2443 Turbo/Rocky Jennings Oxyboxer with MS230's and Nickies.
One of Australia's most bad ass VW engines is going to be for sale soon.
The engine is a highly modified 2443CC Oxy Boxer, built for turbocharging. It is the ultimate in air cooled that I have been able to build. Yet its
primary purpose is to be a street engine, and make a reliable power figure of around 400hp.
The engine is currently disassembled, and is being refurbished with new seals and a few updates having sat for the past 10+ years.

Its in the process of another update/rebuild. Life caught up with me when I finished building it last. It was complete but not perfected or tuned as
such. I then got side tracked with house renovations, marriage and children. But Im slowly getting projects knocked off now and am working on it
again.
