Chris Adams' Holden is "all go again" in time for today's national championship V8 round at Teretonga Park, near Invercargill.
After two days to forget in Timaru last weekend where he was unable to complete any of the three races due to mechanical issues, the Mosgiel driver is hoping for better fortune.
His team found a bend in the oil pump shaft that had caused the majority of his problems and the car "went really strong" in testing on Wednesday.
Heading into the fifth round, Ford driver Kayne Scott, of Hamilton, has extended his lead in the NZV8s to 31 over defending champion John McIntyre.
Scott said his team has adapted well to changing the set-ups for each circuit.
"The car is very strong - it is good under brakes, it gets the power down well. At the first round of the series at Taupo we had a weapon and then the conditions changed and we couldn't get the set-up quick enough.
"Now we have a good understanding of the car and we are a lot happier."
Top Holden campaigner Andy Booth is 157 behind Nelson's McIntyre on 531, with Gold Coast-based Craig Baird close behind on 521.
Auckland's Angus Fogg charged up the points standings last weekend, coming from eighth overall to fifth after two second places in Timaru.
His overall result would have been better if he had not slid into the wall on the final laps of race three, which dropped him down to 15th.
John Whelan was looking forward to qualifying this weekend after a mechanical failure did not allow him to post any lap times in the Timaru session - relegating him to the back of the grid for all three Toyota Racing Series races.
The Dunedin driver said "everyone is right there on the pace" in the lead-up to the racing in Invercargill, but he was hoping for a top five finish.
In his first practice run yesterday, Whelan clocked the fifth fastest time.
However, the threatened rain could "chuck a spanner in the works" as he had not had any experience racing the Toyota in the wet, as this is his debut season.
