1991 Chevrolet Corvette Callaway Twin Turbo
At the time, the Callaway Twin-Turbo Corvette was quite simply one
of the most powerful automobiles ever certified for sale by the
EPA. It's turbocharged and intercooled 5.7-liter V-8 put out a
staggering 382 horsepower-more power than any U.S.-spec model then
sold by Ferrari or Porsche. In fact, only one U.S.-market car at
the time could top the Callaway's formidable power rating: the
Lamborghini Countach, which belted out 425 hp. Even Chevrolet's
forthcoming Corvette ZR-1 was hard pressed to outpower the Callaway
For consignment, putting out a staggering 382hp with a twin turbo
mod, courtesy of Reeves Calloway, which turned out 2-3 versions of
this car each week. Our consignment with fiberglass bathed in Polo
Green, rear greenhouse glass and a black leather interior, has some
excellent small change in design features that even though first
present as subtle, all add up to high performance in the form of a
1991 Corvette Twin Turbo thrill ride.
This Callaway, in the eyes of some beholders, also offers a sleeker
look than the standard C4s, with its Sledgehammer-inspired Aerobody
and Z5G package that featured a deeper front air dam, 4 openings
for extra air in the front just below the hood hinges, and the
essential hidden headlights. Just behind the front wheel well is a
large vented opening foregoing the standard Corvette cove seen on
everyday models of this same year. Black trimmings for the glass
and handles, and the Mazda Miata-esque dual eyeball taillights, and
large oval exhaust outlets below the neoprene bumper. Also noted on
the rear quarter just aft of the rear wheel well, is another lean
horizontal ribbed opening vent presumably to help cool the brakes.
17-inch turbine style wheel coverings trim out wide all season
radials on all 4 corners.
Opening the black molded door coverings all neatly packaged in
panels and curved outcroppings for the power toggles and joysticks
we see some satin silver accenting in plastic, and even black
carpeting panels for the lowers. Inside like new leather racing
style buckets are in and these have nifty side bolsters to hold you
in while you are carving a curve. Also seen on the sides are the
seat 3 position memory buttons for the driver. A sleek center
console which houses the power seat adjusters and touring and
performance dial to change the suspension on the fly, are mounted
in just behind the shift lever. The dash on this version has become
more curved, and still houses the large warning light panel above
an aftermarket Clarion AM/FM/CD/Cassette Digital sound system.
Noted just below the radio is a Callaway gauge to measure boost
pressure. Also, a Callaway tag designating this as car as number 42
on the build ticker. In front of the driver is a cascade of pointer
analog gauges and in the center is an orange LED readout for fuel
level and speed, as well as digital mileage which is showing an
actual 36,112 miles. Nice clean black carpet floods the floors, and
the original steering wheel is present and accounted for. In back
behind the buckets and under the curved greenhouse glass is a black
carpeted multi level storage area.
The stout 8 banger in 350ci L98 form is under the hood. This sports
EFI and of course the Calloway signature Rotomaster twin turbos to
help it conger up more horses. A ZF 6-speed manual transmission is
on back along with a 3.07 axle. This engine has a forged crank with
premium rods and low compression 7.5:1 pistons from Mahle.
Stainless steel intake valves and valve springs are added in for
Our example makes heavy use of the aero panels underneath and these
are all in very good condition. Independent forged aluminum front
suspension parts are standard, and on back is an independent 5 link
with tow and camber adjustment and more forged aluminum control
arms and steering knuckle, along with transverse mono-leaf springs
with steel tie rods. Power disc brakes bring you back to earth on
your ticket into the superhighway system of the USA!
This Calloway is the most powerful Corvette I've had the pleasure
to drive, and I didn't even scratch the surface of its potential on
our test track. A quick starter, smooth runner and nice handling.
It can come to a panic stop on a dime. The seats are comfy and
sporty, and I noticed the service ride control light was
Another interesting low number out of factory modded Callaway
Engine Corvette for consignment. Looking and driving will have you
saying "Toto, we're not in Bowling Green anymore!"
