Re: XR8 inlet manifold
I would possible think you r wasting money on 1.7 RR, use 1.6's with a higher lift cam, and may save you a little money, although this would be info for an owner of an AUII XR8, so i don't know what type of RR's you have in the ED, but the rest sounds fairly run of the mill stuff. Possibly see if you can find a second hand GT40 upper and lower manifold and that will help heaps.
