Production Numbers Welcome! The Callaway Owners Group is dedicated to the preservation of the world's most powerful Corvette. Callaway Twin Turbo Corvette Production Numbers The Callaway Twin Turbo Corvette was officially produced, between 1987 and 1991 under the Chevrolet Regular Production Option “B2K”. 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. While the final production exceeded 500 Corvettes, the total that were ordered through the Bowling Green plant was lower due to a few factors. These factors included many dealers sent cars already in the process of delivery to their stores, or may have been on their lot and were used to "prime the system," as Reeves Callaway has explained to us. "Callaway Cars was under obligation to deliver a product, and we did so by taking some cars in after they left the Bowling Green Assembly Plant." These cars would not have had the RPO code in the glovebox, but would have been built using the exact same parts list and built to the same standard as any other Callaway Twin Turbo Corvette. Individuals could also send in their own Corvettes to Callaway in Old Lyme for what is called a “Direct Conversion”. These cars are built to the same standard as the cars during the Twin Turbo program however, some parts might be changed for what was currently available. As an example, a flat-hood on a 1987, or different wheels, etc. The production numbers listed below are broken down as best as I could and while the final count is very close, there are still a few mysteries to be solved. 1986: One 1986 Callaway Corvette was constructed. This rare Callaway was built, using an equally rare Malcolm Konner Special Edition Corvette (RPO 4001ZA) coupe as its foundation. Originally wearing BBS mesh wheels, Silver 16 inch Dymag wheels were added at some point in its history. 1987: 167 cars were ordered with RPO B2K, while Callaway records show 188 cars constructed. You may have also seen the number of cars built listed as 184 (121 Coupes & 63 convertibles) however, four more cars were produced bringing the overall total to 188 Callaway Twin Turbo's for 1987 (123 coupes and 65 convertibles. 1987 ‘s wore the factory wheels for the most part, with two different Dymag Magnesium wheels offered during the model year. Optional 16" Dymags available, wore a dark graphite finish. According to records, fewer than two-dozen sets of the 16" Dymag cast magnesium wheels were fitted to Callaway Corvettes for the 1987 model year. Most cars produced, wore their regular Corvette wheels appropriate to their suspension (RPO) code. The 16" Dymags were charcoal in color, although a few have subsequently been painted other colors by their owners after delivery. The Dymag wheels were an expensive option, costing owners an additional $2,995 over the cost of the Callaway engine option. Offered later as an optional upgrade, the next generation of Callaway Dymags could have been fitted. 17” in diameter, these wheels wore a silver finish. These were the Dymags that became standard in 1988 on the Callaway Corvette. Though not an official option, two of the 1987’s
were equipped with automatic transmissions from Old Lyme, CT. 105 cars were ordered with RPO B2K, while Callaway records show 125 cars constructed. Bowling Green records showed 50 coupes and 55 convertibles made while Callaway records showed 60 coupes and 65 convertibles. 1988 also saw the official release of the automatic transmission – 10 coupes and 16 convertibles were equipped this way. In 1988, Corvettes saw 17-inch wheels become available. Callaway Corvettes for that year (and subsequent years) wore handsome, silver 17" Dymags that utilized the base Corvette locking center cap. 1989: This year saw the fewest Callaway Corvettes ordered through Bowling Green with RPO B2K. Only 51 cars were listed as ordered this way, 32 coupes and 19 convertibles. Callaway records show 67 cars constructed, 43 coupes and 24 convertibles. It should be noted however, that one more car was constructed after the tally was taken, skipping one car in the production sequence. I have personally driven #89-069, which is an Aerobody 6 speed convertible, and it is understood that this car was the final unit made for the 1989 run. The automatic transmission was offered again in 1989 with 8 coupes and 9 convertibles equipped that way. 1989 also saw the release of the Callaway Aerobody. Available on coupes and convertibles, this extremely attractive bodywork could be ordered along with your new 1989 or, retrofitted to any previous Callaway Corvette. 1990: 59 cars were ordered with RPO B2K this year, while Callaway records showed 58 cars constructed. Bowling Green records reported 38 coupes and 21 convertibles made while Callaway records state 37 coupes and 21 convertibles were constructed. Gone for this year, was the automatic transmission however, the B2K option was now officially available for sale in California. The Aerobody also continued to be an option on these cars. 1991: Bowling green records showed that 25 coupes and 38 convertibles were produced while Callaway’s numbers (which included Speedsters into the tally) stand at 71. The cars constructed were, 27 coupes and 44 convertibles. Again, these numbers take into consideration, the Speedsters constructed during this year and that model is broken down a bit further below. In addition to the Speedster option from Callaway, the Aerobody was also optional this model year as well. Speedsters: Series I Speedster Production was 10 cars. These
cars were powered by the L98 Twin Turbo powerplant and were custom
tailored to the owner’s style and taste. End of an era: At the end of the 1991 model year, the official B2K production came to an end. The final count from Bowling Green stands at 445 cars while Callaway’s numbers reflect 510 cars constructed. It should also be mentioned, there was one 1986 Callaway Corvette built. Constructed from a unique Malcom Konner Special Edition Corvette coupe, it is one of a kind and wears a set of silver 16” Dymag Wheels. The final chapter on that generation of Callaway Twin Turbo Corvettes came in 1994 with the third and final LT5 based Twin Turbo being constructed. This 94 ZR1 was finished in Aqua metallic with gray leather interior and wears a standard body with two large ovals opened in the hood section to allow airflow through the huge front mounted intercoolers. This car is fitted with 18” RW magnesium wheels. Speedster | 1986-2001 | C12 Production Production Production Please consider these numbers a guide.
