eBay Find of the Day: 1981 DeLorean with 570-hp twin-turbo Buick V6 [w/videos]

"Are you telling me that you built a time machine... out of a DeLorean?" So asked one Marty McFly of his mentor Dr. Emmett Brown, who replied: "The way I see it, if you're gonna build a time machine into a car, why not do it with some style?"
Doc Brown was right, of course: with an exotic mid-engine layout, gullwing doors and stainless steel body, the DeLorean DMC-12 sure looked the part. It just needed a little more juice. Well this one might not have 1.21 gigawatts of time-bending power - that'd be more than one and a half million horsepower - but it does have more than the 150 hp in the the standard 2.8-liter V6.
That's because this particular DeLorean has had its stock Peugeot Renault Volvo engine swapped out for a Buick-sourced, all-aluminum, 4.3-liter V6 from the Grand National. Dutteiller Performance didn't leave the engine in stock form, either: while they were swapping it out, they added a pair of turbochargers, new pistons, crank, cams and much, much more.

GM warning 800,000 owners that their cars may need oil changes more frequently than they say

The days of changing your engine oil every 3,000 miles are long gone thanks to most cars having automatic oil monitoring systems, but about 800,000 General Motors vehicles apparently have incorrect monitoring software that is leading to premature engine component wear. According to Autoweek, certain 2010-2012 Buick LaCrosse, Regal, Chevrolet Equinox and GMC Terrain models equipped with 2.4-liter four-cylinder engines could be going too long in between oil changes resulting in a higher-than-normal number of warranty claims for the engine's balance chain. The balance chain links the balance shaft to the crankshaft, and a worn one can produce higher noise levels.
As a fix, GM dealers will be reprogramming the software for the monitors in an effort to reduce the interval between oil changes, which varies based on driving habits and conditions. Through February 2015, the software update will be done at no cost to vehicle owners, but since this is not a recall, after that point, it will be up to the discretion of dealers as to whether or not they will charge for the service. What isn't immediately clear is whether GM plans on giving assistance to out-of-warranty customers who are experiencing engine issues from the worn chain.

1969 Chevrolet Chevelle vs 1987 Buick GNX in Generation Gap showdown

Generation Gap generally tries to adhere to a theme for each episode, and for the final video from the Lingenfelter collection, the series might have its best idea yet - limited-production muscle cars from General Motors.
On one side you get a 1969 Chevrolet Chevelle COPO, and it's an absolute sleeper. Other than the SS wheels, this classic coupe looks practically bone stock, at least until the engine fires up. Under the hood is a 427-cubic-inch (7.0-liter) V8 making a claimed 425 horsepower and 460 pound-feet of torque. This was the sole year for the COPO package on the Chevelle, and Chevy only made about 323 of them.
The Chevelle's challenger is almost as rare and arguably just as cool. The 1987 Buick Grand National GNX looks just as mean today as when new. It eschews a traditional muscular V8 in favor of a 3.8-liter turbo V6 making a claimed 276 hp and 360 lb-ft, although that number is supposedly a bit underrated. Also, just 547 examples of the GNX version were ever built making it quite a collector's item too.
