We’ve  been developing kels since 2008, when it was purchased from a US team. Previously built by Jackson Stewart of Unitech Racing and campeigned in Grand-Am’s Koni Challenge, this Z was a steal of a deal as it included a parts car (literally a brand new 350z roadster), spare engine, transmission, all the MoTeC goodies you could dream of and a true proper motorsport build. Unfortunately the car was pretty beat up when I acquired it, and it took a lot of love to get it up to speed. The car has been great to me and we’ve learnt a ton with it and have since built it up into a capable and fast GT car. The ultimate goal for the Z is to make it into a true professional level GT car that is capable of doing sub 1:20 laps at Mosport. The goal is to do this without forced induction or excessive modifications to the car that detract from that true GT car genre.


You can read all about the current happenings of the Z here, as they are continually updated with all of our ideas and developments. For up to the minute updates on the car, follow us on instagram @onpointdyno to see the action as it unfolds.


Over the years we have amassed a number of good videos of the Z, the most popular of them being the dyno tuning videos that people love. Check them out here on our YouTube channel. Be sure to also check the Speed Academy YouTube channel for videos featuring the Z.
