vs ss or vt ss or somthing else that is the question

For up to $18K you could easily pick up a VS HSV clubsport in a manual. There's a few on carsales and carpoint for around $13K - $18K. Some have K's around the 130,000 mark. Or there's a few Senators with a stroked 5.7 215kw for a similar price but I think they're only autos.

Someone correct me if I'm wrong but does an LS1 have to run on Premium 95 or 98 petrol? The old 304's didn't.

ls1's dont need premium unless tuned for premium,and if your worried about running premium your in the wrong game as most ls1's will be tuned for it unless you dont want max HP that is and i think we all want that
you will be able to get a vx ss for 18k
