News from the Harrop Engineering team. The latest creation that we encountered from the hallowed halls of Harrop Engineering is an already very rare Holden HSV GTS which, as a tuned version, should probably only be found in double-digit numbers. At least so far, we have only presented one more Holden HSV on tuningblog.eu. At the end of last year it was the weaker 80PS Holden HSV GTS from Walkinshaw Performance Products with at least 700PS. We know a few details about tuning the Holden HSV GTS from Harrop Engineering. What we have learned we have listed below for you in a small summary.
