*Edit 4/18/14*  If not sold by auction's end, this car will be sold locally!!



I am selling my highly modified 1986 Z-51 Corvette Coupe. This car just recently received over $20k worth in performance upgrades. There are 91K original miles on the body and frame and only 1K Miles on the entire drivetrain and suspension. It has an freshly rebuilt Automatic transmission. My original intent was to build a dual purpose roadracing/weekend street car but due to time restrictions and finacial difficulties I am forced to sell. I am the third owner of this vehicle and have owned it for the past 14 years. This car runs, brakes, and handles incredibly well! My main focus has been on the powertrain and suspension and was preparing to start on restoring the interior and body but did not have the opportunity to finish. Someone will have the chance to own an incredible C4 with an awesome array of high performance parts!

The car will need a little attention to the body and interior to make it perfect but as far as the drivetrain goes you are all set. The engine runs very strong and doesn't leak or smoke, perfect! This car is fast! To get a smoother cold idle and to squeeze more HP and MPG, I'd recommend a dyno tune, although the original chip has been modified by a mail order tuning company specifically for the combination used on this vehicle. The AC, emissions, and cruise control systems have been deleted for weight and HP purposes (Illinois does not require emissions tests for 25 yrs or older vehicles). The parking brake is also disconnected. The car sounds VERY aggressive on the street and is amazingly smooth on the expressway with hardly any interior resonance! Gets an average of 18mpg city/highway. I have got as much as 26mpg on the highway!

Before I get to the good stuff, I will start off by listing the areas that need a little attention:

- The most obvious is the front bumper. A car backed up on the front end as I was parked in a gas station, so the front bumper was replaced with a used one but not painted. Also, as a result, there were a few minor, barley visible, stress cracks in the paint on the front right corner of the hood as well. A few wires from the harness that runs alondside the bumper will have to be mounted correctly. I was planning to take it to a body shop and have them do it all at once but did not have the chance to do so. 

- All C4's have two sets of keys. One for the driver side door and one for the ignition. I accidentally misplaced the door key. A quick trip to a locksmith will take care of this. Ignition key/ with resistor chip and ignition blank keys are included though!

- There is a tiny impact crack on the windshield right beneath the widshield wipers, you cannot see the crack unless you lift the wipers up.

- The rest of the paint is in good shape and shines with some chips/scratches here and there consistent with age and use. The rear right fender is starting to have slightly visible spider webbing in the clear coat.

- The high speed setting on the wipers does not work, I believe the interior switch will have to be replaced. Intermittent and medium setting work just fine.

- The rear hatch glass hydraulic lift is becoming weak and will need to be replaced.

- Passenger selt belt sticks at times.

- Small leak around the door areas as common with older C4's, new weatherstripping will take care of this.

- Driver side power door lock switch mount in door panel needs repair as well as top trim (loose).

- A few little interior trim pieces are missing ie. the headlight knob and one of the rear targa top mount covers. All these can be easily purchased from an aftermarket corvette parts catalog like Eckler's or Corvette      Central. Interior squeaks and rattles common with 25+ year old C4's. Could be chased down and minimized.

- The radio head unit is made by Pioneer and has a CD player. The front 4 speakers are connected and work just fine. The rear speakers will require an additional amp to power up. I had one but it stopped working, All the wiring is done and ready to accept a new amp unit.

 Most of these repairs are minor and inexpensive. You will just need to invest a little time and effort if you want to make this car perfect.


Now onto the good:

Both window motors and ribbons were just replaced. The carpeting is only a few years old and all the "rear" interior trim pieces in the hatch are new as well as the halo trim. The entire engine was built with brand new parts down to the bolts with no expenses spared. All engine sensors are brand new. Only the best synthetic oils used. The suspension and braking system were completely restored with brand new parts as well. The automatic transmission was rebuilt with heavy duty clutches and the entire rear end assembly is brand new. Brand new wheels and tires. Basically nearly every single part under the hood and body are new and with less than 1k miles! There was well over $20,000 in high performance parts alone spent on this vehicle! This is not factoring in labor costs!

24 Hours of Le Mans live update part two

Sun, Jun 19 2016

We tasked surfing journalist Rory Parker to watch this year's live stream of the 2016 24 Hours of Le Mans. What follows is an experiment to experience the world's greatest endurance race from the perspective of a motorsports novice. Parker lives in Hawaii and can hold his breath longer than he can go without swearing. For Part One, click here. Or you can skip ahead to Part Three here. I write about surfing for a living. If you can call it a living. Basically means I spend my days fucking around and my wife pays for everything. Because she's got a real job that pays well. Brings home the bacon. Very progressive arrangement. Super twenty first century. I run a surf website, beachgrit.com, with two other guys. It's a strange gig. More or less uncensored. Kind of popular. Very good at alienating advertisers. My behavior has cost us a few bucks. I'm terrible at self-censorship. Know there's a line out there, no idea where it lies. I still don't understand any of the technical side. Might as well be astrophysics or something. For contests I do long rambling write ups. They rarely make much sense. Mainly just talk about my life, whatever random thoughts pop into my head. "Can you do something similar for Le Mans?" "Sure, but I know absolutely fuck-all about racing." "That's okay. Just write what you want." "Will do. But you're gonna need to edit my stuff. Probably censor it heavily." So here I am. I spent the last week trying to learn all I can about the sport of endurance racing. But there's only so much you can jam in your head. And I still don't understand any of the technical side. Might as well be astrophysics or something. While I rambled things were happening. Tracy Krohn spun into the gravel on the Forza chicane. #89 is out of the race after an accident I missed. Pegasus racing hit the wall on the Porsche curves. Bashed up front end, in the garage getting fixed. Toyota and Porsche are swapping back and forth in the front three. Ford back in the lead in GTE Pro. #91 Porsche took a stone through the radiator, down two laps. Not good. The wife and I are one of those weird childless couples that spend way too much time caring for the needs of their pet. French bulldog, Mr Eugene Victor Debs. Great little guy. Spent the last four years training him to be obedient and friendly. Nice thing about dogs, when you're sick of dealing with them you can just lock 'em in another room for a few hours. You don't need to worry about paying for college.

2016 Chevy Volt will have more EV range, bigger battery

Tue, Oct 28 2014

Meet the new Volt, not the same as the old Volt. That appears to be the story when General Motors introduces the 2016 Chevy Volt at the Detroit Auto Show in January. Today we're getting some more details on the guts of the new plug-in hybrid, and it turns out they're going to be much improved from the current Volt, which first went on sale at the end of 2010. Sure, the first-gen Volt did get some improvements along the way (a slightly larger battery pack, lane departure warnings) but the new Volt – which will go on sale in the second half of 2015 – marks the first time GM has been able to return to the drawing board and really make the improvements that its customers want. That's how Larry Nitz, GM's executive director of vehicle electrification explained it to AutoblogGreen today when explaining the all-new Voltec extended range electric vehicle (EREV) powertrain. "In the Gen 2 is we gave the engine a little more power, a little more torque, a little more displacement, more capability." – Larry Nitz Nitz said that the new Volt will be better in almost every sense: a bigger battery, longer EV-only range, 20 percent better acceleration in the low speed range and higher overall efficiency. This is due, in part, to the Volt's two motors being able to both act as generators and power the car. As we noted this morning, the 2016 Volt will use a larger, 1.5-liter four-cylinder engine, a version of which is already used in the Chinese-market Cruze. Nitz said that this has a number of benefits, including more power and quieter operation. "Some people would say, why did you make [the first-gen engine] so big. I would say, why did you make it so small?" he said. "It works good, our customers love it, but the reality is that if you go a little bit off and use the car a little harder, you can get the engine to need to operate at a higher speed. In an EV, that's quite noticeable. So, what we did in the Gen 2 is we gave the engine a little more power, a little more torque, a little more displacement, more capability and what it has marginally enabled is not only is it more efficient but it's also quieter." Nitz wouldn't talk about how the new powertrain might affect the two other products that use the Volt's underpinnings – the Cadillac ELR and the Opel Ampera – but if you've got a quieter option, we assume that's something ELR drivers would enjoy. But that's a story for another day.

Why 2015 is going to be a huge year for trucks

Thu, Jan 22 2015

Nissan chief executive Carlos Ghosn took center stage to introduce the 2016 Titan last week at the Detroit Auto Show. He spoke of the truck's new features, impressive Cummins V8 diesel engine and the extensive amount of time and money required to build a modern, competitive pickup truck. "We have done all of this because we see opportunity – an opportunity in the unmet needs of today's American truck customers," Ghosn said. He was speaking about the Titan, but his thoughts echo the industry's mindset: When it comes to trucks, find an opportunity and attack. Even with CAFE regulations looming and fickle consumer preferences, investing in trucks is a no-brainer for automakers. Some consumers will always need a truck for their job or lifestyle. And some people will always want one, whether they need it or not. With that in mind, here are four reasons why the pickup-truck sector is more important than ever and poised for growth in 2015. View 24 Photos The Nissan Titan Is Back Okay, it never left, but the Titan hadn't been redesigned since its launch in 2003, and Nissan sold more NV200s than Titans in 2014. It's an understatement to say the truck was languishing. That all changes with the 2016 model. The Titan will come in two variants, a traditional fullsize competitor and the Titan XD. The XD will lead the market launch, and it arrives late this year. It's pitched as a "whitespace" offering, Nissan sales and marketing vice president Fred Diaz said. The idea is to offer something in the general size and price range of a fullsize truck, but also have some of the capability of a heavy-duty truck. The XD uses a fully boxed ladder frame, the chassis design from Nissan's commercial division, and the wheelbase is about 20 inches longer than other Titan models. The XD, which Nissan is calling the flagship of the line, will be the only model with the 5.0-liter Cummins turbodiesel V8. It produces 310 horsepower and 555 pound-feet of torque, while being able to tow 12,000 pounds. V6 and V8 gasoline models will also be offered on the Titan XD and the standard, non-XD model. When production ramps up, the Titan will be sold with several cabs, beds and trims. New features include trailer sway control, an integrated trailer brake controller, more storage options in the cabin and even laminated front and rear side glass to reduce outside noise. All of this has given Nissan fresh confidence in an area where it admittedly has been lacking. "We can compete," Diaz told Autoblog.
