Modded budget Mazda Miata takes on new Porsche Boxster in more challenges

Earlier this month, our friends across the pond at Auto Express released the first in a two-video series that would see them try and build up a second-generation Mazda MX-5 Miata that could best a standard Porsche Boxster around the track. While that first video detailed the mods to the MX-5 - a supercharger, some suspension upgrades and a new set of super-sticky rubber being chief among them - and set baseline lap times for the stock car, today, we have the results of the 5,000-pound ($8,200) upgrade job.
Of course, we aren't going to spoil those for you. You'll need to watch the full video, which recaps the upgrades before digging into a comparison of both straight-line-speed differences between the 2.7-liter Porsche Boxster and blown Miata, as well as their behavior and lap times on the track.

eBay Find of the Day: 1981 Porsche 928 convertible by Carelli

The Porsche 928 was perhaps the consummate European GT of its day. With a powerful front-mounted V8 engine that grew in displacement as the model years went on, it was capable of eating up the miles at triple-digit speeds in great comfort for occupants. It was also an unusual beauty, with its sharp front and curved rear featuring innovative integrated bumpers.
Currently for auction on eBay Motors is one of the rarest 928s you're likely to find, in a handsome combination of Guards Red paint and tan leather interior, though we wouldn't mind a less-showy finish to the factory wheels. According to the seller, this car is one of eight 928 convertibles by Carelli Design, a firm that's still in business.
The auction claims that these cars were made in 1981 as a feasibility study between Carelli and Porsche for a possible production 928 convertible. The seller says he worked at the dealership where the car is said to have been originally sold $103,000. To remove the roof and hide the convertible top, there were significant changes made to the body and interior, including redesigned doors and a completely new trunk. As you can see in the gallery, when down, the top is completely hidden in a very factory-like fashion. When up, it looks slightly awkward, though (and we'd really like to see a rear three-quarter view to check out the blind spots).

Porsche 959 Prototype started it all

While Porsche was unveiling the new Nürburgring-dominating 918 Spyder downstairs in Hall 3 here at the Frankfurt Messe, there was another Porsche supercar quietly and discretely on display upstairs in the same hall. That, of course, was the 959. But not just any 959: this was the original Gruppe B prototype.
The 959 was first developed as a rally car in the early 80s to compete with the likes of the original Audi Sport Quattro S1, Ford RS200 and Lancia Delta S4. But Zuffenhausen soon saw its potential as a production road-going supercar, emerging as a technological marvel to challenge the decidedly linear approach of the Ferrari F40. It still stands as a groundbreaking supercar in its own right, but also lead to the first all-wheel-drive 911 Turbo and set the stage for the Carrera GT and aforementioned 918 Spyder that followed to cap the top of the evolving Porsche range.
This original Gruppe B prototype, which presaged the production 959, packed a 450-horsepower 2.8-liter twin-turbo flat-six into an even sleeker form than the final version that followed. We caught up with it on display as part of a display of 80s German classics, of which this 959 prototype immediately stood out as the pick of the proverbial litter.
