Salo, who played for the Islanders from 1994-98, is 1-3 with a 2.97 goals-against average in five games against his former team. Brewer, dealt to Edmonton on June 24, 2000 for defenseman Roman Hamrlik, has no points in four games against the Islanders.
Isbister was acquired with Torres from New York at last season's trade deadline in exchange for defenseman Janne Niinimaa. Isbister's second game with the Oilers was against the Islanders on March 13. He was a minus-three with no points in Edmonton's 5-2 loss.
Torres, tied for second on the team with 11 goals, has never faced the Islanders.
Thursday's contest will be the fourth stop on a six-game road swing for the Oilers, who opened the trip with wins at Minnesota and Chicago before a 3-2 loss in overtime to New Jersey on Monday.
That snapped a three-game road winning streak for Edmonton, which also visits Philadelphia and Washington before returning home.
The Islanders' latest streak is a three-game winless stretch. New York lost 3-2 to visiting Calgary on Tuesday.
"We got sloppy," Islanders coach Steve Stirling said. "They were working all night. We were working in spurts."
Before the current 0-2-1 skid, New York had won six in a row. The Islanders suffered through a seven-game losing streak less than three weeks before that run.
Tuesday's defeat was the Islanders' first at Nassau Coliseum since Dec. 4, ending a seven-game win streak there.
The Islanders have won four straight against the Oilers.
