I just thought with all the debate and talk about AMS, Buschur, RNR, ATP, HKS turbo kits floating around (sorry other vendors if I forgot any) that maybe another option to look @ is the turbo kits from ultimate racing. I went with them and I've gotten good customer service so far and my kit is almost here....can't wait to try it out. They got great results just tuning with an emanage on an evo on Incognito's car and Darryl just informed me that a wrx with the same turbo kit on stock motor ran a 11.2 @ 128mph using the utec. To me...that seems like proven results also. Just thought I'd give some people heads up about their kit for those considering an upgraded turbo.
