The Turbo 2.3 swap would be pretty simple on that car. You can use the factory EEC harness, just need to move some of the wires in the connector (like less than 10). The stock turbo motors put out 210 hp and I think 285 torque but can easily surpass that with minor tweaks. Many owners report over 30mpg on the highway and close to 30 combined city/highway. Is that car a 5 speed or auto?
