what should I expect from the greddy.....

Hi all you Honda turbo guys! I am going to purchase a 92-93 civic HB with the 1.6L VT motor. Now I want to get the greddy turbo kit for it. How much HP should I expect to gain. The website dosent really tell much. This will be a car for me to have fun with while I save up for the New GST. Around here you can get civic's for about 2500-3500, so I was going to get one and then save up for my next project, but I still want to have fun in the tuner scene. What do you think? Greddy kit worth the 1500 bucks? How much HP will it put to the ground????
