Before this motor was in my Zed it had a rather colourful history.
It started of in a Skyline then made it way to a 200B and lastly before me, it was in a 9 second Rail-Drag Car running 27 Pound Boost with Twin 2" SU's Holly Fuel Bowls and 1/2" dual fuel lines and a BIG Plemum chamber and huge turbo....I tuned it/modified it for road use - 23 Pound Boost, smaller turbo (not much), smaller plenum chamber but positioned for better flow, Stroked with 280zxCrank, Oringed Block, Cam, etc etc the 
list goes on and on...
Anyway here is a reprint from 'Wots Hot/Turbo Australia'
