Nice, wanted to go with the ute xr8/xr6t rear but got the AU XR8 hemisphere for free so giving it a go. Exhaust has ended up being a custom job, 3 inch to the rear after the gutted cat from the turbo, funny thing they told me was the xr8 was too small exhaust for the turbo, looks like a good sales pitch on me, hook line and sinker, lol. Main concern was drone, this is the baby mobile, so it has to act and sound nice for the wife lol. Did you switch pumps in fuel system, still have the xr6t pump but was thinking of swapping it for the upgraded walbro pump from herrords, the one with the bigger swirl pot. My phoon is going in for 1000cc injectors, billet wheel, and .70 comp housing (running on e85), so was going to put the my old nizpro drilled injectors from the phoon into the wagon and probably get the rapid v3.0 for the wagon. Mainly aiming to get 280-300rwkw all day everyday in all conditions. What tailshaft are you using, is it the xr8 gear with diff? Starting to get a little worried about the aluminum tail shaft, even though ive been told it should be up to it.
