I wouldnt say best, Id say slowest !
Just about any cheap import with the boost wound up can beat 90% of our local car'*.
The only local ones which seem to be doing anything half decent in terms of power are Ford. But realy ford arent australian. They are American, Ford just tries to market there product as australian for australians......
We still dont get the same models you guys do, so i gues there is some truth to it.
Holden still do not offer a boosted or even charged 6 or 8 in there line up. The only supercharged holden was the VT It just runs the M90 charger.
Ford though have a turbo charged 6 and 8, Plus a super charged V8 on the local market here.
With a few mods they make some decent power.
Holden have realy droped the ball over here. One example of a holden i think you would have in america is a Vauxhal Monaro. Nice car
But back on topic. VN - VS ran a holden 308 v8, or the buick v6 in the vn - vr and the ecotec in the vs and up.
It wasnt untill the VT'* that holden started useing ls1'* etc. But it is possible to drop an ls1 into a VN - VR with the sub frame from a 308 and some mods.
There has been a couple of blokes over hear that have imported a m62 and manifold from american and made it work. If the manifold etc bolts down i will just need to fabricate an elbow from the rear of charger pointing towards the side of the car so i can fit a TB etc.
I will allso possibly need to get my hands on some pulleys and belt tensioner'* and a alternator bracket aswell.
Sory if im rambling lol its pretty late here and ive had a full on day at work
