VU Ute 3.8 S V6
I'm sure you've heard this before but... first things first - i'm looking at doing a few things to see what kind of power i can get out of my car (without the use of forced induction) and i want to make sure everything is compatible.

I'd like to get a roller rocker set which will be able to be used alongside a Crow stage 2 cam. My guess is the YT 1.8's? I'm also considering a bored throttle body as well as the manifold insulator and plenum spacer from MACE.

I currently have a 2.5" catback exhaust with advance extractors and will be replacing the current cat converter to hi-flow.

Going to be buying new diff gears - not too sure whether to go for the 3.7's or 3.9's - does anyone know approx. how much the 2 would affect fuel economy on a 3.8L V6 per 100km?

Aside from that, maybe an engine clean and a good tune.

Anything else you guys can suggest?

Brux.
