I owned 5 Syclones over 25 years, from mild to heavily modified. The Syclone did not have anything in common with the GN/GNX.. it was based on the 4.3 truck engine that was basically a stock LB4 with hyprutectic pistons and nodular iron main caps, 700r4 transmission with a modified valve body, Borg Warner 7742 xfer case, and stock s-10 rear end. Syclones were fun on the street due to their AWD, but a significant investment was needed to make one go 10's and survive. From a dig at a light it is very hard to beat even a stock Syclone if the driver put a couple of pounds of boost against the foot brake.
The Syclone was inferior to the GN in just about every way, the Turbo 3.8 was a much more robust and well-thought out platform. The Syclone was cobbled together with parts that generally already resided in the GM parts bin.
BTW.... Your story about the Syclones going to Sweden is accurate, I was good friends with the guy who did a lot of the shipping for them. I believe the fastest AWD title still resides with Robert from Sweden - 8.9x as I recall.
