Hello guys
I was at Frankfurt IAA motorshow this weekend, so I went at Alpina since I own one the let me in and show me what features the new cars has etc. So I came across the N55 biturbo engine that they have stationed at their stand. What I could see was the turbos was exact the same as the ones I got in my B3 biturbo (got RB turbos now). The developer told me they had upgraded the internals and that the brand was Borg Warner, he didn't tell what kind of wheels etc was put in but my guess would be that they remind of RBs or Vargas stage 2, maybe a little less or so. The guy told me the car was equipped with oil coolers at both sides which also cooled down the water. Seemed like it had an upgraded intercooler when compared to the stock one in the previous models.
Here is some pics, last picture is from the B6 Biturbo 540hp version, also had borg warner upgraded internals when compared to the 507hp version:
