A light single engine aircraft pilot had an NMAC with a light twin on approach to Runway 27R at GFK.

Narrative

I was coming in to GFK from the south; Runways 27R and 27L were in use. Runway 27L is further from the FBO than 27R so I requested 27R when I contacted Approach. They stated they would pass my request on to Tower. I was then passed over to the Tower frequency handling the south runway (27L). They asked that I fly a left base for Runway 27R and then passed me over to Tower frequency for 27R. I was advised by Tower that I would be following a [light twin] on a four mile final. This was just prior to me passing through what would be the final leg for 27L. As I came abeam 27L I asked Tower if I was cleared to turn final for 27R as I did not have the [light twin] in sight. I was then told to turn right eastbound and they; [the light twin]; would pass off to my left. I believe they said they would have him turn right away from me as well. As I started my turn to the right (east) and before there were any further transmissions I saw the [light twin] pass immediately off to my left. He banked to the right away from me as well. Tower then cleared the [light twin] to land and advised me to follow him and I was clear to land 27R; number two.
