http://gruppe-s.blogspot.com/2010/02/gruppe-s-vr38dett-stroker-crank-in.html

Gruppe-S is currently working on developing the most Advanced Stroker Crank available. CNC machined with updated Oil Drilling will enhance Higher RPM ranges and resolve High horsepower oiling issues.

ETA on the finished prototype is one more week, then we'll begin the testing stage.

Expected new displacement on this Stroker kit will bring up the VR38 to a range from 4.0L to 4.3L. Updates on this VR38 Stroker kit will be up soon.
