The Story:

I owned my first Corvette at age 18 when I was still in high school. It was a black Z52 C4 coupe which is now the Stalker Corvette that I document on this site. Driving it made me an instant fan of Corvettes. During the C4 production (1984-1996), the B2K Callaway was one of, if not, the most sought after models for its performance, styling and low production numbers. These cars generally sell for $20k-$70k depending on year, options, mileage and condition. I would regularly search for the term “Callaway” on ebay just to see what the market looked like and what was for sale. I had no desire to own a basket case or high mile car so the lower priced cars weren’t going to work.

In early April of 2011, I was doing my normal ebay car searches and nothing unusual came up when trying the term “Callaway” but I did find an auction for a “Supercharged Corvette” that peaked my interest. Sure enough, it was a black genuine Callaway wearing an Aerobody kit that had been advertised incorrectly. The seller was Manhattan Motor Cars, a high end exotic car dealer located in New York City.

I thought about contacting them overnight and finally did the next morning when the auction still had zero bids on it. I explained to the salesman that I was interested in the car and we negotiated a price pending my inspection. I called Callaway Cars Inc. and was told that it was an authentic B2k car that had not been back to their facility since it was originally built. That afternoon, I put down a deposit on the car and signed a contract without having ever seen it.

The car is number 43 of 58 B2K Callaway cars built in 1990 which was the lowest production year. At the time that I received the car, it had only 3,265 miles on the odometer and was a one owner car. It was originally sold at Valley Chevrolet in Wilkes-Barre, Pa and carries a build date of 3/90 and a delivery date of 8/90. It was first registered in 1990 with 240 miles on the odometer. The next time it appeared in public was in 2008/9 where is was on consignment at Corvette Mike’s in New England. Then it did some time at Billy Bob’s Fast Expensive Cars in Lakewood, NJ in August of 2010 with an asking price of $49,500.


During the Callaway conversion, it received everything included in the RPO-B2K option as well as the Aerobody kit, Dymag wheels, and the extremely expensive and rare option called the Kooloff windshield. A representative of Callaway Cars Inc. told me that the car had been ordered without the windshield option, but was installed by mistake so the dealer ended up getting a replacement piece for Callaway to replace the one that was installed in 043.

About Callaway Cars:


From the Callaway Owners Group website-

“It was the Alfa Twin Turbo car that was the catalyst that sparked interest within the ranks of General Motors (GM) towards Callaway Cars and their engineering abilities. In the early 80’s GM was looking at high performance engine options such as turbo charging and multi-valve technologies. GM was aware of Callaway’s reputation and the cars it had produced. In fact, they had taken a Callaway Alfa Twin Turbo and examined the work closely. After GM’s own twin turbo V6 and V8 projects had run their course, Dave McLellan gave the nod to Callaway, authorizing him to develop a prototype. The resulting prototype was introduced in June 1986 to GM and the media. With 345 hp and 465 lb-ft torque, the twin turbo V8 package was engineered to be the ultimate Corvette package, producing tremendous power while retaining its emissions controls and a complete warranty.


The Callaway Twin Turbo Corvette became known as Chevrolet option RPO B2K and was available through select Chevrolet dealers both in the United States and abroad. It continues to hold the distinction of being the only engine package produced outside of GM to hold an RPO code, something that will probably never happen again. Produced between 1987 and 1991, over 500 of these special Corvettes were made in coupe, convertible, and at the close of production, the Speedster form. By ordering a Corvette through the dealer, and checking the option box for B2K, it triggered a series of events, which ensured the cars received special equipment and handling under SEO Z5G.


Throughout production, changes were made. Optional wheels were available in 1987 cast out of magnesium from Dymag in England and were available in 16-inch diameter and later in the year, a 17-inch size. In 1988, power levels increased. Horsepower was now rated at 382 and torque rose to 565 lb-ft. That year also saw the 17-inch Dymag wheels become standard equipment with other options such as an automatic transmission and full leather interior also was offered. Available for the 1989 B2K was the handsome Aerobody designed by Paul Deutschman and first seen on the Callaway Sledgehammer Corvette. It became available mid year on the production versions and replaced or installed over the lower panels of the car. 1990 brought more power once again. Horsepower rose to 390 and torque output was 562 lb-ft. however; the automatic transmission was no longer available. 1991 was the final year for the B2K option with power up again, this time to 403hp and 575 lb-ft. A subtle change to the hood included the installation of blisters to duct cold air to the intercoolers. The Aerobody, introduced in 1989 continued to be an option and late in the year, the Speedster model was revealed.”
