Yep thats pretty close...Holden had injected the black 2002 Holden 6 but was considered long in the tooth. Holden intended to use the Buick sourced V6 but GM weren't in a position to supply at that time. Nissan was approached and built the RB30 which as far as I know was unique to the Holdens. The Holden 308 was planned to be dropped so the RB30 turbo was produced as a performance alternative and was used to great effect as a police pursuit car in Aussie and NZ and has become a legend. We now also know that Holden had a rethink about dropping the 308 and continued it for many more years before replacing it with the Chev Gen 3.
