1988 Chevrolet Camaro IROC-Z Convertible — 5.7L TPI V8 with Performance Upgrades Why This Car Is Special The 1988 Chevrolet Camaro IROC-Z Convertible is one of the more difficult configurations to find in the third-generation Camaro market. Chevrolet did not build the IROC-Z convertible in-house. Instead, the conversion was performed by American Sunroof Corporation, better known as ASC, Inc., which had a contract with General Motors to handle open-top versions of the third-gen Camaro. ASC removed the factory roof structure, reinforced the body to compensate for the lost rigidity, and installed a folding soft top. The result was a factory-sanctioned convertible that carried a full GM warranty. These cars were more expensive than the coupe when new, sold in lower numbers, and have always commanded stronger collector interest. The IROC-Z name itself traces back to the International Race of Champions, a one-make racing series that used identically prepared Camaros to judge driver skill rather than equipment. Chevrolet licensed the IROC name in 1985 and applied it to the top trim level of the third-generation Camaro, sitting above the base model and the Z28. By 1988, the IROC-Z was the performance flagship of the Camaro lineup, available with either a 5.0-liter TPI V8 or, as optioned here, the 5.7-liter TPI V8 — the same displacement engine used in the Corvette of that era. The 5.7 was coded RPO B2L and was a genuine option, not a dealer add-on, making it the engine that serious IROC-Z buyers selected when they wanted the most the car could offer from the factory. This particular car sits in blue over a gray cloth interior, carries the 5.7-liter Tuned Port Injection V8, and has been fitted with a focused set of bolt-on performance upgrades that add capability without altering the fundamental character of the car. It is a driver-quality IROC-Z convertible with real-world improvements already done. Features List - 5.7L TPI V8 Engine (RPO B2L) - 700R4 4-Speed Automatic Transmission - MSD Ignition Upgrade - Edelbrock Performance Parts - BBK Performance Upgrade - Dual Exhaust System - Chrome 5-Spoke Wheels - Red Brake Calipers - Air Conditioning - JVC Bluetooth Stereo (KD-T720BT) - Bucket Seats - Center Console - Tachometer - Power Windows - IROC-Z Convertible Body - Strut Tower Brace Mechanical The engine in this 1988 Chevrolet Camaro IROC-Z Convertible is the 5.7-liter Tuned Port Injection V8. The TPI system, which Chevrolet used across the third-gen Camaro and C4 Corvette from 1985 onward, was a significant departure from the carburetor setups it replaced. The long-runner intake manifold with individual throttle body injectors per cylinder was designed to maximize low- and mid-range torque, which is exactly where a street car spends most of its time. In stock 1988 form, the 5.7 TPI was rated at 230 horsepower. The upgrades on this car build on that baseline in a sensible and well-regarded way. MSD ignition components are visible in the engine bay and are among the most common and well-regarded upgrades for TPI engines. MSD's multiple-spark discharge technology ensures a more complete burn at lower RPMs and during cold starts, which also reduces the chance of fouled plugs. Edelbrock and BBK both make bolt-on components specifically suited to the TPI platform — intake improvements, throttle bodies, and cold-air induction components among them — and the presence of both brands' stickers in the engine bay indicates this car has received attention in the right areas. These are not dramatic modifications. They are the kind of parts that enthusiasts have been bolting onto 5.7 TPI engines for decades with consistent, predictable results. The transmission is the 700R4 4-speed automatic, which was the standard automatic pairing for the IROC-Z in 1988. It is a well-proven unit with an overdrive fourth gear that keeps highway RPMs reasonable. The strut tower brace visible in the engine bay adds chassis rigidity by tying the front strut t
