the funny thing is that this is the thing i have been telling through the cluster of all the posts to go with a turbo setup. Also EVERY at that range of power is custom, companies do not make kits out of the box that will make 2k hp. Your probably looking at 12-15 k for a dialed in twin turbo set up with all the bells in whistles, custom down tube, manifolds (because you cant use headers) and ect. They are extensive builds but worth the money easily. First you need to see what your block can effeciently spool, it is not about just getting the biggest turbo possible its what is going to work optimum for your car and give you no turbo lag. The shop should be able to tell you in a heart beat what to get. Or again go on LS1tech, i have no clue why you have no subscribed to that forum every one in the camaro world is on that site.
as for the racing you have not raced before if you say its not on a track driving around town punching it or going around the hills is not racing. You hicup with an 8 second car your dead. Honestly i wouldnt drive one period, i dont think I am that good of a driver to handle that much power, I have drove 1000rwhp and that scared the shit out of me. Now i know there are lambos bugatis that have 1000awhp or rwhp but a race cars 1000hp is different with the weight and gearing. When your front end launches and all you can see is the sun your ass hole gets TIGHT.
