1986 C4 Corvette Auto Highly Modified Superram Borla 350 V8 Zz4 3.73 Roadracing on 2040-cars

*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!
