An earlier deal on Bring a Trailer fell through for this 1988 Callaway Corvette Twin-Turbo, so now someone else has a chance to assume ownership of this historically significant car.
All Callaways are rare, but this particular Dark Blue Metallic example has something else going for it – after the original conversion, it was owned for the first three years by Corvette engineer, race car driver, and former director of GM Performance John Heinricy.
At that point, ownership transferred to the current seller, who’s kept it well-maintained at two different points in Oregon over the past two decades.
After the car originally sold back in August, the winning bidder failed to follow through on the purchase, said to be no fault of the car, but that person has been banned from Bring a Trailer and did not get their buyer’s fee refunded.
With five days left in the current auction, the high bid has already reached $50,000 – not far below the combined $67,136 MSRP of the car when new.
Whoever winds up being the new owner will receive Callaway documentation, NCRS paperwork and other documentation, service records, a letter from Mr. Heinricy, an accident-free Carfax, and a clean Oregon title in the seller’s name.
Extensive photos show the car to remain in excellent condition inside and out after 32 years, though close-up photos indicate a few paint chips on the front bumper and hood, among other locations.
Heinricy had the current gray leather power sport seats installed in place of the factory tan seats, and they are a fine complement to the blue exterior, in our estimation. The car is fully equipped, with niceties such as power windows and locks, automatic climate control, Delco Bose cassette sound system, and a Callaway boost gauge in place of one of the center dash vents.
Of course, the reason to buy a Callaway in the first place is the added power of the B2K twin-turbo package that considerably increases the performance of the 5.7-liter L98 V8 to 382 horsepower and 562 lb-ft of torque. Included in the conversion were proprietary .006”-oversized pistons lowering the compression rate to 7.5:1, a forged crankshaft, Clevite bearings, and stainless steel valves – along with the twin-turbochargers with integrated wastegates and dual intercoolers under hood ducts. It also has a modified Turbo 400 automatic transmission with a Laycock overdrive unit, a $6,500 option.
It is a little sad that the speedometer, as mandated by the federal government back in the day, peaks out at just 85 mph, but we’re sure it’ll go a lot faster – wink, wink.
Currently sitting with about 51,000 miles, the car appears to have been well maintained over the years, with the transmission and overdrive unit said to have both been serviced in 2011 and new U-joints installed in 2014. Callaway serviced it in 2009, and within the last month, the radiator has been rebuilt, new spark plugs installed, and fluids changed.
Watch the accompanying video, and you’ll see this classic C4 still looks like a lot of fun, despite being surpassed in the horsepower race years ago.
