I have the last three years worth of SCC and Turbo magazines. Around a year ago SCC picked up a Probe GT and started disecting it. Through all the modifications that they did to the engine and the thousands of dollars that they spent on the vehicle there was no cheap horsepower to be found. They dinoed the vehicle after every modification was done and they found disappointment after each one. If you want power and serious power, you will be spending thousands of dollars on this car. Thats what the professionals found and that's why they dropped our car as a project just after a few installments. The biggest restrictor on our car is the VRIS. Starting with the MASS Air sensor. Installing a split second sensor in place of the air sensor we have in the car is a $1000.00 option. Is that worth it for 3-4 HP? Is a $600.00 Greddy Exhaust worth 1-2 HP? Every intake out there for our car produces 1HP between 5-7000RPMS. If you want HP I will tell you exactly how to get it. It will cost you around $5-10,000.00 if you want 3-400HP at the wheels. Talk to you all soon.
