This engine was originally in the blue/purple "Weekend Soarer" I purchased years ago before parting the car out and returning to stock and selling it. 

No one offered me any serious money for the engine I had, so after sitting in my shed for a few years I decided to keep it and use it in the trackday soarer - when I dropped the sump to check the condition of the bores I found a JUN/Cosworth forged bottom end it it that no one knew about.

This engine made 331 rwkW on a Mainline Dynolog dyno at 19 psi boost on an identical driveline.
