hey, all I can tell you is that xs power stuff gets mixed reviews, and from personal experience I wish you luck with it, I had a xs power manifold that I had to weld every month, but my girl bought me a new xs power manifold, no different then the one I had and it runs fine, so it's kinda like the lotterry on that, also I just did my gsr turbo and I would defenitely recomend getting your computer chipped, I have done my homework on this and I would recomend getting with John Vega, he is a very helpful guy who will tell you what you need (he did for me and my ECU is on it's way to his shop to get chipped) go the Uberdata, hondata or chrome route, I tried for 2 months to get my car running with an apexi super afc and it never ran right, Jonh has a great reputation on the boards and Im sure he would help you as much as he has helped me out, his website is http://phearable.net/. give him a try and good luck to ya.
