Base Corvette Sport Coupe (1YY07)

The base price of the 1990 Chevrolet Corvette Coupe is without any optional equipment.
A 350 cubic inch, 245/250 horsepower engine, 4-speed automatic transmission, removable body-color roof panel, and cloth seats were included in the base price.
Seat designs were the same for 1990 as they had been for previous years with the exception that backs would latch in the forward position. Sports seats were available with all models and suspensions in 1990.
An air intake speed density control system, camshaft revision, and compression ratio increase added 5 horsepower to base-engines, increasing base horsepower from 240hp to 245hp (except coupes equipped with 3.07:1 or 3.33:1 axle ratios which increased horsepower from 245hp to 250hp because of their less restrictive exhaust systems.
The 1990 model instrument display panel was redesigned as a “hybrid” combining a digital speedometer (similar to that found on earlier model C4’s) and conventional analog gauges for the rest of the display – including the tachometer, oil pressure, battery voltage and fuel levels.
An engine oil life monitor calculated useful oil life based on engine temperature and revolutions. An instrument panel display alerted the driver when an oil change was recommended.
A supplemental inflatable restraint system (SIR) with an airbag was added to the driver’s side of the dashboard and a glove box was added to the passenger side (a feature previously absent on all earlier model C4’s).
The “ABS Active” light was removed from the driver information center.

Callaway Twin Turbo (not GM installed) (B2K)

Addition of Callaway Twin Turbos to the existing L98 engine.
This option generated a specific equipment build with standard engines at the Corvette assembly plant. The cars were then drop-shipped to Callaway’s Connecticut shop for installation of Callaway-modified twin-turbo engines.
This is not a factory installed option. The Callaway Corvette could be ordered through participating Chevrolet dealers. Fully assembled Corvettes were then shipped from the Bowling Green Corvette plant to
Callaway Engineering in Old Lyme, Connecticut, where it received engine (and other) modifications.
The 1990 Callaway Corvette had performance ratings of 390 horsepower and 562 lb.-ft torque.
Automatic transmissions (reworked truck Turbo Hydramatic 400s) were available for $6500.00
Full Chevrolet warranty applied except for powertrain which was covered by Callaway for twelve months or 12,000 miles.

An optional, removable hardtop.
This option was new for the 1990 Corvette Convertible.

Performance Axle Ratio (G92)

Optional performance axle ratio of 3.07:1 or 3.33:1.
Was only offered when the Corvette was ordered with an automatic transmission.
The actual “Performance Axle Ratio” varied from year to year. The G92 Option was available when ordering either the Corvette or the Camaro throughout the 1980’s and early ’90’s.

Engine Block Heater (K05)

An electric heater that heats the engine of a car to ease starting in cold weather.
This option was not available with the ZR1 option.

Engine Oil Cooler (KC4)

Internal cooler used to cool internal components of the automobile’s internal combustion engine.

6-Speed Manual Transmission (MN6)

An optional, no-cost, 6-speed manual transmission.
The six-speed manual transmission was designed jointly by ZF (Zahnradfabrik Friedrichshafen) and Chevrolet and was initially built by ZF in Germany.
A computer-aided gear selection feature bypassed second and third gears (and locked out fifth and sixth) for improved fuel economy when a series of low performance criteria were met.

California Emission Requirements (NN5)

Revised emission/exhaust components to meet California Emission standards

Low Tire Pressure Warning Indicator (UJ6)

Low tire/air pressure monitoring and warning system.
Sensors strapped to each side of the inside of each wheel sent a radio signal to a instrument-panel receiver if pressure in any tire dropped below a preset limit.
This option was included as part of the ZR1 package.

Luggage Rack (convertible) (V56)

Optional luggage rack that was mounted to the rear decklid of the Corvette convertible.

Performance Handling Package (coupe) (Z51)

Heavy Duty Steering and Suspension Upgrade for improved handling.
The Z51 option included RPO KC4 Engine Oil Cooler, heavy duty suspension and brakes.
Was only available in coupes equipped with a manual transmission.

Special Performance Package (coupe) (ZR1)

Extensive performance upgrades to the base model Corvette.
The ZR1 option included unique bodywork (doors, rear quarters, rocker panels, rear fascia, and rear upper panel.
ZR1 optioned Corvettes were fitted with special Goodyear Z-rated P315/35ZR17 tires that were mated to 11-inch wide rear rims.
The ZR1 option included a number of other RPO’s (normally listed separately) including: Power Passenger Seats (AC1), Power Driver Seats (AC3), Sports Seats, Leather (AQ9), Selective Ride and Handling, electronic ( FX3), Stereo System with CD, Delco Bose (U1F), and Low Tire Pressure Warning Indicators (UJ6). Additionally, the six-speed manual transmission (MN6) was required.
The ZR1 was also fitted with a special LT5 engine (that was unique and limited to the ZR1 coupe.) The LT5 engine was designed with the same V-8 configuration and 4.4 inch bore spacing as the standard L98 engine, but was otherwise an all new Chevrolet/Lotus design with four overhead camshafts and 32 valves..
Despite extensive use of aluminum, the complexity of the LT5 engine caused it to weigh just under 40 pounds more than the base model iron-block engine.
The LT5 Engine produced 375 horsepower but still managed to avoid the EPA’s gas guzzler tax.
The LT5 Engines were assembled by Mercury Marine in Stillwater, Oklahoma, and were then shipped to the Corvette plant in Bowling Green Kentucky for ZR1 Corvette assembly.
Chevrolet service departments returned LT5 engines to Mercury Marine for certain repairs. Customers were given the choice of a replacement engine or return of their original engine, if repairable.
RPO K05 (Engine Block Heater) was not available when the ZR1 option was ordered.
The ZR1 option was only available in the coupe bodystyle.

Notes

For a limited time, Chevrolet dealers could order Corvettes destined for the World Race Series.
Merchandising code R9G triggered deviations from normal build, such as heavy duty springs with FX3.
Owners could buy sealed race engines from Chevrolet, although modifications to the engine were the car owner’s responsibility. Twenty-three 1990 R9G Corvettes were built.
1990 Corvettes had improved ABS (Anti-Lock Braking System) and improved yaw control.
The RPO V01 Radiator and B4P Boost Fan were not optional in 1990 as both were unnecessary due to 1990’s more efficient, sloped radiator design.
Corvette did not pace the 1990 Indianapolis 500, but 80 turquoise or yellow “Indy Festival” convertibles with special graphics were built for the event
