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:

CLICK FOR DETAILS: 2006 BMW M5 Dinan 5.8 on eBay

Year: 2006
Model: M5 Dinan 5.8
Engine: 5.8 liter V10
Transmission: 7-speed sequential-automatic
Mileage: 72,000 mi
Price: $40,000

Dinan! One of 42 in the world! This truly special vehicle is no ordinary M5 with a measly 500hp. This M5 is one of 42 in the world with a 5.8L Dinan Stroker motor and required Carbon cold air intake producing approximately 600hp and 458 ft.lbs. This machine pulls furiously straight up to the 8,400 rpm redline. To build this vehicle on your own would cost you $70,000. She will hit sixty in approximately 3.7 seconds and has a top speed of over 200 mph. Dinan is the only aftermarket manufacturer sold, installed and maintained by BMW Dealership and matches BMW Warranties. The engine was swapped in around at around 47,000 Miles so the engine is still young. Otherwise, this machine is a prime example of a M Legend! There are newish Michelin Pilot Super Sport Tires installed at 60,000 miles. She is a great machine and I hate to sell her but with a second kid on the way it is time. Please let me know if you have any questions or would like certain pictures.

Factory options – Many standard features as the M5 was already the highest trim level. The extra cost features included:

It’s pretty amazing that only a claimed 42 of these Dinan 5.8s were made and I wonder if that number includes M6s by just referring to the motor or if there are just 42 M5 5.8s. As noted by the seller, the cost of the build from Dinan was as staggering as the amount of power produced. A decade on, the numbers don’t seem quite as outlandish but are still capable of matching class leading performance – perhaps a testament to how amazing this motor was and still is. That said, is it a $40,000 example? When you can get a nice E60 M5 for half that amount with less miles, it’s hard to consider it a deal. But in the performance realm, it’s still a pretty serious top trump as long as it doesn’t implode on you as the mileage increases.

    I know the styling is not for everyone and I’ve heard the shift quality of the sequential auto is not the smoothest during less aggressive driving. Can any of you M5 experts tell me if the car overall is solid (E60s in general – not necessarily Dinan)? Any major concerns to be aware of? These seem like a lot of bang for the buck.

    there is/was another Stroker E60 for sale in AZ, IB/Silverstone interior 50k ask 58k miles
    so when compared this one is high..
    @pm…the early cars had some issues (Red Cog)…software for the SMG…but engine/suspension wise they were fine…the styling was what polarizing..especially seeing that this followed the E39.
    But that V10 is just glorious esp. at wide open throttle…
    the only real concerns should be that the maintenance has been kept up/documented…

    Six hundred ponies? Egads, that’s a monster. I must look up the sound of acceleration on YouTube.
