i have an SV3800 as my daily driver, it gives the v8's a run for there money. being only a buick V6, its no rocket, but 200km/h no problem (dont tell dad!)
along with these the walkinshaw adn the A9X for sure. cant forget that crazy prosche killing 427 monaro either.
as for the utes, the brute utes are stock besides some safety features, and yes, they need to be in GT. ASAP
