Cowboys winger Jordan Kahu.

A defiant Jordan Kahu says he is determined to show the Broncos what they have lost as he and a "pumped" Josh McGuire prepare to rumble against their former team-mates at Suncorp Stadium on Friday night.

Kahu has harboured a desire to play in the No.1 jersey since he was a schoolboy star at Keebra Park High and impressed in the custodian’s role in the Cowboys win over the Dragons in round one.

The Kiwi international said he would "be lying" if he said there was no bitterness towards Brisbane after he secured a release when it became clear he was no longer part of Anthony Seibold's plans.

"I’m pretty keen to show them what they lost to be honest and obviously prove to the Cowboys that I belong here and belong in that No.1 jersey. I'm pretty keen to impress a few people," Kahu said.

"The Dragons game was my second game at fullback in a long time and I was just trying to build on my performance from the trial and this week I'll be trying to build on top of that as well and get more involved and just get used to what comes with fullback again.

"I feel comfortable back there."

Cowboys veteran Gavin Cooper said Kahu and McGuire had circled March 22 on their calendar the moment they arrived in Townsville and he expects McGuire to go hard on Friday.

McGuire, an Aspley Devils junior who debuted for the Broncos in 2009, said it’s always a special game between the two clubs and there’s a mutual respect.

“I was there for a long time and I know the capabilities of all the players there. It’ll be different being on the other side of the fence this week but I'm looking forward to playing some good footy,” McGuire said.

“The Broncos are a very special team.”

Kahu said knowing this game was always in the back of his mind this week, he’s pretty excited to be running out in different colours.

“I think catching a bus to the stadium, going into the other change sheds will probably be weird, but as soon as I run out I'll be back to normal again. I've played most of my games there, I know that ground pretty well," Kahu said.

“It’s always close to a sellout and the history that these two clubs have had over the last 25 years or so has been pretty crazy.

"Every game's always tight and both teams always want to stick it to each other."
