What are your mods? We need more information, if the car is stock it isnt going to benefit from a cam change really. I swaped a comp 270 in mine for a little more grunt. The E-303 is a proven cam but there are far better cam designs out there. Once again depending on the useage of the car and the mods will help you pick the cam. Instead of the E-303 I would go with the TFS-1 it is a pretty good street cam and is fairly cheap, the comp cam I got was 250+ shipping, it is a nice cam and pulls hard after 1500 with no loss of torque, but i think the TFS-1 could do the same.
