"The car's now good as new, hopefully better," the 24-year-old said.
"Once we got the car back from the panel beaters it was a very busy few days putting everything back together ... my crew have got normal day jobs, so everyone came around and worked nights to have it ready.
"I'm very grateful for everyone's help, I'm very glad to be here."
Ordynski is another surprise starter.
The 50-year-old former national champion ended a long association with Mitsubishi at the close of last season and has sat on the sidelines this year, until a last minute call up from Toyota.
Ordynski, from Adelaide, will mark the 30th anniversary of his first Australian rally Championship start with a run in an ex-works Corolla usually campaigned by Martin Lintott.
"It's great to get back behind the wheel, today has reminded me what I love about the sport and what I've really missed this year," Ordynski said.
"The Toyota is very impressive, very nice to drive, and I'm coming to terms with it ... I think I am as quick as I can be in the slow corners but need to get more confidence for the quick ones."
Today's Shakedown stage in the Mt Crawford forest gave the major contenders for the Toyota Rally SA a final run before the weekend's serious competition begins.
Toyota's Neal Bates topped the timesheets with a 1m 33 second best run, followed by Subaru factory team twins Dean Herridge and Cody Crocker, the series leader and defending champion.
"It's time we got on with it," a relaxed Bates said, "so I am pleased how good the car now feels here, I hope we can be a serious contender this weekend."
Mitsubishi's Scott Pedder was a second shy of the Subaru's with a 1m 36 second run, followed by Toyota's Ben Barker and Steve Glenney (Subaru) in the 1m 37 second bracket.
Ordynski was next, recording a similar time to Kevin Shaw (Mitsubishi Lancer) and Monkhouse.
Taking it easy, Simon Evans (Toyota) rounded out the top 10.
The Toyota Rally SA, round four of the Globalstar Australian Rally Championship, kicks off with a promotional start in the main street of Tanunda tonight.
