"We don't want to just go there and make the numbers up," McIntyre said.
"We are there to go and make it a good contest and go and give a good account of ourselves. We are there to cause an upset if we can, we would love to be able to turn them over. But we realise it's a big ask. We also realise they're a very, very experienced side and we're under no illusions it would be probably one of the biggest upsets in New Zealand football."
Steve Bayard will stand between the sticks for Lower Hutt given Basalaj's absence, which will cap a hefty elevation for the custodian who spent most of the year playing for the club's third team.
Lower Hutt captain Hamish Watson, who has spent the past few weeks training with the Phoenix, will be looked upon by the young guns to provide strike power up front. He also found the back of the net in their quarter-final and semifinal victories.
Central, who finished third in the Northern Premier League this year, stormed their way to the Cup final with a 6-0 win over Miramar Rangers at the final-four stage, while they also beat Eastern Suburbs 2-0 in the quarter-finals.
Veteran striker Paul Urlovic has overcome an ankle complaint and will line up on Sunday in search of his fifth winner's medal, while Vicelich could make it No 4 if Central were to claim victory.
Central coach Chris Zoricich said the impact of Vicelich, who has amassed a record 80 caps for the All Whites, couldn't be underestimated.
"He was great last year as well. Ivan could take the easy road and not bother coming down and playing for Central to be honest ... Just having him around and his aura and experience around the changing room. He's really professional, he's always the first one at training, he's always there so it's just great for the young lads to see that he's still doing it at that age and is still fully committed."
Kickoff is scheduled for 2.30pm at Newtown Park with the final of the women's national Knockout Cup between Massey University and Three Kings United set to start at 11am.
