PowerPages: 1991 Toyota MR2 Turbo
Conclusion
With two performance items and a tune-up, we netted a total of 26.5 hp and 22.6 lb-ft of torque. Pretty impressive numbers for a 15-year-old car. The turbo seems to be holding up well considering its age, which is in part a testament to its owner. With heavy use and neglect, the turbo can go bad and require a rebuild or replacement. This car still has room to grow. With a larger intercooler, boost control and fuel programming, solid 200 plus-hp figures aren't too far away.
