After a goalless draw in their debut FIFA-recognised game against Haiti in March, Kosovo came into Wednesday's friendly in Mitrovica looking to break new ground.
They managed that 10 minutes before half-time when already 2-0 down, Kaiserslauten forward Bunjaku slotting home after Turkey goalkeeper Volkan Babacan had spilled the ball at his feet.
Goals from Ahmet Ilhan Ozek and Bilal Kisa had put a youthful Turkey side in control before that, and the visitors pushed home their advantage after the break.
Half-time substitute Olcay Sahan rattled in a third, before Mustafa Pektemek claimed a brace and Alper Potuk added a sixth from the penalty spot with three minutes to go as Kosovo tired.
After clearing a Kosovo corner, Turkey broke through Pektemek, who crossed from the left and, after a defensive slip, Ozek slammed home a finish from 14 yards.
The keeper was again called into action after shortly afterwards, flying high to his left to tip Tarik Camdal's dipping volley behind for a corner.
Kosovo's insistence on playing the ball out from the back was fraught with danger on a slow-looking surface and it proved costly as they conceded a second goal 11 minutes before the break.
A fourth followed five minutes later, Pektemek stabbing home from five yards after Mushica had parried Potuk's rasping drive from the edge of the box.
Pektemek was on target again on 71 minutes, heading into an empty net after being teed up by Sahan before Potuk had the final say on what was a historic day for Kosovo.
