The 1991 Toyota MR2’s transformation from econosport to legitimate mid-engine performer wasn’t just about aesthetics. While its sleek profile and 200-horsepower turbo option grabbed attention, the real story lies beneath the surface. Performance exhaust systems promise to reveal hidden potential, but they’re only part of the equation. The mid-engine layout that makes this car special also creates unexpected challenges that owners don’t discover until it’s too late.
Introduction
The second-generation Toyota MR2 arrived in 1991 as a radical departure from its predecessor, transforming from a wedge-shaped econosport into a curvaceous mid-engine sports car that could rival European exotics. Toyota’s engineers completely reimagined the platform, creating a larger, more powerful machine that’d compete directly with Porsche’s entry-level offerings. The SW20 chassis brought sophisticated suspension technology, including MacPherson struts up front and dual-link setups at the rear, delivering exceptional handling dynamics.
The 1991 model introduced two distinct variants: a naturally aspirated version producing 130 horsepower and a turbocharged model generating 200 horsepower. Both engines featured Toyota’s proven 2.0-liter 3S powerplant, renowned for its reliability and tunability. The car’s sleek bodywork, penned by Toyota’s California design studio, showcased flowing lines that wouldn’t look outdated decades later.
Performance Exhaust Systems Available
Anyone looking to enhance their MR2’s exhaust note and performance has numerous aftermarket options that’ll transform the driving experience. HKS offers their popular Hi-Power system, which reduces backpressure while maintaining street-friendly volume levels. Tanabe’s Medallion Touring delivers a deep tone without drone during highway cruising. For track enthusiasts, Greddy’s Power Extreme II provides maximum flow with its straight-through design and titanium construction.
Budget-conscious owners can’t go wrong with DC Sports’ stainless steel cat-back system. It’s delivered impressive dyno gains of 8-10 horsepower on naturally aspirated models. Those seeking aggressive sound should consider Apexi’s N1 Evolution, though it’s significantly louder than stock. Most systems bolt directly to factory mounting points, making installation straightforward for DIY mechanics with basic tools.
Mid-Engine Layout Trade-offs
While mid-engine placement delivers exceptional handling balance, owners must accept several practical compromises that affect daily usability. The MR2’s engine sits behind the cabin, eliminating rear seats and creating minimal storage space. The front trunk holds only 2.5 cubic feet, while the rear compartment can’t accommodate luggage due to engine heat. This configuration also restricts rearward visibility, making parking maneuvers challenging without practice.
Maintenance costs increase since technicians need more time accessing components. Simple tasks like checking fluids require removing panels. The engine’s proximity to the cabin generates more noise and heat, especially during summer months. Weight distribution that’s ideal for cornering makes the MR2 trickier in wet conditions—throttle control becomes critical to prevent snap oversteer that’s caught many drivers off-guard.
Frequently Asked Questions
What Are the Common Transmission Problems in the 1991 MR2?
The 1991 MR2’s common transmission problems include worn synchros causing difficult shifting, clutch hydraulic system failures, and gear grinding. Owners often report fifth gear pop-out issues and leaking transmission seals that require prompt attention.
