Not in this case my friend. We are currently building a car very similar to Dales new project, with the same power to weight ratio of a v8 touring car for less than $10,000 ,a fraction of the price of a built GTR . Very fast cars have been built for alot less and there are also sedan classes , mid mount an RB in anything light like a silvia= alot of fun.
Dirt circuit is currently the largest motor sport in S.A With aprox 400 + cars but is largely unknown in Adelaide ( Although a track within 100km of the CBD is in the planning). Speeds of 200kph are regularly achieved on the 9 tracks in S.A . Its not oval racing its circuits including straights chicanes and hair pins, club membership is $30 a year and $10 entery fee per race meeting which makes it the fastest cheapest motor sport around, anyone keen? There's nothing like drifting a car at 150 kph+ with 8 other cars inches away, especially when you are blitzing a blown 600hp mid mounted chev in your jap powered weapon .
