hello everyone want to introduce myself name is jon from ct i have a 2010 scion tc 1st gen love it bought brand new when i was 19 ...im almost finally done paying off i have pretty much all the exterior parts to make the car look the way i want...im really interested in performace at this point....i have 105 k on the motor but toyota has to pretty much replace the entire motor recall on these motor too much oil consumption...so besides the bolt ons i really want to boost my car which would probably be the last step for power gains...any opinions on good hp gains without having to open up the motor
