it did new – perhaps a testament to its avant garde lines.…

Tuned BMW E60 M5s

s-l1600 (3)
You might think that a car that has a simple button to raise its power by 100 horses might have enough, but today we have two E60 M5s that will explain to you why that kind of thinking makes you a peacenik ninny. I mean, if you can get a V10 in used Audis, then you have to do something to make your M5 stick out, right? These two E60s take pretty different approaches to power and style – supercharger vs. stroker, manual vs. SMG, Eurotuner vs. Roundel – but both represent about as insane of Autobahn stormers as you can find.

Tuner Tuesday: 1995 BMW 840Ci 6-speed Supercharged

For many, the top dog of the E31 lineup for BMW was the 850CSi. Others will contest that aftermarket tuner Alpina got it just right with their modification of the 850CSi, the B12 5.7 Coupe. Let’s be honest though – great condition examples of those cars are hardly affordable for most, and the exotic performance comes with some potentially costly maintenance on the big V12. But I think our reader John may have spotted the perfect alternative to those cars, and it’s a bit unusual. When BMW launched the 840Ci, I remember initially thinking it was a bit of a letdown. After all, the company was seemingly running away from the signature V12 and replacing it with a smaller and less powerful V8. That, in many ways, doesn’t seem like progress. But the M60 produced 9/10s of the power of the M70, yet was less expensive and got better fuel economy. Of course, unfortunately it was also only available in the U.S. with the 5-speed automatic – and it was a lot less powerful than the CSi model. At least most of them are…

2008 BMW 335i Coupe Dinan

As I look forward to the next few years and what kind of car I might move into next, the BMW 3 series coupe is always up there on the list. This is a car that seemingly has it all, such as practicality, performance and the availability of a manual gearbox, which, sadly seems to be waning with the newer models. There is also a huge aftermarket for these coupes as well, from mild tunes to wild M3 clone iterations. This 335i Coupe for sale from our friends at EuroWerkz has been treated to some Dinan modifications, inclusive of Stage II software and camber plates.

1987 Dinan BMW M6 Turbo

$_57 (1)
With the markets for prime E28 M5s and E24 M6s gaining some steam recently, we’ve seen mid- to low-mileage examples stretching over $30k and sometimes much higher. Today’s is a real monster in just about every way. Under 50k miles and perfect condition make it a high-dollar Shark to start, but this M6 is one of 24 M6s that got the full meal deal from Dinan including a turbo bringing the S38 to a bonkers 460hp and Stage 3 suspension. Black with M-pinstriping on later 17″ Dinan 5 spokes give the aesthetics to back up that this is a Bavarian sledgehammer.

1988 BMW M5

This E28 M5 was the car Dinan used for R&D to create their own modifications to supplement BMW’s upgrades to the platform. Not only does that make it a cool piece of American tuner history, but it clears the air of any pretension or garage-queeniness. This M5 has been used and worked on from the get-go. That makes things like the Euro bumpers, recovered seats (now without heat), and early engine rebuild (likely due to the early testing?) not as big of issues. It’s a very clean and good-looking M5 with a fun – if not flawless – history. Even with over 100k miles and bumper conversions, clean E28 M5s have been garnering some serious attention and money. A colorful but respectful past just seems like more of an excuse to drive a great M5 if you can afford it.

1991 BMW M5

Last week I wrote up a gorgeous E34 540i/6 M-Sport that was listed just below $20k. Seems that most people thought the price on that was too high, despite the low miles and it’s owner being a long time BMW enthusaist. So, when I saw this ’91 M5 on Pelican Parts with a sale price about $2k lower than that of the 540i, I knew I had to write it up. I’m interested to see what ya’ll think of this deal, because while this car has nearly double the miles of the 540i, it has some Dinan bits, and it’s an M5. Is this car really so special that it warrants the price being within a months rent of a 540i with much lower miles?

Yes. Yes it is.

This is the E34 M5 we’re talking about here. This is THE Bimmer of the 90s. I acknowledge how cool the 540i M-Sports are, but I’m an enthusaist, and I’m the target audience for specialty models. The M5 is popular with everyone, and if you’re looking to get into a young timer classic, name recognition is important. There might be more costs upfront but the return on investment will be higher as well. Five or ten years down the road, when you’ve had your fun and are ready for something different, what would you rather be listing, an M5 or a 540i/6 M-Sport? The answer should be M5 every single time, that is if you’re into making some money on the deal. I’m not saying that isn’t possible with the 540i or any other specialty variants that were similar to a top dog car, but I know it’ll be harder.

Name recognition goes a long way and down the road when the bubble on 90s German vehicles bursts, you’ll want the well known hardware on your hands.…
