i am looking for a bit of advise on a 04 ba xr8 ute i bought last week i want to know if i need to upgrade the oil pump and replace the timing chain as i have been told that thay are not the best. has anyone done this and does anyone know the cost involved or the best replacement product. i am also looking for the best cat back exhaust choice for best power gain.
i am also looking at a chip but want to know if this is a good idea. i have heard they put more stress on your motor.
