Hello, after I had been on the market for a while for a 03 zy vert, I decided to call robert at hi-end auto, he had just what I was looking for. Very good people to deal with and I got a good deal. 49k miles, 2.8 upper, single blade tb, billetflow plenum, diablosport tuner and dyno tuned 453rwhp and 469tq (dyno sheet included). Recently took the car to the local 8th mile track and ran a 8.3 at 88mph with it on street tires. Looking to make around 500 rwhp in the near future!!!!!
