ok everyone. here's the scoop. Im looking into single turbo systems for my auto. I was debating wether i wanted an Sp57 or a PHR street kit. I wanted to know the best bang for the buck, and my eyes led me to the street kit. For 3800 bux, it seems like a great deal. Paired with an aem ecu to top it off. The question is, if i wanted to stay on stock fuel and a stock tranny, is it possible to spray a small shot of nitrous ( about 50-75) and still maintain the turbos durability, since it's such a small turbo. I wanted to be in the 600 rwhp range w/ nitrous, and maybe if i get a 2800 rpm stall, it would be perfect for the track, and with nitrous it could be possible to hit 10's. How well do you think the phr street kit will hold together with nitrous? how bout the sp 57? any thoughts or HP figures that i could expect w/ race gas and nitrous? any help WOULD be much appreciated.
