Been there and done that in a 350z.... It wasnt an STS kit but we built our own kit for my friends 05 Z. Its still running strong as hell... The only problems he ran into was boost leaks. Once we were able to find them all and make sure everything was tight he never had any problems. He was putting down something in the neighborhood of 390whp and has been for about a year and a half.
People talk about the lag because its so far away from the engine bay but I didnt really notice much more lag than would be on any other single turbo setup. I think he hits full boost right around 32-3500... The car feels sick as hell.... I put down 426 on my Vortech and he beat me in the 8th mile, I was running between 8.3 and 8.5 consistantly... he was in the high 7's..... made me sad so I sold it all lol hopefully soon ill be grabbing up a 370 Roadster
